It also support the gm950 Plus radio. The N2 low tier (4 channel, non-display radio) offers basic 5 tone signalling and the N3 mid tier (128 channel, 3 digit display) product that offers additional capabilities including Multicall 1, 000 and ID Decode. Display: In addition, a Hand Held Control Microphone (HHCM) is available as an option for the N3 mid tier radio, to cater for the markets where users require single handed operation. All models have these standard features. Higher tier models add additional features that are typically requested by more advanced or demanding users, such as the ability to individually call many other radio units in addition to just a central dispatcher. Since in many cases these more advanced users are found on large radio systems, the higher tier radios offer a large number of operating frequencies (channels), however the user benefits associated with the additional 5 tone selective calling features are applicable to any user, no matter how few channels they use. Also, in some systems it may be appropriate to provide certain users with a low tier radio, and other users with a more highly featured radio. Operation of the RSS is made easier by the use of this on-line user manual plus field based context sensitive Help. The Personality Validation feature may be used at any time to check for inconsistencies in the way the radio is being programmed. The User Manual is designed to be opened on a separate window to the main application, such that a 'side by side' presentation of the manual is available. Selection of the information presented on the contents list will take the user directly into the selected section of the document. The sections are provided such that each one supports a specific function of the RSS. The User Manual provides specific information on all windows, menus, fields, error messages, information / prompt messages and radio alignment. The User Manual is provided in Electronic form and the Print option may be used to produce a hard copy of the document. Radio Configuration Data. The Radio Configuration Data (Codeplug) includes all the programmable parameters within the radio. This data consists of the Radio Personality Data and the Radio Service Data. Radio Personality Data The functionality of the radio is defined by the current settings within the Radio Personality Data, and includes customer specific items such as channel frequencies and option button functionality. Radio Tuning Data The radios RF characteristics are defined by the Radio Alignment Data. These parameters are factory pre-set but can be modified via the Service Tuning menu to allow for realignment and repair of the radio. Data Entry and Key Usage. The RSS system is configured to run as any other Windows based utility. The Mouse can be used on any toolbar or window to select the item or field to be edited. Reference is made in the User Manual to several types of 'Box', the description of the function provided by each type of 'Box' is given below. 'Dialogue box'; this is a box used to request information from the user and provide information to the user. An example of this is the 'File Open' dialogue box which would ask for information on the specific filename of the file that the user wants to open. Windows also uses dialogue boxes to display additional information and warnings, or to explain why a requested task could not be accomplished. Most dialogue boxes contain options, each one asking for different information. After the requested information is supplied, a command button is enabled to carry out the command. An example of this is the 'List Files of Type' combo box on the 'File Open' window where the different types of file are provided for direct selection. Check box: this type of box allows an option to be enabled or disabled. When an option is selected (enabled) the box will contain an X, otherwise it will be empty. Option selection box: there is a grey square (containing either a single downward pointing arrow or two vertical arrows pointing in opposite directions) at the right of this box. Clicking on the single arrow will display the list of options available. The cursor is used to select the required option. If 2 arrows are in a box they are used to increment a setting for a timer etc. By clicking the cursor on an arrow, a setting will be incremented (up or down, depending which arrow is used) by a pre-defined step size. Note : The timer values and their step sizes are actually real numbers, however, this RSS will only display them in integer. Therefore, the user input timer values will be validated and rounded by the RSS to the nearest integer to be displayed. A window may contain screens which have been set up in a file card type system. These screens may contain 4 control boxes, OK, CANCEL, NEXT & PREVIOUS which are actioned using the cursor. The OK box saves the screen to memory and will then display the window again allowing the user to select another screen for editing. The Cancel box clears the screen without saving it. Next clears the displayed screen a89:;<=nd then displays the next screen. Previous also clears the screen but will then display the screen prior to the one just cleared. The code plug held in the PC memory can only be written to a Radio using the Write Radio menu selection. Where a Mouse is not available a 'Hot' key selection is provided, such that any window or function can be selected. The 'Tab' key is used to move around the Window and Up/Down Arrow keys are used to select the required option within a field. Start Up Window Using the mouse control and double clicking the GM950 Icon (displayed in the Program Manager screen of Windows) will cause the RSS to run up and display a Banner Screen superimposed over the main window. The Banner Screen provides the following information about the RSS system : Title : Containing information about which radio type the software is used. Version : The software version number and the date at which it was first issued. Serial Number : The unique serial number of the RSS software. Registered To : The name of the user and company that the software was registered to at the time of installation. Copyright : Gives warning of the Motorola copyright. OK button : When this is enabled, the banner screen is closed and the main selection window of the RSS is now displayed. MAIN WINDOW STRUCTUREMAIN WINDOW STRUCTURE Main Window. The main window contains, from the top, a Title bar, a Menu bar, an Tool bar, an area in which the selected subsidiary Window is displayed and an information bar at the bottom of the screen.

Selecting an item on the menu bar will cause a sub-menu of the chosen item to be displayed and allow the user to select the required window. Tool bar: The tool bar provides direct access to the following functions: File Open. File Save. Read Radio. Write Radio. Help. Personality Validation. The functions File Open, File Save, Read Radio, Write Radio, Open User Manual, and Personality Validation correspond directly to their equivalent menu commands, and have the same operation. The Help function opens the Help window showing the text appropriate to the field currently being edited. Information Bar: The information bar contains the following fields : Model Number : Updated with the model number from the information contained in the code plug data currently held in memory. Data Source : Updated with the source of the code plug data currently held in memory. It will be either the filename if loaded from a disk file, or the word 'radio' if the information has been read from a radio. These fields will initially be blank until code plug data has been read. NOTE: Some of the subsidiary windows contain another information bar which displays Minimum and Maximum values for the currently selected feature within the screen and the allowable step size. FILEBFILE Selection of the different windows available in the menu displayed after File has been selected will support the user in all aspects of file management, e.g. save, print, open etc. Further selections available provide the user with the ability to both read and write to the radio, and exit the application.

Files are selected by choosing the file type from the List Files of Type option selection box, selecting the required file in the Files box and operating the OK button. Different drives can be selected from the Drives option selection box and all directories within the selected drive will be displayed in the Directories box. Selecting a directory will display its contents in the Files box. Three types of file are displayed when the List Files of Type option selection box is chosen, they are Personality (*.per) files, option board init data (*.fre) files and All Files (*.*). The All Files (*.*) option allows personality files and option board data files to be identified that have been saved with an extension other than the preferred .per and '.fre'. The file format is checked by the RSS software to determine the actual file type and if it can be opened. FILE SAVEFILE SAVE When selected, this window allows the current opened file to be saved. Existing files will be shown in the Files box of the displayed default file type (.per) in the List Files of Type option selection box. Directories of the default drive will also be shown in the Directories box. The RSS cannot save the option board data to *.fre files. To save a file, select the required drive, appropriate directory and file extension (.per). If required, enter a description (max. 100 alpha numeric characters) of the file in the description box, name the file using the File Name box and ensure the appropriate extension (as displayed in the list files of Type box) is added after the name. Operate the OK button to store the file. If an existing file is being updated, then by selecting it in the Files box will cause the existing information relevant to that file to be entered into both the Description and File Name boxes, where it may be edited. Operating the OK button will now cause a warning screen to be displayed, informing that the file already exists and offering the choice of over writing the existing file or cancelling the operation. READ RADIOREAD RADIO This option allows the user to read a radios code plug information into the PC, but first the radio must be connected to the PC communications port using the appropriate cables and RIB box. The RSS will first validate the radios code plug prior to reading it, if this fails a warning screen will be displayed informing of the incompatibility between the RSS and code plug. WRITE RADIO WRITE RADIO This option allows the user to write the edited RSSs screen files into a radios code plug memory. The radio must be connected to the PC using the appropriate cables and a RIB box. Selecting the write radio option will cause a warning message to be generated informing the user that the code plug currently resident in the radio will be overwritten and offering the options to continue or abort the operation. Continuing the operation will cause the RSS to validate the code plug and if this fails a warning screen will be displayed informing of the incompatibility between the RSS and code plug. The RSS writes only the personality data into the radios code plug memory. Transmitter and receiver alignment data can only be changed using the service section of the RSS. kK5K5Z[\K5K5]JK5K5_`sK5K5abcdefK5K5ghijklmnopqrstuvwxyzK5K5{|}~SK5K5WK5K5YK5K5K5K5RK5K5K5K5K5K5K5K5K5K5K5K5PRINTbPRINT Selection of this item will display the Print screen, which contains five dialogue boxes: Type of Printing, Printer Port, Print to File with an adjacent file name box, and a Comment box.

These features are grouped under their appropriate heading in the File Card system displayed in this window. Each screen contains the 4 control boxes, OK, CANCEL, NEXT and PREVIOUS. BUTTONShBUTTONS Up to six buttons are programmable by selecting a feature from their Option Selection Box. The non display radio may use 4 of the buttons (1, 2, 3 and 4) for channel selection and the display version has a dedicated rocker type switch for channel selection. There is another option button (7) if the Hand Held Control Mic option is used. On each N2 and N3 model, there are 6 function buttons. On N2 models, four of the function buttons are usually programmed as channel selection buttons, but they may be used for other functions (E.g.: Call 1, Scramble Key Select etc). Certain features require a visual indication of operation status (Repeater Talk around, Call Forward, External Alarm, Scrambler On, Scan). On the N3 models, these features are indicated by icons in the display. On the N2 models, these features are indicated by the Green option LED. Since there is only one option LED, it can only be allocated to one option. Some other features that can be programmed onto function buttons do not require a special icon or option LED to indicate their operation (Call 1/2/3, Scramble Key Select, Emergency, Nuisance Delete, Memory Channel 1/2, Select, etc). Monitor has a dedicated Yellow LED indicator, as well as an icon in N3 models. Once programmed, a button becomes a user control which gives the user the option to enable/disable the feature.

TXTX Selection of this option enables the global features of the transmitter to be set. The screen contains the 4 control boxes : 'OK' , 'CANCEL' , 'NEXT' , 'PREVIOUS'. POWER LEVELSPOWER LEVELS On both models, two transmitter power levels are available (high or low) on a radio wide basis. Once the power levels are set by the radio service software (RSS), each channel can be configured as a high power or low power channel. The two power levels cannot exceed the specified power parameters for the radio. The two levels are very much easier to set up than on other radios - the service technician simply types in the absolute power level required (e.g.: 5 for 5 watts, or 15 for 15 watts) and the radio will automatically provide this power on the relevant channel. These power levels can be cloned from one radio (or archive file) to another radio which has the same model number. TX TOT TIMETX TOT TIME This is the transmitter time out timer. The time set in this field (0 -268 seconds in steps of 1secs, set using the option box up/down arrows) defines the allowed time for radio transmission. If the radio is still keyed at time out, the radio will automatically dekey and revert to the receive mode of operation even though the radio is still keyed. If enabled, the radio will emit the audible alert for an invalid key operation for as long as the PTT remains pressed. This feature also prevents a radio channel being locked to a radio whose PTT button has been inadvertently operated because the mic has not been put on hook correctly. If set to 0 the radio has unlimited transmit time.

The choices available are If Carrier or Always. Note: Forced monitor does not prevent transmission if a channel is busy, for that use PL/DPL Lockout etc. When the If Carrier option is selected and carrier is being detected, pressing the PTT will put the radio into monitor mode (Auto Reset squelch state) and the error alert will sound until the PTT is released. The radio is now in monitor mode. Pressing the PTT for the second time causes the radio to transmit, assuming any programmed transmit admit criteria is satisfied. When the If Carrier option is selected and carrier has not been detected, pressing the PTT for the first time will put the radio into transmit. The Always option means that forced monitor will be applied to every first press of the PTT when a user attempts to transmit. The first press of the PTT button will cause an invalid key operation alert to be sounded until the key is released. FORCED MONITOR ALERTFORCED MONITOR ALERT This gives the user the choice of having an alert sound when forced monitor is invoked by the radio at times of attempted transmission. ID REPEAT TIMEID REPEAT TIME This time interval (0 -268 seconds in steps of 1secs, set using the option box up/down arrows) defines when the radio will automatically send out its ID.

CHANNEL SPACINGCHANNEL SPACING Previously, radios which had 20/25kHz channel spacing required a lengthy bench tuning process to change the stored data such as TX deviation and RX squelch settings from the factory standard 25kHz to customer required 20kHz. Now these 20kHz settings are achieved simply by enabling a radio option in the RSS, which causes the GM950 to use factory loaded tuning points for 20kHz.

AUTO RESET TIMEAUTO RESET TIME This is the time period which the radio will wait before closing its squelch and returning to its receive squelch state. The timer can be set from 0-66 seconds in steps of 1 sec, set using the option box up/down arrows. EXTERNAL ALARM MODEEXTERNAL ALARM MODE External alarm is used to sound a car's horn, or flash the lights, to inform a user who may be away from his vehicle that the radio has been called. The external alarm feature operates a remote relay which in turn may be wired to the horn, lights or other device. The duration for which the external alarm is asserted can be programmed to be from 2 - 32 seconds. External alarm is stopped if the radio is switched off, or if any of the radio buttons are pressed when the alarm is being asserted. When EA is being asserted pressing any button will cancel the assertion of EA ( stop the car horn, lights ) and also action the button. For example pressing PTT will both cancel EA and keyup the radio to answer the call. External Alarm mode is programmable on individual calls for the following: 1) Always activated on Select 5 individual calls. 2) User Selectable, activated on individual Select 5 calls. External Alarm mode is programmable on group calls for the following: 1) Always activated on group and individual calls. 2) User Selectable, activated on group and individual calls. If either of the user selectable options is programmed into the radio then external alarm can be enabled/disabled by an option button programmed as external alarm. EXTERNAL ALARM DURATIONEXTERNAL ALARM DURATION The time period for which the external alarm mode remains active after receipt of the appropriate call, is set in this option box. Its duration is 2-32 seconds in steps of 2 second, set using the option box up/down arrows. EXTERNAL ALARM DELAYEXTERNAL ALARM DELAY External alarm will not activated once the radio received a call, it will delay for a certain time before it actually activates the external alarm. This will allow the operator near the radio to have an oppurtunity to turn off the external alarm before it sounds. This feature applied for MDC emergency only. This field defines the delay time before activation of the external alarm. OFF HOOK FUNCTIONOFF HOOK FUNCTION The Off Hook function is activated/de-activated when the mic is placed on / taken off its hook. This function allows the user to toggle between auto reset squelch mode and receive squelch mode. On going off hook, the radio enters auto reset mode and when going on hook, the radio enters receive squelch mode, unless either monitor mode 1 or 2 has been selected via the monitor button, in which case the monitor button overrides the hook function. The option box down arrow is used to display the off hook functions. These are Disabled, Timed, Permanent. Permanent Hook: If this option is selected, the radio will remain in auto reset squelch until the user goes back on hook. Timed Hook: If selected, the auto reset timer is counting down from the moment that the mic is lifted off hook and it will continue to count until it expires, or until the mic is placed on hook. Disabled: If selected, the radio will ignore the operation of the mic hook switch. See Squelch Help for further information. AUTH. REQUEST MON TIMERAUTH. REQUEST MON TIMER This timer can be set from 0-15 seconds in 1 second steps by using the up/down arrows in the option selection box. This is the period of time during which the radio will wait for a reply to an authorisation request by the user, before closing the squelch and reverting to its idle state. It allows the user to determine if the request has been received, by whether or not a reply (an alert tone or sequence) to the request is heard. If this feature is enabled and after the authorisation request has been transmitted, the radio adopts auto reset squelch for the duration period of the Authorisation Request Monitor Timer. The radio is unable to transmit during this period. CHANNEL BUSY LEDCHANNEL BUSY LED Selecting this will cause an X to be displayed in the box and the RED LED will flash when ever the channel is busy.

The choice is either the last channel or a designated channel. DESIGNATED CHANNEL+DESIGNATED CHANNEL This option selection box is used to define the channel to which the radio will revert on power up if Designated has been chosen from the Power Up Channel options. The radio will either power up on the channel that it was on when it was previously switched off, or it will power up onto a code plug programmed designated channel. If the power up on last channel feature is enabled and the stored channel number in the radio RAM proves to be invalid then the radio will power up on the designated channel number instead. DEFAULT ENTRY MODEDEFAULT ENTRY MODE Entry Fields Only the N2 model radio does support entry fields. Entry fields have an associated display and icon. The icon indicates the currently active entry field. The radio supports the following entry fields: 1) Multicall 1. 2) Multicall 2. 3) Channel. Default Entry Fields The radio also supports a default entry field (not N2 models). The default entry field shall be active when: 1) The radio is powered on. 2) On time-out of a non-default display, if the inactivity timer is programmed. 3) A press of the default entry fields associated button whilst a non default entry field is active. A non default entry field can be selected by the press of the entry fields associated button. This feature allows the radio to be configured to provide the most user friendly operation. On N3 models, the default entry mode, which will be operational after power-up, will define the parameter altered when the up/down control is pressed and can be selected as one of either: Channel. Address (Multicall 1). Status (Multicall 2). To change parameters from the default entry one, the radio must be programmed correctly to allow the entry mode to be temporarily changed. e.g.: If default entry mode is Address but the user needs to change channels, then a function button must be programmed as Channel Mode. After the (programmable) defined period of inactivity, the radio will return to the default entry mode. The appropriate mode icons will be displayed to indicate the current entry mode. Note: It is not possible to alter channel, address or status when in scan, however if the default entry mode is Channel and the current (home) channel is an auto scan channel, then pressing a function button to change address or status will initially stop scan, but after 10 seconds of inactivity, scan will re-start. DEFAULT ENTRY MODE: After powering up, the radio will go into the mode of operation selected in this option box. The choice is either Multicall 1, Multicall 2, Channel or Scan. TIME TO DEFAULT ENTRYTIME TO DEFAULT ENTRY If the user puts the radio into a non default mode of operation by the operation of a pre-programmed function button and no further activity is detected by the radio, it will remain in this mode for the default period set in the option box by use of the up/down arrows. If the entry is 0, then the selected mode will remain active until de-selected or the radio is powered off. The duration is 0 - 32 seconds, selectable in 2 second steps. MEMORY CHANNELMEMORY CHANNEL These option selection boxes define the channels that will be associated with a function button when buttons are defined as memory channel 1 and memory channel 2.

SYNTHESISER REFERENCE FREQUENCYkSYNTHESISER REFERENCE FREQUENCY This option allows the reference frequency for either or both the receiver and transmitter to be altered slightly and prevent any spurious frequency causing interference with this channel, or other radios. The choices in this option selection box are: Auto. 2.1MHz. 2.225MHz. 2.4MHz. Auto is the default setting. RF LEVELRF LEVEL This option box is used to select the required transmitter output power for the channel. The choice is either High or Low. The actual power levels applicable to these options are set in the Per Radio window. TRANSMIT ALLOWEDTRANSMIT ALLOWED When a channel is selected, the chosen option displayed in this option box defines the operation of the transmitter when the PTT button is pressed. The choices are Always, If Channel Free, PL/DPL Lockout, Past PL/DPL Lockout. ALWAYS: This option allows the radio to transmit whenever the PTT button is pressed. IF CHANNEL FREE: The radio inhibits any attempted transmission if carrier is currently being detected on the receive frequency. PL/DPL LOCKOUT: The radio will inhibit any attempt at transmission if carrier is detected on the receive channel, unless the PL/DPL code of the channel is being detected and the radio unmutes. PAST PL/DPL LOCKOUT: The radio will inhibit any attempt at transmission if carrier is detected on the receive channel, unless the PL/DPL code of the channel has been detected since the carrier was detected. Note: The carrier is assumed to be lost when the radio is keyed, so this criteria must again be satisfied after de-key. AUTO RESET TRANSMIT INHIBITAUTO RESET TRANSMIT INHIBIT Selecting this option will cause an X to be displayed in the box and this condition will be applied during auto reset. (The radio will not transmit during auto reset). FULL LOCKOUT FULL LOCKOUT Selecting this option will cause an X to be displayed in the box and the user will be prevented from both transmitting and monitoring (listening) to traffic on the channel. The radio will now only unmute for the correct received squelch code. TIME OUT TIMER ENABLEDTIME OUT TIMER ENABLED Selecting this option will cause an X to be displayed in the box and the Time Out Timer function will be enabled for this channel. FORCED MONITORFORCED MONITOR Selecting this will cause an X to be displayed in the box and the Forced Monitor function will be enabled for the channel. The forced monitor function is selected in the Tx File screen of the Per Radio window. SQUELCH MODE%SQUELCH MODE This operates like an 'ON/OFF' switch (mute and unmute) to control the flow of received audio to the loudspeaker. This screen defines the circumstances that will allow audio to be passed to the loudspeaker during normal receive operation, auto reset and operation of the monitor button. The radio provides the following Squelch Modes : 1) Receive Squelch Mode. 2) Monitor 1 Squelch Mode. 3) Monitor 2 Squelch Mode. 4) Auto reset Squelch Mode. Squelch Settings The following Squelch Settings are possible: 1) Open: For this Squelch Setting the radio does not have any signalling requirements in order to unmute. The loudspeaker is always open allowing the user to hear any channel activity including noise. 2) Carrier: This Squelch Setting requires that the radio receives carrier in order to unmute. 3) PL/DPL, or Code: This Squelch Setting requires that the radio receives some sort of continuous subaudible (PL/DPL) modulation in order to unmute. 4) Tone Signalling: This Squelch Setting requires the radio to be Called, for example by an individual call from a select 5 sequence. 5) Tone + Coded: This Squelch Setting requires that the radio receives both Tone signalling and subaudible (PL/DPL) Coded modulation order to unmute. Squelch Mode Squelch Restrictions The following restrictions apply to the squelch modes: Receive Squelch Mode can be one of: 1) Coded (requires TPL/DPL decode on channel). 2) Signalling (requires Select 5 decode on channel). 3) Coded+Signalling (requires TPL/DPL+select 5 decode). Monitor 1/2 carrier Squelch Modes can be all of the above, as well as open squelched. Squelch Mode Selection There are different ways of moving between the different squelch modes, the following methods are available: 1) Channel Change: Channels can be set to operate using different squelch modes, so selecting a different channel may well select different squelch operating mode. 2) Monitor Button. 3) Transmission (PTT, Call). 4) Timed Hook. 5) Permanent Hook. 6) Force Monitor. 7) Radio receives a call. Squelch: Monitor Button Squelch Selection The monitor feature allows the user to toggle between different programmed squelch modes: e.g.. Carrier and Open Squelch A quick press of the monitor button enables monitor 1 squelch override and a long press (greater than 2 seconds) will enable monitor 2 override. If enabled, an alert will be given for successful entry into monitor 2 button operation. Monitor operation described in detail below is designed so that the user perceives a change in radio squelch whilst he has the monitor button pressed. Releasing the button when the desired squelch is achieved will never cause a change in radio squelch. In the description below a monitor press refers to the action of pressing the monitor button, not a continuation of a press which occurred earlier. Radio in receive squelch. When the monitor button is pressed, the radio squelch will immediately change to that programmed to monitor 1. Releasing of the monitor button will not affect the radio squelch. Radio in receive squelch but in auto reset: When the monitor button is pressed, auto reset will be stopped, and the radio squelch will return to the radios programmed receive squelch. Releasing the monitor button will not affect the radio squelch. The radio will be receive squelched if the button is pressed for a time shorter than monitor long press and monitor 2 squelched otherwise. Radio is monitor 1 squelched. When the monitor button is pressed the radio squelch will immediately change to that programmed for receive. If the duration of the monitor button press subsequently exceeds the monitor long press duration then the radio squelch will change again to that programmed for monitor 2 and the monitor alert will be given. Radio is monitor 1 squelched, but in auto reset: Auto reset is overridden by selecting monitor 1 State. The actions are the same when the radio is monitor 1 squelched. Radio is monitor 2 squelched. Operation is exactly the same for that described when radio is monitor 1 squelched, in addition it will give a monitor alert indicating the radio is monitor 2 squelched. Radio is monitor 2 squelched, but in auto reset. Operation is exactly the same for that described when radio is monitor 1 squelched but in auto reset, in addition it will give a monitor alert indicating the radio is monitor 2 squelched. Remote close: This enables the squelch to be closed (remotely) after the radio receives a specific tone sequence. It is used with the Authorisation feature of the radio. After transmit and selective 5 calls the radio will return to the monitor state it was in previously. Hook Hook operation allows the user to toggle between Monitor 1 Squelch Mode and Receive Squelch Mode. On going off-hook, the radio enters auto reset mode. When on-hook the radio enters receive squelch mode (unless the user has selected either Monitor 1 or 2 Squelch mode via the Monitor Button). Hook type can be programmed to disabled, permanent or timed. When off-hook, the radio will adopt the auto reset squelch mode, unless the operator has previously selected open squelch, (by using the monitor button) in which case the radio will remain open squelched. Permanent Hook When the radio is programmed for permanent hook, the radio will remain in auto reset squelch until the user goes back on-hook. If the user has selected either Monitor 1 or 2 Squelch mode via the Monitor Button the radio will remain in that Squelch Mode on going back on-hook. Timed Hook When the radio is programmed for timed hook, the radio will remain in auto reset squelch until the auto reset timer expires or the radio goes back on-hook. If the radio has selected either Monitor 1 or 2 Squelch mode via the Monitor Button the radio will remain in that Squelch Mode on going back on-hook, or expiry of the timer. External Hook The accessory connector I/O hook input is OR'ed with the microphone hook switch. This means the radio is off hook when either the microphone hook switch OR the I/O input is in its off hook state. The radio is on hook when both hook switches are in their on hook states. Disabled Hook The hook switch will be ignored when hook type is programmed as disabled. Each screen contains the 4 control boxes, OK, CANCEL, NEXT and PREVIOUS.

The window will indicate the rec SQUELCH LEVELSQUELCH LEVEL The squelch softpots set the signal to noise ratio at which the squelch opens. The squelch value needs to be set at 7 frequencies across the frequency range. If the radio supports 20 or 25 kHz channel spacing selection, the radio stores separate tuning data for 20 kHz and 25 kHz channel spacing. Therefore, both sets of tuning data should be tuned independently. 1.

If a function button has been programmed as a monitor button, a user will have the ability to override the squelch controlled operation of the radio in either of the two ways set in these boxes. This enables the user to listen to traffic on the channel if the received carrier complies with the criteria selected with the monitor button. A quick press of the monitor button enables monitor 1 squelch override and a long press (greater than 2 seconds) will enable monitor 2 squelch override. If enabled, an alert will be given for successful entry into monitor 2 button operation. If in the auto reset mode, tapping the monitor button will cause auto reset and put the radio into the receive squelch mode of operation. A long press will put the radio into monitor 2 mode. and an alert will sound. If a monitor mode had been selected prior to transmitting, the radio will return to that selected monitor mode after the transmission. The options for monitor squelch operation are Open, Carrier, PL/DPL, Tone and PL/DPL + Tone. CARRIER: If selected, the receiver will pass any audio received to the loudspeaker. PL/DPL: If selected, only received audio from a carrier that has the correct PL/DPL code will be passed to the loudspeaker. TONE: If selected, only received audio from a carrier that has the correct tone sequence will be passed to the loudspeaker. PL/DPL + Tone: If selected, only received audio from a carrier that has the correct PL/DPL code and tone sequence will be passed to the loudspeaker. OPEN: if this option is selected, the radio will have no signalling requirements in order to unmute and everything will be heard at the loudspeaker. This includes received noise. AUTORESETAUTORESET This is a feature that is typically associated with signalling squelch operation but is also applied to coded squelch. On receipt of a selective call or upon dekeying the radio will enter auto reset mode in which certain squelch requirements are defeated. See appropriate section for more details on radio Squelch Mode Squelch Settings. Auto reset timer On entering into auto reset mode the auto reset timer will be started. The radio will reset to the previous Squelch Mode Squelch Requirements on expiry of the auto reset timer. The auto reset mode will be entered for the following reasons: a) on dekey of the radio. b) if the radio is selectively called. The auto reset timer will be started as soon as the selective call has been received. c) detects the correct PL for coded squelch only channels. The auto reset timer will be started as soon as the PL frequency is detected (detecting PL whilst in the auto reset mode will not restart the timer unless carrier override is specified - see below). Auto reset modes The way in which the radio will reset from the auto reset mode will depend on which of the auto reset modes has been programmed for the channel. Auto Reset disabled. The auto reset feature is disabled. Carrier Override Auto Reset. Detection of carrier within the auto reset period will reset the timer which will start again when the carrier is lost. Transmission by the radio will similarly reset the timer (e.g. PTT or Call Button operation). If the channel has PL decode enabled then auto reset will count down whilst PL is not being detected and will be reset whilst PL is detected. Carrier Independent Auto Reset. This will differ from auto reset carrier override in that the auto reset timer will not be affected by the presence of carrier or PL. On expiry of the timer the radio will auto reset. Manual Auto Reset. The radio will remain in the auto reset mode until the monitor button is tapped. Manual reset will only be available if monitor is enabled. NOTE: Exit from monitor operation will auto reset the radio even if the auto reset timer has not expired. Hence the user will be able to cause auto reset by tapping the monitor button provided monitor operation is enabled. PL OVERRIDEPL OVERRIDE Selecting this option will cause an X to be displayed in the box and when the receiver unmutes (say after 5 Tone decode of its ID), any further received PL is overridden and carrier squelch is used during the auto reset period. DISPLAYGDISPLAY This screen defines whether or not the channel number or channel alias is displayed for the channel shown in the channel option box. If an option has been selected, it will automatically be de selected when the other option is chosen. The screen contains the 4 control boxes, OK, CANCEL, NEXT and PREVIOUS. DISPLAY CHANNEL NUMBERXDISPLAY CHANNEL NUMBER Selecting this option button will cause a large an X to be displayed in the box and the channel number will be displayed when ever the channel is chosen.

Selection of this option opens the Miscellaneous file screen and enables the miscellaneous features of the radio to be selected for the channel. The screen contains the 4 control boxes, OK, CANCEL, NEXT and PREVIOUS. TALK AROUND ALLOWEDTALK AROUND ALLOWED Selecting this option will cause an X to be displayed in the box and the talk around feature will be enabled on that channel when the user presses the function button programmed with the Repeater Talk Around option. When talk Around is active, the transmit frequency of the channel will change to the receive frequency of the channel. This is intended to allow a radio to communicate directly with another radios without the need to use a repeater. RT is enabled/disable per channel. The user can not select RT on a channel if RT is disabled on that channel. An attempt to select RT on a channel which has it disabled results in the button error alert being given. On successfully selecting RT on a given channel the RT icon shall be turned on the display radio, or the Option Enabled Led shall be turned on the non-display radio. Once selected the function will remain active across channel changes. However, the function will not operate on channels for which the function is disabled but it will again operate when the radio is switch to a channel for which the function is enabled. On changing from a channel with RT enabled to one with RT disabled, the RT icon on the display radio or Option enabled led on the non-display radio shall be turned off. PRE/DE EMPHASISED5PRE/DE EMPHASISED Selecting this will cause a X to be displayed in the box. This option enables/disables audio filtering in both the transmit and receive paths. The default is not selected which is the normal requirement for tone signalling when using the internal tone generation of the radio. _SELZRHLP_AUTO_SCAN_ENABLE[SHLP_PER_CHAN_OUTPUT\THLP_CHAN_SCAN_LIST]U HELP_S5_ENC^V HLP_SIG_STD_WHLP_CALL_1_2_3`X HLP_KEY_MODEaYHLP_KEY_ENCODE_TGMbZHLP_DEKEY_ENCODE_TGMc[ HLP_SIDETALLOW CHANNEL SELECTIONALLOW CHANNEL SELECTION Selecting this option will cause an X to be displayed in the box and the channel can now be added to the channel list and it will be selectable using the up/down rocker switch. This option is not applicable to the N2 radio. Rocker Up/Down (display radio) Pressing the rocker up / down button for a time less than the rocker speed up time of 2.1 seconds, will result in a good key press alert, and the user selecting the next/previous channel, unless the current channel is the last / first channel, in which case the user will select the first / last channel respectively. Pressing either rocker up or rocker down for a time greater that the rocker speed up time, will result in the user scrolling through the available channels in ascending order for a rocker up press, or descending order for a rocker down press. The scroll rate will depend on the number of channels programmed, the higher the number of channels the faster the scroll rate. Each time the first channel is reached during scrolling, the radio will sound a good key press alert. If a channel is programmed as inhibited, then that channel will be skipped during scrolling. Once a new channel has been selected, the radio will display that new channel number, or, if an alias has been defined for that channel, then the channel alias will be displayed. Channel Select buttons (Non-display radio) On the non display radio a channel is selected by pressing one of the four option buttons 1-4 that has been programmed for channel select. AUTOMATICALLY START SCAN?AUTOMATICALLY START SCAN Selecting this option will cause an X to be displayed in the box and when ever the channel is selected the radio will enter the scan mode and use the scan list of this channel. Scanning is the ability of the radio to switch between pre-defined channels and check for activity. On a 5 Tone system, if there is activity, the radio will lock onto the channel and check for its 5 Tone call identity (ID). If its ID is detected, the user is alerted to the call and the squelch is opened. If its ID is not detected it reverts to the scan mode. PER CHANNEL OUTPUTPER CHANNEL OUTPUT Selecting this option will cause an X to be displayed in the box and any GP I/Os, programmed as per channel output, will be activated when the channel is selected. SCAN LISTSCAN LIST This option box defines which scan list is used with either the automatically start scan feature or a function button, if programmed for scan operation. S5 ENCODEES5 ENCODE Selecting this option will open the Select 5 Tone encode screen. Select 5 is a sequence of tones transmitted or received by a radio. The frequency range of these tones is from 300Hz to 3000Hz and they represent numbers from 0 to 9 and group (G) and repeat (R). If one of the six supported signalling standard is chosen, the tones will be pre-defined for frequency, duration and the time interval between the tones. The radio also offers the option of 2 User Defined standards. The screen contains the 4 control boxes, OK, CANCEL, NEXT and PREVIOUS. SIGNALLING STANDARDMSIGNALLING STANDARD This option box displays the chosen signalling format used with this channel. It can be one of the 5 signalling standards supported by the radio, or one of two user defined options. There are several 'standards' for 5 tone signalling, each of which uses a different frequencies and. tone duration . The GM950 supports all major European 5 tone signalling standards: 100ms CCIR 70ms CCIR ZVEI French ZVEI Modified ZVEI EEA In addition, two dealer defined signalling standards can be programmed to cater for special applications. Signalling is defined on a per channel basis, for optimum system integration potential. For example, channel 1 may use 100ms CCIR and channel 2 could be ZVEI. For each of the signalling standards, the group (G) and repeat tones (R) may be redefined if necessary. CALL 1 2 3CALL 1 2 3 These define the call telegram which may be sent using pre-defined function buttons when this channel is active.

DECODE SEQUENCEDECODE SEQUENCE This screen defines which of the 8 decoders will be used, with this channel, for decoding the received telegram. Any number or combination of decoders may be enabled. Note: See Decoder Definition window. AUTHORISATION5AUTHORISATION This may be enabled per channel for those channels for which a Select 5 decode sequence has been specified and applied for Select 5 channel only. The option will prevent the user from either listening to, or transmitting on the channel unless authorisation has been given. The radio will be 'authorised' when it receives an authorisation decode sequence for the channel and de-authorised when a de- authorisation (clear down) decode sequence (if specified) is received, the user changes channel, or the auto reset timer expires. Optionally it will be possible to specify that the radio is de-authorised when the auto reset timer expires or the monitor button is tapped, provided the monitor button feature is enabled. The radio may auto acknowledge the authorisation sequence and may be authorised by a group call according to the specification for the authorisation decode sequence. The same applies for de-authorisation (according to the specification for the de- authorisation decode sequence). Note: The authorisation and de authorisation decode sequences should not be programmed to be the same. The auto reset timer will not be started when the call 1 telegram is encoded for authorisation request. The auto reset timer will be started when the authorisation sequence is decoded and the radio will revert to its receive only mode when the de-authorisation sequence is decoded. The auto reset disabled option cannot be enabled on a channel with auto reset de- authorises option. When the radio is unauthorised the user may only send the call 1 telegram for the channel provided authorisation request is enabled on the channel. Any other attempt to make the radio transmit via PTT or call buttons will result in the button error tone being sounded. Authorisation request monitor. This feature allows the user to listen for an acknowledgement to the authorisation request. If this feature is enabled, after the authorisation request has been transmitted, the radio adopts auto reset squelch for a short period, defined as the Authorisation Monitor Timer. AUTO RESET DEAUTHORISESAUTO RESET DEAUTHORISES Selecting this will cause an X to be displayed in the box and on expiry of the auto reset timer the radio will be de-authorised. This will prevent the user from transmitting on the channel until a request to transmit has been authorised. PL/DPLPL/DPL Private Line (PL or CTCSS) signalling consists of a continuous sub-audible tone that is automatically transmitted when the radio is keyed. When a radio receives the correct PL tone it will open its squelch for the duration that PL is received and the user will hear audio in the speaker and when the PL tone stops being received the squelch is closed. The tones used are in the frequency range of 65Hz to 255Hz When a radio is programmed to transmit a PL code, it sends the tone code when keyed, and on PTT dekey, the tone signal is stopped, and a PL 'reverse burst' is generated. This reverse burst consists of the PL code with a 240 degree phase shift. It is sent to indicate the end of transmission to the receiving radio to reduce squelch tail. Digital Private Line (DPL) This is similar to PL, but when a radio is programmed to transmit a DPL code, it sends a digital code when keyed and on PTT dekey, the tone signal is stopped, and a DPL Turn Off Code (TOC) is sent to indicate the end of transmission to the receiving radio. Each DPL code consists of 23 unique bits, of which 12 (0 - 11) are information bits about the code and the other 11 bits (12 - 23) are generated parity bits. Inverted DPL should not normally be used but is retained for special applications such as a 'flipped' audio path or a multi-hop repeater. Inverted DPL Encode inverts all the bits in the DPL code before sending it. Inversion can be applied independently to DPL Encode and DPL Decode, i.e. there is no constraint that if inversion is applied to encode it must be applied to decode and vice versa. NOTE: PL and DPL may not be used on the same channel, i.e. PL transmit (encode) and DPL receive (decode) or vice versa. The screen contains the 4 control boxes, OK, CANCEL, NEXT and PREVIOUS. DPL TOCDPL TOC Selecting this will cause an X to be displayed in the box and a DPL Turn Off Code (TOC) is sent, by the radio when it detects PTT release, to indicate the end of transmission to the receiving radio and reduce squelch tail.

The arrows at the end of the box are used to display and define this channel. SCAN DEFINITIONS/SCAN DEFINITIONS The scan capability of a radio is its ability, when in the receive idle state on a channel which has the scan option enabled, to temporarily switch to other pre- defined channels of the active scan list. This feature enables the radio to monitor the traffic on other channels looking for a correct receive condition (PL/DPL/5 tone sequence) which will cause it to Land On the channel and unmute. The radio can enter the scan mode either by the operation of a function button, if programmed, or automatically if the Automatically Start Scan (in the channel data misc. screen) option has been enabled for the selected channel. When creating a scan list, the programmer must remember the time it takes to scan the channels in the list. Normal List: 1 2 3 4 5 6 etc. If a priority channel is specified, its number will be monitored more often and it will also be monitored when the radio has landed on another channel. Priority list: 1 2 3 1 4 5 1 6 or 1 2 1 3 1 4 1 5 1 6 etc. where 1 is the priority channel. It may be necessary to extend the first tone of a transmitted 5 tone sequence or repeat the sequence to give the scanning radio chance to switch to the appropriate channel and decode its complete ID. Scan The scan feature will cause the radio to search through a pre defined list of channels looking for a condition that will cause the radio to unmute. Whilst searching for unmute conditions, the radio is in 'active scan'. Having found the required conditions, the radio will 'land' on the channel. An option button may be programmed to start/stop scan. Note: A scan list is programmed per channel. An option button may be programmed to nuisance channel delete. The radio will support up to two RSS programmable scan lists (not user programmable) called scan A and scan B respectively. A scan list may contain up to 16 channels. Active Scan During active scan, the green LED will flashes while the radio searches through the scan lists channels for the conditions necessary for the radio to land and unmute. The channels will be scanned in the order that they appear in the scan list. Channels may be included in the scan list more than once for priority scan. Scan Modes The radio supports several modes which influence: a) the conditions required for the radio to land on a channel. b) the conditions required for the radio to resume active scan. When landed on a channel the radio enters either sweep mode or listen mode (also known as scan reset mode). Sweep mode allows a fast scan of active channels, listen mode allows conversations during scan. Carrier scan reduces the required unmute conditions of a scan lists channels to carrier squelch, and is applied in both sweep and listen mode. Listen Mode: 'listen' mode the radio will operate in the same way as auto reset carrier override except that it will use the scan reset time (programmable per scan list) instead of the auto reset time i.e. when in 'listen' mode, auto reset operation will be modified such that it will operate auto reset carrier override regardless of the auto reset mode setting for the channel and the duration of the auto reset timer will be modified to be the scan reset time (see auto reset). Note that the auto reset option to defeat PL will not be applicable to scan reset. Scan reset time is also known as scan hang time. A radio will enter 'listen' mode from active scan if it is selectively called, or after transmitting from active scan, regardless of whether 'sweep' has been specified for the scan list. Sweep Mode: Sweep mode is disabled for a given scan list by programming a sweep time of zero. Note this configuration is required to allow conversations on a pl only channel. On entering 'sweep' mode the radio will start a timer running (the sweep timer' programmable per scan list) and will recommence scanning when the unmute condition is lost or when the 'sweep timer' expires. A radio will enter sweep mode from active scan if it is not signalling squelched, and its squelch requirements are met. Carrier Squelch scan: It will be possible to specify that the radio operates carrier Squelch scan. In which case the radio will ignore the unmute condition required by the channels and instead scan for the presence of carrier. If carrier is detected the radio will 'land' on the channel and unmute (regardless of receive squelch setting). PTT during scan: Where the radio transmits during scan is determined by the scan list Scan Tx Mode, whether the radio is actively scanning or landed, and if landed whether talk back is enabled or disabled. The following table defines where the radio will transmit, for the different scan tx modes, if transmit is initiated during scan. Transmission may be initiated either by pressing the PTT or by pressing a call button. Going off-hook will also follow this table. Channel to transmit on or to suspend scan on if taken off-hook Scan tx mode During Active scan Landed, Landed Talkback disabled Talkback enabled Designated Designated Designated Landed Home channel Home Home Landed Last free Last Free Landed Landed OR !"#$%&'()*+,-./0123456789 invalid if none last busy Last Landed Landed Landed Notes: Designated scan tx mode means the transmit channel is that defined by the current scan list. Home channel scan tx mode means the channel scan was started on. Last free means the last channel found in the current scan list that was not busy (i.e. the one without carrier). If there are no free channels available then transmit will be disabled until a free channel is found. Last busy means the last channel that scan landed on. When scan is first started, i.e. before it lands on any channels, the transmit channel will default to the last selected channel. When the radio goes to the transmit channel it will first evaluate the transmit inhibit criteria. In the event that transmit is inhibited an error tone will sound whilst the button is pressed and scanning will continue. If transmit is inhibited due to forced monitor an error tone will sound whilst the button is pressed, but the radio will remain on the channel when the button is released. If transmit is allowed then the radio will stop scanning and transmit as normal. When TX finishes the radio will remain on the transmit channel as though it had landed there in the normal way. i.e. it will stay there until the reset timer expires. Hook During Scan The effect of hook on scan will depend on the per radio programming of the hook button. If programmed as disabled, then hook will have no affect on scan. The following requirements refer to hook when it is not programmed as disabled. The user can start scan when Off Hook. Going On Hook has no effect, but if the user goes off-hook during active scan, the rules applied to PTT during active scan described in the previous section shall be applied, i.e. active scan shall be suspended. The channel scan is suspended on, shall depend on the scan transmit mode programmed. If the user goes off-hook while landed on a channel (either in sweep or landed scan), and talk back is enabled, then scan will be suspended on that landed channel. The action of going back on hook, or expiry of timed hook, will cause scan to be immediately resumed. Monitor During Scan Whilst the radio is landed on a channel, pressing monitor will put the radio into monitor mode. The radio will remain on the channel while in monitor i.e. it will not recommence scanning until monitor is exited. On exit from monitor, the radio will recommence scanning immediately. Thus the user will be able to extend the time that the radio stays on a channel by monitoring and being able to manually cause the radio to recommence scanning by tapping the monitor button. A press of the monitor button while in active scan will have no effect. A button error alert will be sounded for the duration of the button press. Channel Change During Scan If an attempt is made to change channel during scan, by a rocker switch (display radio) or channel select button (non display), then the radio will exit scan go to the selected channel. Display During Scan During active scan, the radio will display the channel the radio will transmit on, unless: 1) transmission is disabled. 2) if the scan tx mode is Last Free. During transmit, the radio will display the channel the radio is transmitting on. During landed scan, when receiving, the radio will display the channel the radio is landed on. The scan icon will be on when the radio is in scan. Alerts During Scan Whenever scan is resumed, the scan start alert will be given. Scan and Busy Channel Lock Out (BCL) Carrier squelch scan will operate as normal on BCL channels. BCL rules for unmute and transmission must be applied if carrier squelch scan is disabled. Suspending scan by going off hook or pressing the monitor button will still be allowed a BCL channel but BCL rules for unmute will be applied. Other Scan features Scan LED: Whilst scanning, scanning LED indication will be given. When scan lands on a channel then the channel busy LED indication will be given whilst carrier is detected. The scanning LED indication may be disabled per scan list in which case no LED indication is given whilst the radio is actively scanning. Talk Back: Whilst the radio is 'landed' on a channel the user will optionally be able to 'talk back' by using the PTT button. Note that for channels with PL encode, PL will be encoded whilst the radio is keyed, as usual. 'talk back' whilst in 'sweep' mode will cause the radio to go into 'listen' mode on release of the PTT. Include Current Channel: Include current channel may optionally be enabled per scan list. When enabled this option will add the current radio channel ( i.e. the channel the radio is on at the point at which scan operation is started ) to the scan list. If the channel, included into the scan list via this option, is deleted through nuisance delete then it will be reinstated next time scan is started. It is not possible to specify that the channel which is included into the scan list becomes the priority channel. If the include current channel option is enabled in a scan list which has sixteen channels in it then the last channel specified in the scan list will be over written by the included channel. Auto scan: On entering a channel programmed with auto scan the radio will enter scan using the scan list assigned to the channel. Priority Channel: One of the channels in the scan list may be designated a priority channel. The programmable priority check interval determines the frequency at which the priority channel is checked both whilst the radio is actively scanning other channels or whilst it is landed on another channel. If carrier is present on the priority channel then the radio will stay on the channel and look for any other condition required for the radio to unmute (as in standard scanning). Looking for the unmute condition on anything other than a carrier squelch channel will significantly disrupt the receive audio on the channel from which the radio has to divert. The Priority Channel alert will be sounded when the radio detects the unmute condition the priority channel. The radio will be in listen mode on landing on the priority channel It is not recommended to assign tone decode to a priority channel. Any tone on the priority channel will most likely be missed because of the period between priority channel checks. All other scan channels, including the 'last free' and 'last busy' channels can be nuisance deleted. Each of the 2 available scan lists may contain up to 16 entries. The screen contains the 4 control boxes, OK, CANCEL, NEXT and PREVIOUS. SCAN LISTSSCAN LISTS This option box is used to select and display either of the 2 lists. When a list is selected, the channels in the scan list are displayed in the 16 boxes on the screen. To edit the list, select a box and change the entry. SCAN OPTIONSSCAN OPTIONS This screen defines how a scan list will operate (time spent on scan etc.) and what will happen when a channel, with scan selected, transmits, does it transmit on the frequency of the channel on which it has landed or does it transmit on the frequency of its selected channel etc. The scan option can either be selected automatically on channel selection, or by operation of a pre-programmed function button. The screen contains the 4 control boxes, OK, CANCEL, NEXT and PREVIOUS. TRANSMIT MODETRANSMIT MODE Selecting a choice from this option box defines on which frequency (channel) the radio will transmit when this scan option has been selected. The options are: Home, Last Busy, Last Free or Designated. HOME: The radio will always transmit on the channel on which scan was enabled. If the user presses the PTT during scan the radio will revert to the home channel for the duration of the call. LAST BUSY: If selected, the radio will transmit on the frequency of the channel on which it had last landed. LAST FREE: The radio scans all the available channels and when the user wishes to transmit, the radio selects the last scanned channel which was free of traffic. This type of system optimises channel usage and reduces call waiting time. DESIGNATED: This option box is used to specify the channel on which the radio will always transmit when this scan mode is active. The channel is selected by using the arrows at the end of the option box. DESIGNATED TX CHANNELDESIGNATED TX CHANNEL This option box defines the channel on which the radio transmits when the Designated option has been selected in the Transmit Mode option box. RESET (HANG)TIMERESET (HANG)TIME This option box defines the time that the radio will remain on a channel after the unmute condition is lost, prior to resuming scan. It can be set from 0 to 30 seconds, in steps of 2 seconds, using the arrows at the end of the option box.

Note this configuration is required to allow conversations on a pl only channel. On entering 'sweep' mode the radio will start a timer running (the sweep timer' is programmable per scan list) and will recommence scanning when the unmute condition is lost or when the 'sweep timer' expires. This option box defines the time allowed for the radio to remain on a scanned channel before recommencing scan. The radio will revert to scan when the unmute condition is lost or when the 'sweep timer' expires. It can be set from 0 to 30 seconds, in steps of 2 seconds, using the arrows at the end of the option box. NOTE: Setting this to 0 disables this option, and must be set to 0 to allow conversation on a PL only channel. PRIORITY CHANNELPRIORITY CHANNEL This option box displays the channel selected as the priority channel for this scan mode of operation. If the radio was active on a channel other than the priority channel, the radio, when in receive mode, still checks the priority channel for activity. Any detected traffic, on the priority channel for that radio, would cause the radio to drop its current active channel and retune to the priority channel. PRIORITY TIMEPRIORITY TIME This option box specifies how often the priority channel is checked for activity. The time can be set from 264 to 3960 seconds, in steps of 264msecs, using the arrows at the end of the option box. SCAN SWITCHESSCAN SWITCHES This screen displays other features which may be enabled to further define, how the scan mode will operate when selected. The screen contains the 4 control boxes, OK, CANCEL, NEXT and PREVIOUS. TALKBACK ALLOWEDTALKBACK ALLOWED Selecting this will cause an X to be displayed in the box and if the radio lands on a scanned channel it will unmute and allow the user to transmit on the landed channel. CARRIER SQUELCH ONLYCARRIER SQUELCH ONLY Selecting this will cause an X to be displayed in the box and the radio will ignore the unmute squelch condition required by the channel and instead, scan for a carrier. If carrier is detected, the radio will select the channel and unmute. INCLUDE CURRENT CHANNELINCLUDE CURRENT CHANNEL Selecting this will cause an X to be displayed in the box and the channel, on which scan has been enabled, is now added to the scan list. If 16 channels are already included in the scan list, then the last channel is over written by the included channel. This channel will remain part of the scan list while scan is still active, or until another channel is selected via the channel selection buttons.

GP I/O LINESDGP I/O LINES There are pins available on the accessory connector (J400) which can be controlled by the radio's microprocessor. Some are input only, some output only and some both input and output. For convenience we have called these General Purpose 1 to 6, connected as follows: Data Accessory Internal Transcrypt SmartTrunkII Standard Direction Pin Pin Accessory GP1 I 3 102-7 Open Aud Int Data Ready PTT GP2 0 4 ---- ---- ---- Ext Alarm GP3 0 8 103-7 Coded/Clear ---- ---- GP4 I 9 ---- ---- ---- Emer GP5 I/O 12 103-8 Kill ---- ---- GP6 0 ---- 102-3 Key Select ---- ---- MicPTT I ---- 102-1 PTT ---- ---- Hook I 14 ---- ---- ---- Hook Special Pins: Accessory Pin 4: Is a 12 volt output that can be used for any output function but is usually used for external alarm. Accessory Pin 3: Is an output that is shared with the serial bus data line. It can be used as a normal output, but will be overridden by serial data when the programming lead is plugged in. To restore normal general purpose output operation, the programming lead must be removed and the radio turned off, then on again. Accessory Pin 9: Is a special input that will force the radio to turn on when it is grounded. This can be used for any input function, but is usually used for emergency. Special Function: Open AUX RX audio: When this function is enabled the radio will assume that an option board has been fitted and all transmit and receive audio will be routed through the option board connector. Therefore this function should only be enabled when an option board has actually been installed,or the radio will fail to operate correctly. The functions associated with each of these lines can be set using the arrows at the end of the option boxes. Additionally the "polarity" of the line can be set using the smaller option boxes so that the line can be either active low, or active high. Input functions (available on GP1, GP4, GP5 only): Channel Steering: One or more input lines may be assigned this function to allow external equipment to select the radio's channel as a binary number. Hook: Same operation as hand held hook. PTT (Voice): Same operation as hand held PTT, but microphone used (hand held or accessory) is selectable by code plug configuration in the Per Radio screens of the RSS. PTT (Data): Keyup radio using AUX TX input. PTT (Voice & Data): Keyup radio with both AUX TX and microphone enabled. Mute audio PA: Mute all audio. Open RX audio: (like monitor) sends received signal to loudspeaker. Open AUX RX audio: Sends option board audio signal to loudspeaker. Open TX audio: (like Public Address) sends microphone signal to loudspeaker. Open AUX TX audio: Sends AUX TX signal to loudspeaker. Internal Data Ready: A falling edge on this input indicates that the internal option board wants to send some data to the microprocessor. This input will trigger an interrupt as the line may not stay low for a duration long enough to allow polling to work. This line is also used to acknowledge each byte of data sent to the board. Kill Radio: Mutes audio, locks all buttons. Call1: Same as Call1 button. Call2: Same as Call2 button. Call3: Same as Call3 button. Emergency: Same as Emergency button (but will automatically power-up the radio if assigned to GP4). Internal Option Decode: Generate an individual call alert. Output functions (available on GP2, GP3, GP5, GP6 only): Carrier Detect: Asserted when carrier is detected. PL/DPL Detect: Asserted when PL or DPL is detected. Radio Busy: Asserted when carrier is detected or radio is in TX mode. External Alarm: Asserted for a programmable time after radio is called. Per Channel Output: Allows option board or any external accessory to be switched off or on slaved to the current channel. Code/Clear Select: Output toggled by pressing Code/Clear select button. Key Select: Output pulsed for 100ms by pressing key select button. Car audio mute: Asserted with 5 second hang time whenever the radio squelches. Tone Decode: Asserted or De-asserted by 5 tone decoder. Special function (all lines) PTT Sense: This output function has two effects on radio operation: 1) Pressing the Mic PTT will NOT make the radio transmit. 2) The output line set as "PTT Sense" will be active whenever the mic PTT is pressed (see Note 2). PTT Sense is used whenever an external device (eg: a radio modem) needs to be in full control of the radio, and can allow or disallow the user's attempt to make a voice transmission. In this application, the modem would monitor the PTT Sense line and itself assert a radio input line set to "PTT Voice" to actually make the radio transmit (see note 1). NOTE 1: In this application, the audio source for the microphone must be set to use the front microphone (See "External PTT uses Accessory Microphone"). NOTE 2: If the external PTT Voice is asserted before the user presses the mic PTT, the PTT Sense ouvwutput will not follow the user's PTT activity. NOTE 3: The internal option board PTT line, used by and monitored by voice scrambler modules, will be actived by the: 1) user pressing the PTT,if this occurrs before the modem asserts PTT Voice 2) modem asserting PTT Voice, if this occurs before the user pressed the PTT In either case, the scrambler module will see the "PTT" to be active and will be in "TX" mode when transmissions actually commence. Disabled: Input lines are ignored. Output lines are held in a fixed state. Acc pin 14 is electrically the same as hand held Hook. LOW HIGHULOW HIGH This option defines the selected GP I/O line is active high or low. RX AUDIORX AUDIO Determines the type of audio signal routed to the accessory connector. Flat - Output is direct from discriminator. Filtered - Output is unattenuated, filtered RX audio. POWER UP DELAYPOWER UP DELAY This option boxes enables a time delay to be set which will allow the radio to settle, at power up, before any external inputs are accepted via the I/O lines. The time can be set from 0 - 3960ms in steps of 264ms (15 steps). S5 EMERGENCYS5 EMERGENCY The radio is capable of being programmed for emergency operating mode Emergency may be invoked by the following mechanisms: 1) If the dedicated emergency wake up I/O line is programmed for operation with a foot switch (etc), then pressing the foot switch (for the required debounce time) will ground the I/O line and cause the radio to power up in the emergency mode of operation. 2) On pressing an option button programmed as emergency for the debounce duration. If invoked via emergency wake up, Emergency operation will then take place on the channel that the radio would normally power up on had the on/off switch been pressed. If, however, an emergency revert channel has been selected then emergency operation will take place on the revert channel. EMERGENCY DEBOUNCE TIMEEMERGENCY DEBOUNCE TIME This feature is used to prevent accidental operation of the emergency button by setting a time for which the emergency button must be held pressed before the radio will recognise it as a valid key press and enter the emergency mode of operation. The time can be set from 0 to 3960 msecs, in steps of 264 msecs, using the arrows at the end of the option box. A function button may be programmed as the emergency button, or an external button may be enable using the I/O lines of the accessory connector. EMERGENCY TX, RX AND CYCLE TIMESEMERGENCY TX, RX AND CYCLE TIMES The 3 option boxes, emergency Tx, emergency Rx and emergency cycles define how the radio will operate during emergency operation. The radio can be set to transmit once and then go into receive, or switch (cycle) between transmit and receive for a specific number of cycles or until a de-activation code sequence is received. The radio can also be put into permanent cycle mode. The radio will only exit the emergency mode on receipt of a de-activation code sequence, or power is removed from the radio. The power ON/OFF switch can be programmed to be either operational or non operational during emergency operation. If the switch is non operational, then the power would have to be physically removed from the radio. The emergency Tx and Rx option boxes define how long the radio will remain in either the Tx or Rx mode when the Emergency Cycles feature has been selected. The Tx period can be set from 0 to 75 secs, in steps of 5 secs, using the arrows at the end of the option box. The Rx period can be set from 5 secs to 75 secs, in steps of 5 secs, 0 is forever, using the arrows at the end of the option box. The Cycle option box defines and displays the number of times the radio will cycle between the transmit and receive modes before going permanently into the receive mode. This feature is set using the arrows at the end of the option box. Note: The Tx to Rx ratio should be no more than 25% to avoid over heating of the transmitter. SECRET EMERGENCYzSECRET EMERGENCY Selecting this will cause an X to be displayed in the box and secret emergency will be enabled. The radio can be set to 'Secret Emergency' or 'Standard Emergency'. In secret emergency the radio will exhibit the following visual and audible characteristics: a) If the GM950 was turned off when emergency mode was started, then the radio will not light up the display or LEDs, nor will it generate alert tones or side tones: It will appear to still be turned off, even though it is in fact transmitting and receiving. b) If the radio was turned on when emergency mode was started, then the display and LEDs will not change from the 'pre-emergency' state, even if the radio is transmitting or changes channel as part of the emergency operation. In addition, if the On/Off button is non-operational, and an attempt is made to turn the radio 'Off' using the on/off button, the radio will appear to turn off, but in fact it will still be transmitting and receiving in emergency mode. This allows for the situation where the radio user is forced to turn off the radio by an attacker, but needs to still be in 'secret' emergency communications with the central dispatcher. For 'Standard Emergency' the display, LEDs and alert tones will function as in normal radio operation and they will change if the radio changes channel or transmits as part of the emergency operation. EMERGENCY ON/OFFEMERGENCY ON/OFF The On/Off button can be programmed to be operational or non-operational when in Emergency mode. If the On/Off button is operational, then when in standard emergency, it will be possible to turn the radio off (and therefore reset the emergency mode). If the On/Off button is programmed to be non-operational, then pressing On/Off button in standard emergency will have no effect. However, if the radio is in secret emergency, the On/Off button has a special effect. Selecting this will cause an X to be displayed in the box and the Power On/Off switch will be enabled. See the help text for the Secret Emergency option of more information.

This 2800Hz tone is on for 100msecs, off for 200msecs and is 10dB below nominal select 5 tone deviation. This tone is low enough in volume not to interfere with anything else received on the controllers radio. Other users on the channel would hear the tone, realise there is an emergency in progress and, hopefully, not transmit on the channel until the emergency is cancelled. EMERGENCY SQUELCHEMERGENCY SQUELCH This option box defines what is needed to unmute the receiver when the radio is in the emergency mode of operation. The choices are Carrier, PL Squelch, Closed. CARRIER: If selected, the receiver will unmute for any carrier received. PL: If selected, only received audio from a carrier that has the correct PL code will unmute the receiver. CLOSED: If selected, the receiver will be always muted. Note : 5 tone decode (if programmed) will only be required to de-activate the emergency operating mode EMERGENCY ENCODER TELEGRAMEMERGENCY ENCODER TELEGRAM This option box is used to select which 1 of the 16 possible telegrams will be sent when the radio transmits in emergency mode. No Encode is a valid option, in which case no telegram will be sent. S5 EMER REVERT CHANNELS5 EMER REVERT CHANNEL This option box is used to define a specific channel as the emergency channel. If the emergency button is activated, the radio will revert to the emergency channel and remain on it, until the emergency is cancelled.

The mic used could either be connected at the control head or via the access connector at the rear of the radio. EMERGENCY MICROPHONE GAIN]EMERGENCY MICROPHONE GAIN During emergency transmit operation, an alternative microphone gain may be used. This feature is intended to increase the microphone sensitivity and allow it to pick up conversation (etc.), over a larger area. The gain can be set from 11dB to 32dB, in steps of 3dB, using the arrows at the end of the option box. OVERVIEWOVERVIEW This window enables the programmer to display all the programmed channels, their Tx & Rx frequencies and associated encode/de-code PL/DPL tones. All these fields are editable using the mouse cursor on an option box arrow, or using the mouse cursor to high light a field and then use the keypad to enter the new value. The options in the encode/decode, PL/DPL boxes are PL, DPL, or Disabled. SEE:- Help Squelch for further information. If the Disabled option is selected that feature (Tx or Rx) will be carrier operation only. i.e. The receiver will unmute for a received carrier and no tone sequence is sent during transmit. ENCODER DEFN|ENCODER DEFN The radio will support 6 'standard' Select 5 signalling schemes :- 100ms CCIR. 70ms CCIR. ZVEI. French ZVEI. Modified ZVEI. EEA. Tones 0-9, group and repeat are supported in each standard. The signalling standard defines the tone frequency, time between tones and duration of the tones. The signalling standard used for both Select 5 encode and decode and is programmable per channel. User Defined signalling standards. In addition, it will be possible to program data for 'user-defined' signalling schemes into the radio. The radio will allow for up to 2 'user-defined' schemes. Group/Repeat Redefinition For each of the supported signalling standards the tones used for group and repeat may optionally be redefined. Each of the tones can be redefined as any one of the standard tones or any one of the single tones. A redefined group tone will cause the alternative tone to be encoded wherever a group tone is specified in an encode sequence. A redefined repeat tone will cause the alternative tone to be encoded whenever a repeat occurs in an encoded telegram, or whenever the alternative tone is decoded it will be taken to indicate tone repeat in the decoded sequence. Single Tones The radio may define up to 4 single tones. Single tones termed A, b, C and d may be reference from sequences in the same way as standard tones 0-9, G, R. For each single tone it is possible to program whether or not it can be used for single tone decode. For each single tone is it possible to define the single tones minimum and maximum duration, along with the frequency. Each single tone can have a frequency in the range 300-3000Hz. ENCODER DEFN: This window contains 3 option screens, Encoder Sequences, Multicall Definitions and Telegram Definitions. These screens are used to define all the different methods of select 5 signalling which the radio is capable of either transmitting or receiving, and under what circumstances they are used. Select 5 is a sequence of tones transmitted or received by a radio. The frequency range of these tones is from 300Hz to 3000Hz and they represent numbers from 0 to 9 and group (G) and repeat (R). (for definitions of group codes see decode definitions). Single tones may also be dealer defined and used within sequences or on their own. There are 4 pre-defined single tones in the radio, they are: A, b, C and d. If one of the six supported signalling standard is chosen, the tones will be pre-defined for frequency, duration and the time interval between the tones. The radio also offers the option of 2 User Defined standards. A sequence acts in the same manner as a telephone number and under normal operation a select 5 Telegram, is used to address a specific radio. When a radio receives its code, its user is alerted to the call by a series of 5 rapid alert tones and the radio unmutes. In order to make a selective call, the radio can be programmed to send one, two or three 5 tone sequences in rapid succession, e.g.: 12345, or 12345 34251, or 12345 34251 87589 Whatever the number and combination of sequences, this is known as a telegram. Up to 16 telegrams may be programmed into the radio, each being any combination of the 16 encode sequences. Telegrams may be sent in a variety of ways, such as pressing the PTT, or one of the programmable function buttons which has set to be a call button. It is also possible to have an external call button. Telegrams are also used to define the message sent by the Auto-Acknowledge and Call Forward features. It is also possible for groups of users to share a group number as well as having an individual number. If a sequence has identical sequential digits, the radio will automatically change some ofthe digits for repeat tones. e.g. 1 2 3 3 3 5. This will be changed by the radio to: 1 2 3 R 3 5. This process is used to prevent code corruption during decoding. ENCODER SEQUENCESENCODER SEQUENCES There are 16. Note: Sequence 1 is used with the multicall 1 option and Sequence 2 is used with multicall2. Each sequence is defined using 3 option boxes, the actual Sequence Box, an Extended First Tone (EFT) box and a PreTime box. The 7 entries in the sequence box are entered and edited using the mouse cursor and the keypad. Valid entries are 0 - 9, G, A, b, C and d. EFT (ms): Operational requirements may mean that the first tone of the sequence has to be extended in duration. If a radio is scanning, it will need time to scan the channels prior to scanning the one on which it has received the call, with the possibility that it may only receive part of its decode sequence. If the list is short, extending the first tone by an appropriate time may overcome this problem, otherwise repeat tone sequences will be required. The duration of the first tone can be set between 0ms to 2104ms in steps of 8ms using the arrows at the end of the option box. Pre-Time: The time set in this option box is used in repeater operations to allow the repeater to reach its operating power output before the radio sends its encode sequences. The setting can be between 0 and 2104ms in steps of 8ms, set using the arrows at the end of the option box. MULTICALL DEFINITIONSLMULTICALL DEFINITIONS The radio supports 2 multicall sequences known as multicall 1 Address and multicall 2 Status. The radio allows up to 3 digits (variable) to be altered by the user. Each multicall sequence consists of a base encode sequence and programmable configuration to specify which digits in that base encode sequence are variable. Encode sequence 1 is the base sequence for Multicall 1 and encode sequence 2 is the base sequence for Multicall 2 It is not possible for entered variable digits to affect the length of the sequence. If the initial digit in the base sequence is not within the range that the user may select then when the user first presses the rocker switch this value will be correct to a valid digit. A programmable multicall configuration determines the acceptable digits which the user may enter. The Select 5 sequence can then be sent as part of an auto acknowledge Telegram 1, or as part of the PTT or call telegram to selectively call other radios. The user may enter multicall 1 or 2 by direct button access. On entry to Multicall the appropriate multicall icon, either a musical note symbol for muticall 1, or an S for multicall 2, will be displayed, as well as the right most multicall position icon. This indicates that the right most multicall digit is active. For the currently active digit, using the up scroll button will scroll the allowed digits (within the range 0-9, G, A, b, C, d) through this position. For the currently active digit, using the down scroll button will scroll the allowed digits (within the range 0-9, G, A, b, C, d) through this position. Whilst in multicall, for multicall configurations with more than 1 variable digit, a press of the multicall button will change the active digit. For each digit position defined, the user shall be able to program, via the RSS an upper and lower limit, allowing multicall selection to choose from a range of sequential digits. MULTICALL DEFINITIONS WINDOW: This screen is used to optimise the pre-defined multicall sequences to user operational requirements. Multicalls (2) are selectable using the arrows on the multicall display box. Address (Multicall 1) Usually, sequences are fixed, and are dealer defined by the RSS. This is not a problem if there is a need to call only one, or a few addresses (numbers), such as the central dispatcher, or group call. In order to provide the user with the capability to make calls to a larger number of addresses, the N3 model is equipped with 'Multicall 1,000'. This function allows the user to alter the numbers of one of the encode sequences. As up to 3 of the numbers may be altered, it is possible to call up to 1,000 other users (000 to 999). The addresses are selected by putting the radio into Address Mode and using the up/down buttons to vary the active digit then pressing the Address Mode button again to change the active digit (indicted by the small triangle icon). One of the function buttons can be programmed as 'Call 1, 2 or 3' and this button may activate a telegram containing the variable sequence (Seq 1). Once the desired address has been selected, pressing this button or the PTT, will send a call to the appropriate radio. For each of the three user variable digits, a selection range and lockout digit may be specified (e.g.: user is only allowed to select from 0 to 6, and digit 4 is skipped). This enables the possible call ranges to be limited, to restrict an individuals ability to call radios outside his own 'work group'. Single tones and the Group tone may also be user selected to be included in the variable sequence, to allow the GM950 to be integrated into a wide range of existing 5 tone systems. Status (Multicall 2) Multicall 2, when enabled an S will be displayed, can be used to send a 'Status' sequence. Rather than having to establish voice contact with the central dispatcher, the user can simply select the appropriate Status message number (by putting the radio into Status Mode, and changing the digits in a similar manner to altering the Address). The 5 tone telegram containing the Status number can be sent by pressing the appropriate call button or PTT. Since the Status function can also be used to vary up to 3 digits in the 5 tone sequence, it may also be used for other functions, such as selection of the different numbers needed to access one of several repeaters. MULTICALL LIST MULTICALL LIST This box displays the multicall to which all the information contained on this screen applies. The arrows at each end of the box are used to scroll through (up or down) the list of available multicalls. There are only 2 multicall available.

Clicking the mouse cursor selects a digit and up to 3 digits (any 3) may be selected. An X will be displayed in the digit box after selection. Once a variable digit has been selected, it is then user definable using the buttons on the radio control head (but only for digits where Xs are present in the base sequence). %FIRST, SECOND AND THIRD VARIABLE TONE$FIRST, SECOND AND THIRD VARIABLE TONE The option boxes From Tone and To Tone are used to define what digits, from the range 0 - 9, G, A, b, C and d, the user is allowed to enter in the 3 variable positions. e.g: From 0 to 4 limits selection to 0, 1, 2, 3 or 4 for that digit. LOCKOUT TONELOCKOUT TONE This option box defines a tone which the operator is not allowed to use in a variable position. Disabled is a valid choice in this option box. ENCODER TELEGRAMSENCODER TELEGRAMS Up to 16 telegrams can be defined in this window. A telegram can contain up to 3 sequences. The sequence is chosen using the arrows at the end of each option box. The sequences are defined in the Encoder Sequences screen of the Encoder Definitions window. DECODER DEFINITIONSDECODER DEFINITIONS On a per channel basis up to 8 parallel decoders may be enabled. Each decoder is configurable as described in the following sections. This very powerful tool provides extreme flexibility by allowing dealers to programme radios to more closely match end user requirements. Whilst parallel decoders allow the number of decode functions to be increased, it is of course still easy to 'set up' a radio with simple operational parameters for less demanding customers. Each decoder may be set to generate audible beeps and visual alerts (flashing LEDs) for Individual Call and Group Calls, and may trigger an external alarm relay. Additionally, on N3 models, each decoder may generate an ID Decode (Caller Identity) number which will be displayed. Decode sequences A decode sequence may consist of up to 7 tones. Any of the standard signalling tones (0- 9, G, A, b, C and d) may be specified in the sequence. If the same tone occurs consecutively in the sequence that the decoder is looking for then it will expect a repeat tone to occur in the sequence that it receives. A maximum of 16 decode sequences may be defined. Select 5 decode: individual call On receiving an individual call, any of the following individual call user indications may be programmed. Decode Alert When individually called a Select 5 individual call alert can be programmed to be given. This alert can be programmed to be enabled or disabled for each defined individual call. Call Reminder Alert When individually called a Select 5 individual call reminder alert may be given at (fixed) 15 second intervals after the individual call decode alert. The alert will be cancelled by any user activity. This alert can be programmed to be enabled/ disabled for each defined individual call. Decode Led When individually called a Select 5 individual call decode led may be given (the indication given is very quick and may be missed, but it will be followed by the decode LED reminder indication if programmed). Call Reminder Led When individually called, the Select 5 individual call reminder led flashes continuously until stopped by any user activity. Select 5 decode: ID decode The purpose of this feature is to identify the calling party by displaying one, two or three digits from their radio's ID. Which digits to display from the incoming sequence must be programmed via the RSS. The displayed digits will appear flashing on the right-hand side to the display until cleared by any button press or channel change. When single tones J, K, L, and M are decoded they will be displayed as A, b, C, d respectively. If the radio is in variable sequence (multicall) entry mode when decode display is activated then it will automatically exit that mode. Decode telegram configurations The radio shall support the following decode telegram configurations where: Radio A is the calling radio. Radio B is the called radio. T = any tone set by RSS. X = any tone. A = any tone from ID of calling radio. B = any tone from ID of called radio. Any 1,2 or 3 digits can be chosen for display. The following examples use the last three digits. Single sequence. e.g.. TTAAA radio displays AAA. Double sequence (ID second) or Called - Calling: e.g.. TTBBB XXAAA radio displays AAA. Note: radio will also decode TTBBB alone with no display. Double sequence(ID first) - Calling-Called. e.g.. XXAAA, TTBBB. TTAAA, TTBBB, radio decodes and displays AAA. TTBBB radio decodes but no display. Triple sequence - Called-Called-Calling. e.g. TTBBB, TTBBB, XXAAA, radio decodes and displays AAA. Sequence Time-out Timer If a decoder telegram is a combination of multiple sequences, then there must be a delay time of 500msecs between successive sequences. Select 5 decode: group call Two types of group call are supported, standard or expanded per group block, in either case a seven bit group mask indicates group positions where group tones are allowed in the sequence. For standard group call, a group position will be a position in the decode sequence at which the radio will accept either the group tone or the individual tone. After detection of a valid group tone all subsequent tones of the sequence must also be group tones for the sequence to be recognised as a call for the radio. Note that consecutive group tones will be subject to auto R insertion. For expanded group call, a group position will be a position at which the radio will accept either the group tone or the individual tone. Group tones will not be accepted in positions other than group positions. Once the radio has received a group call the group call reminder LED indication may be programmed to be given. This LED indication starts after the radio selectively called LED indication. The reminder indication is cancelled if one of the radio buttons is pressed. When the radio receives a group call it may give the group call alert. This alert may be disabled or enabled. Select 5 decode: auto acknowledge features It is possible for the radio to transmit both an AA and CF telegrams in response to a individual decode. If both AA and CF telegrams are transmitted then the AA telegram will be encoded first. All three features support acknowledge delay, and acknowledge revert Channel as described below. Auto Acknowledge The acknowledge telegram can be programmed to always be sent in reply to an individual call. The Decoder Definitions Window: The file screens in this window define what action(s) the radio will take when it receives different tone sequences. SEQ. + MASKSSEQ. + MASKS This screen not only defines the radios own decode and group decode sequences, but also defines which digits (up to 3) of an incoming sequence will be displayed. This allows a user to see who is calling, or if the call was missed, who called, so the call may be returned. Individual Call Each of the 8 parallel decoders may be, optionally, set to cause the radio to trigger the Individual Call alert on receipt of the appropriate call. This is indicated to the user that by a series of audible tones and a flashing yellow LED. Group Call One key strength of any two-way radio, especially the less complex PL (CTCSS) radios, is the ability to have group, or Conference calls. Each person can hear all transmissions, conversations, and are able to take part in the discussion, transmit. For each of the 8 decoders, it is possible to specify which digit positions in the received 5 tone sequence can be Group digits. This means that if a Group tone is received in that position rather than the usual numbers tone, the radio will still recognise and decode the call. The radio will then generate a Group Call alert (see user manual). The GM950 supports both standard and expanded group call decode. Standard: Radio ID is: 1 2 3 4 5. Group digits: 1 2 3 G G. Radio will respond to: 12345 (Individual Call). 123GG (Group of up to 100 radios). 1234G (Sub-Group of 10 radios). Expanded: Radio ID is: 1 2 3 4 5. Group digits: 1 G 3 4 G. Radio will respond to: 12345 (Individual Call). 1G34G (Group of up to 100 radios). 1234G (Sub-Group of 10 radios). The screen contains the 4 control boxes, OK, CANCEL, NEXT and PREVIOUS.

The mouse cursor is used to select up to 3 digits (any 3) which will be displayed when the tone sequence is received. An X will be displayed in the digit box after selection. The digits specified by the ID decode mask are copied into the multicall 1 sequence for the call back feature. There are three ways that 5 tone systems can be set up to provide the ID Decode feature. The first two ways require that two sequences are sent to the radio as a telegram. One sequence has details of the calling radio, and the other sequence has details of the radio being called. e.g.: Caller ID is 345: 12345 12367 Calling Radio Identity followed by Radio to be Called. 12367 12345 Radio to be Called, followed by Calling Party Identity. In either case, the GM950 that has been called will display the number 345. The third method is to use a single sequence, extended from 5 to 7 tones. E.g. 1234567 Calling Radio Identity is 67, displayed on called radio. The selected positions also define which digits will be used for call back. GROUP ALERT MASK'GROUP ALERT MASK This option displays 7 small boxes which represent the 7 available digits that may be used in a tone sequence. The mouse cursor is used to select the positions of the group digits which will define the group sequence as either a standard or expanded group call. An X will be displayed in the digit box after selection. For each of the 8 decoders, it is possible to specify which digit positions in the received 5 tone sequence can be Group digits. This means that if a Group tone is received in that position rather than the usual numbers tone, the radio will still recognise and decode the call. The radio will then generate a Group Call alert (see user manual). The GM950 supports both standard and expanded group call decode. Standard: Radio ID is: 1 2 3 4 5 Group digits: 1 2 3 G G Radio will respond to: 12345 (Individual Call). 123GG (Group of up to 100 radios). 1234G (Sub-Group of 10 radios).

The screen contains the 4 control boxes, OK, CANCEL, NEXT and PREVIOUS. SEQ. OPTIONSSEQ. OPTIONS This screen defines both the actions the radio will take on receipt of the particular decode sequence and also sets the time duration for the first tone, if the received sequence has an extended first tone (EFT). Assert output control line On select 5 decode it is possible to program a decoder to assert an I/O line programmed for select 5 decode output control. De-assert output control On select 5 decode it is possible to program a decoder to de-assert an I/O line programmed for select 5 decode output control. Stun On select 5 decode it is possible to program a decoder to "stun" the radio. All attempts at user activity on a stunned radio, accept turning the radio on/off will be ignored. The radio display shall be frozen. The radio will not respond to any received signalling, apart from the unstun decode sequence. A stunned radio shall remain muted. On turning the radio off and back on again, the radio will remain stunned on the channel on which it was stunned, it will give a two tone alert and if it is a display model, 3 horizontal bars will be displayed. unstun It is possible to program a decoder to unstun the radio. If a stunned radio decodes the unstun decode sequence, normal operation shall be resumed. NOTE: The radio may also be unstunned by reprogramming the radio using the RSS. The screen contains the 4 control boxes, OK, CANCEL, NEXT and PREVIOUS. EXTENDED FIRST TONEEXTENDED FIRST TONE This option box sets the time duration of the first tone of the received sequence. If a transmitted sequence has an extended first tone, the receivers decoders must know what the duration is, otherwise the sequence would be corrupted on decode. The length of the tone would not be of the correct duration for the standard used (CCIR, EEA, ZVEI etc). The time can be set between 0ms and 2040ms in steps of 8ms. DECODE FUNCTIONDECODE FUNCTION A decoder may be programmed that upon receiving a specific tone sequence, the radio will carry out certain operations. The choices available in this option box are Disabled, Auto Reset and Clear Down. DISABLED: This choice disables the Decode Function option box. AUTO RESET START: The radio can be programmed to enter auto reset operation (open squelch) on receipt of a specific tone sequence, such as for Authorisation. Auto reset must be enabled on the channel for this option to be selected. CLEAR DOWN: On receiving the correct sequence the radio will stop auto reset and go into receiver squelch operation. This feature is used to De-authorise the radio. Auto reset must be enabled on the channel for this option to be selected. STUN / UNSTUNSTUN / UNSTUN This feature is used by a controller to operationally disable, or enable a radio. It is possible to send out a tone sequence which when received by the radio, it will cause the radio to cease operating. The radio will power up, but give a 2 tone sequence and all button operations will be disabled. This feature can be used if the radio is stolen, or the user hasnt paid a bill etc. On receipt of the correct sequence the radio will unstun and return to its operational state prior to being stunned. If an Unstun sequence is not specified, the radio can only be recover using the RSS. The stun feature can be disabled using the RSS. EMERGENCY EXITEMERGENCY EXIT Choosing this option will cause an X to be displayed in the box and when the radio receives the correct decode sequence during the emergency operating mode, the radio will revert to its normal operating mode. The only other way of resetting the radio from the emergency operating mode is to remove the power from the radio. The power on /off switch is disabled in emergency operation, so power must be removed by disconnection at source. OUTPUT CONTROL LINElOUTPUT CONTROL LINE It is possible to programme an I/O line to go either high or low (assert or de-assert) when a specific 5 tone sequence has been received. As an example it may be a requirement that on receiving an emergency sequence a tape recorder is activated to record all conversations. The option box choices are Disabled, Assert or De-Assert. AUTO ACKNOWLEDGESuAUTO ACKNOWLEDGES It is possible to define a tone sequence which will be automatically transmitted on receipt of a decoded sequence. Auto Ack confirms that the users radio is in the coverage area and is powered on, the user may be away from the vehicle. The choices in this option box are either Disabled, or selecting 1 from a maximum of 8 Auto Ack telegrams. CALL FORWARD ACKNOWLEDGE<CALL FORWARD ACKNOWLEDGE It is possible to define a telegram which will be automatically transmitted on receipt of a decoded sequence. This sequence can alert a user to a call, when away from the vehicle, by activating a pager ,or if carried, a portable radio. Its normal use is to confirm to the controller that the users radio is in the coverage area and is powered on. The choices in this option box are either Disabled, or selecting 1 from a maximum of 8 Auto Ack telegrams. If this feature is used, a function button must be programmed with this option.

As a received sequence can contain up to 2 concatenated telegrams the digits can be selected from either the first or second telegram, or from a single telegram. The screen contains the 4 control boxes, OK, CANCEL, NEXT and PREVIOUS. ID DECODE OPTIONSID DECODE OPTIONS The purpose of this feature is to define which received tone sequence will have its digits displayed (up to 3 digits). The choices are : Single - If only one sequence is being received, then digits from this sequence will be displayed. First - If two sequences are being received, then digits from the first sequence will be displayed. Second - If two sequences are being received, then digits from the second sequence will be displayed. CALL BACK3CALL BACK Call back allows the radio to return a call to a calling unit, after the auto reset timer has expired and when the call has not been answered, using digits defined in the 'Decode Display' mask. This feature will be used in conjunction with ID decode, but is also operational on the non- display (N2) models.(The user will not know which number is being called.) Call back will operate by taking the caller's ID out of the decode buffer and copying it into the Multicall 1 buffer. In this way call back will operate as though the user had typed in the required ID. If the radio is in Multicall entry mode when call back is activated, it will automatically exit that mode. The received calling sequence must be the same length as the base encode sequence if the substitution is to take place. GROUP OPTIONSGROUP OPTIONS Two types of group call are supported, standard or expanded per group block, in either case a seven bit group mask indicates group positions where group tones are allowed in the sequence. Standard: Radio ID is: 1 2 3 4 5. Group digits: 1 2 3 G G. Radio will respond to: 12345 (Individual Call). 123GG (Group of up to 100 radios). 1234G (Sub-Group of 10 radios). Expanded: Radio ID is: 1 2 3 4 5 Group digits: 1 G 3 4 G Radio will respond to: 12345 (Individual Call) 1G34G (Group of up to 100 radios) 1234G (Sub-Group of 10 radios) STANDARD GROUP CALL: For standard group call, a group position will be a position in the decode sequence at which the radio will accept either the group tone or the individual tone. After detection of a valid group tone all subsequent tones of the sequence must also be group tones for the sequence to be recognised as a call for the radio. Note that consecutive group tones will be subject to auto R insertion. When the radio receives a group call it may give the group call alert. This alert may be disabled or enabled. EXPANDED GROUP CALL: For expanded group calls, a group position will be a position at which the radio will accept either the group tone or the individual tone. Group tones will not be accepted in positions other than group positions. This allows more sub groups to be implemented. Note that consecutive group tones will be subject to auto R insertion. Once the radio has received a group call the group call reminder LED indication may be programmed to be given. This LED indication starts after the radio selectively called LED indication. The reminder indication is cancelled if one of the radio buttons is pressed. When the radio receives a group call it may give the group call alert. This alert may be disabled or enabled. GROUP TONEGROUP TONE This option box defines the group tone. It can be any of the tones 0 - 9 or A, b, C or d.

The Call Alert Decode feature provides the capability for the radio to respond to the Call Alert message transmitted from the dispatcher/base. Call Alert Encoding is a Call List feature. If you wish to use ANY call list position to send Call Alerts, then check the Call Alert Enable check box. Otherwise the user will not be able to select Call Alert (usually displayed as 'CA') using the Select button on the front of the radio. VOICE SELCALL ENCODEVOICE SELCALL ENCODE Voice Selective Call is used to either make a conversation with the receiving radio unit or make an announcement to an individual radio or a group of radios. Majority of Voice Selective Call usage is in transmission between dispatcher and a single radio. Voice Selective Call Decode provides the capability of receiving Voice Selective Call transmission. Voice Selcall Encoding is a Call List feature. If you wish to use ANY call list position to send Voice Selcalls, then check the Selcall Enable check box. Otherwise, the user will not be able to select Voice Selcall (usually displayed as 'SC') using the Select button on the front of the radio. RADIO CHECKRADIO CHECK This feature allows a dispatcher to determine if a radio is on the air and functioning without disturbing the user of that radio. It can be used as a routine preventive maintenance check, or as a specific action when the dispatcher has some reason to doubt the availability of a given radio. In essence, the function is like a Call Alert, except there is no alerting of the radio user. Radio Check Encoding is a Call List feature. If you wish to use ANY call list position to send Radio Checks, then check the Radio Check Enable check box. Otherwise, the user will not be able to select Radio Check (usually displayed as 'CH') using the Select button on the front of the radio. CALL ALERT WITH VOICESCALL ALERT WITH VOICE Same as call alert, except that it allow normal conversion in call mode. It is different from Sel Call in that it has the call reminder capability. CA/voice can be considered as a functionality between Call Alert and voice Selective Call. Call Alert with Voice is also a Call List feature. If you wish to use ANY call list position to send Call Alerts with Voice, then check the Call Alert with Voice check box. Otherwise the user will not be able to select Call Alert with Voice (usually displayed as 'CAS') using the Select button on the front of the radio. NUMBER OF RETRIESNUMBER OF RETRIES This field defines how many retries will call alert, call alert with voice or radio check perform if the radio did not receives any acknowledge. Accepted value is an integer range from 0 to 15. ` K5 K5 K5 K5  K5 K5 K5 K5T K5 K5 K5 K59 K5K5gK5K5K5K5K5K5cK5K5K5K5K5K5K5K5K5K5K5K5ACKNOWLEDGE DISPLAY TIMEDACKNOWLEDGE DISPLAY TIME When the radio receives an acknowledge message of Call Alert, call alert with voice or Radio Check, the radio will display an "A" to indicate the acknowledge.

INDIVIDUAL REMINDER TIMEINDIVIDUAL REMINDER TIME When a radio receives a call alert or emergency alarm, a reminder alert may be given. This field define the time interval between the alerts and can be set from 2 sec to 32 sec in step of 2 sec. ID DISPLAY TIMEID DISPLAY TIME When a PTT ID targeted to the received radio is received, the ID of the transmitting radio will be displayed on the LCD. This field define the duration of the ID display. It can be set from 2 sec to 32 sec in step of 2 sec. MDC EMERGENCYMDC EMERGENCY In Public Safety, and other applications where radio is used at least in part as a security tool, Emergency Alarm is typically used to inform dispatch of a life threatening situation. The feature must be easy to generate at the subscriber unit, reliable, and must be certain of attracting immediate attention at the dispatch equipment. There will be two types of emergency operations co-exist on the radio, basically differentiated by the signalling which is used to generated the emergency call: Select 5 emergency and MDC emergency, determined by the encoder signalling type of the channel at which the emergency is activated. Both operations are mostly the same, this section will dedicated to the MDC Emergency.

Note : It is important to have a emergency switch connected to the radio when the codeplug is changed. If not the radio will immediately go into the Emergency sequence and turn on the transmitter. LONG KEY PRESS DURATIONLONG KEY PRESS DURATION This feature is used to prevent accidental operation of the emergency button by setting a time for which the emergency button must be held pressed before the radio will recognise it as a valid key press and enter the emergency mode of operation. The time can be set from 0 to 3960 msecs, in steps of 264 ms. A function button may be programmed as the emergency button, or an external button may be enable using the I/O lines of the accessory connector. EMERGENCY TX, RX AND CYCLE TIMESEMERGENCY TX, RX AND CYCLE TIMES The 3 option boxes, emergency Tx, emergency Rx and emergency cycles define how the radio will operate during emergency operation. The radio can be set to transmit once and then go into receive, or switch (cycle) between transmit and receive for a specific number of cycles. The radio can also be put into permanent cycle mode. The radio will only exit the emergency mode when the power is removed from the radio or until the expiration of limited number of Tx/Rx cycles. The power ON/OFF switch can be programmed to be either operational or non operational during emergency operation. If the switch is non operational, then the power would have to be physically removed from the radio in order to terminate emergency mode. The emergency Tx and Rx option boxes define how long the radio will remain in either the Tx or Rx mode when the Emergency Cycles feature has been selected. The Tx period can be set from 0 to 75 secs, in steps of 5 secs. The Rx period can be set from 5 secs to 75 secs, in steps of 5 secs, 0 is forever. The Cycle combo box defines and displays the number of times the radio will cycle between the transmit and receive modes. Note: The Tx to Rx ratio should be no more than 25% to avoid over heating of the transmitter. POLITE TRIESWPOLITE TRIES The MDC signalling is a multiple user environment which requires that the utilization of the communication channel be properly managed. Several users may want to transmit at the same time on the channel and this will cause severe communication clashes if not properly managed. Regulations must be implemented to ensure that signalling does not interfere with voice transmission. The system requires a channel protocol to manage the communication channel. The channel protocol described here has the following system features : Polite Transmission. This transmission type requires that the channel is clear before transmission is permitted. A channel is clear if there is no any carrier in the channel. Additionally, if the Tx Allowed in per channel block is set to "ALWAYS", polite transmission won't be applied. Impolite Transmission. This transmission type does not check whether the channel is clear before transmission. This field defines the number of polite tries required for Emergency Alarm. Possible values are from 0 to 255. Value of 255 means infinite tries. IMPOLITE TRIESIMPOLITE TRIES This field defines the number of impolite tries required for Emergency Alarm. Possible values are from 0 to 255. Value of 255 means infinite tries. POLITE FIRST POLITE FIRST This yes/no parameter is programmable in the codeplug and defines whether Emergency Alarm is to be transmitted as polite transmission before impolite transmission. or vice versa. If this option is enabled, the emergency will polite trasnsmit first. ON/OFF ENABLERON/OFF ENABLE The On/Off button can be programmed to be operational or non-operational when in Emergency mode. If the On/Off button is operational, then when in standard emergency, it will be possible to turn the radio off (and therefore reset the emergency mode). If the On/Off button is programmed to be non-operational, then pressing On/Off button in standard emergency will have no effect. However, if the radio is in secret emergency, the On/Off button has a special effect. Selecting this will cause an X to be displayed in the box and the Power On/Off switch will be enabled. SILENT EMERGENCY}SILENT EMERGENCY Selecting this will cause an X to be displayed in the box and secret emergency will be enabled. The radio can be set to 'Secret Emergency' or 'Standard Emergency'. In secret emergency the radio will exhibit the following visual and audible characteristics: a) If the radio was turned off when emergency mode was started, then the radio will not light up the display or LEDs, nor will it generate alert tones or side tones: It will appear to still be turned off, even though it is in fact transmitting and receiving. b) If the radio was turned on when emergency mode was started, then the display and LEDs will not change from the 'pre-emergency' state, even if the radio is transmitting or changes channel as part of the emergency operation. In addition, if the On/Off button is non-operational, and an attempt is made to turn the radio 'Off' using the on/off button, the radio will appear to turn off, but in fact it will still be transmitting and receiving in emergency mode. This allows for the situation where the radio user is forced to turn off the radio by an attacker, but needs to still be in 'secret' emergency communications with the central dispatcher. For 'Standard Emergency' the display, LEDs and alert tones will function as in normal radio operation and they will change if the radio changes channel or transmits as part of the emergency operation. 3tHLP_MDC_EMER_ACT_ALERTHLP_MDC_EMER_REVERT_RETHLP_MDC_ACK_DELAYHLP_MDC_QUEUE_REJECTHLP_MDC_EMER_SQUELCHHLP_MDC_EMER_RVT_CHNHLP_MDC_EMER_MIC_SOURCEHLP_MDC_EMER_MIC_GAINldHEEMERGENCY ACKNOWLEDGE ALERTEMERGENCY ACKNOWLEDGE ALERT When the acknowledgement to Emergency is received, the Emergency Acknowledge alert will be generated.

The range of the Acknowledge Delay Duration will be 0 ms to 2040 ms in 8 ms steps. This option is used by the console radio only. QUEUE REJECT TIMEQUEUE REJECT TIME This field defines the time period in which within this period, the radio will reject the same emergency call already in the queue. The accepted range is from 0 to 2673 s in 11s step. EMERGENCY SQUELCHEMERGENCY SQUELCH This option box defines what is needed to unmute the receiver when the radio is in the emergency mode of operation. The choices are Carrier, PL Squelch, Closed. This will not applied to the console radio. CARRIER: If selected, the receiver will unmute for any carrier received. PL: If selected, only received audio from a carrier that has the correct PL code will unmute the receiver. CLOSED: If selected, the receiver will be always muted. MDC EMER REVERT CHANNEL MDC EMER REVERT CHANNEL This option box is used to define a specific channel as the emergency channel. If the emergency button is activated, the radio will revert to the emergency channel and remain on it, until the emergency is cancelled. Note: 0 (zero) entry is disabled.

The mic used could either be connected at the control head or via the access connector at the rear of the radio. EMERGENCY MIC. GAINEMERGENCY MIC. GAIN During emergency transmit operation, an alternative microphone gain may be used. This feature is intended to increase the microphone sensitivity and allow it to pick up conversation (etc.), over a larger area. The gain can be set from 11dB to 32dB, in steps of 3dB, using the arrows at the end of the option box. If the setting is 0dB, normal gain will be used. GENERALGENERAL This page defined the general options of MDC signalling like PID, VID; determines the radio is act as console or client. PIDPID MDC1200 requires that each radio have a unique four digit ID number. The default is the last four digits of the radio serial number. The range is from 0001 to DEEE. VIDVID The MDC1200 Variable id is a three hex digit number common to a group of radios and ranges from 000 to EEE. It was usually used in group call. CONSOLECONSOLE One radio in the system should be designated as the Console Radio (Control Unit). The purpose of this radio is to acknowledge the receiving Emergency Alert. If this field is enabled, the radio will respond to an Emergency with an acknowledge transmission. Since non-display model do not have a display to show the unit ID of the transmitting radio, they are not allowed as Console radios. ACKNOWLEDEACKNOWLEDE Systems that use Call Alert require that the radio acknowledge (ACK) that the Call Alert has been received. The radio normally will not acknowledge "group calls". Other MDC call that need an Ack are Call Alert with voice, Radio check and emergency. ACK DELAYACK DELAY ACK Delay is the delay time the radio will wait before start the transmission of Acknowledge message. The range can be from 0 to 2079 ms in 33 ms steps. MDC ENCODEMDC ENCODE This page defined all the options that related to encoding MDC signal. For examples, PTT ID, Keyup Mode, Sidetone/Short sidetone, PTT Pretime, Preamble Bit Sync. Number, Polite Patient time, Fixed Retry Wait time and M constant. PTT PRETIMENPTT PRETIME The PTT pretime is the delay from the start of transmit (when the operator pushes PTT) to when the data signalling begins. This delay is required in order to allow the radio to completely open the communications path through repeaters or other system components. The range can be from 0 to 4080 ms in 16 ms steps.

In cases where the RF carrier is due to an interfering signal produced by other system and is not users trying to communicate on the channel, the polite transmission will never be executed as long as the interfering signal is present on the channel. The Limited Patience Timer feature is used to convert the polite transmission to impolite transmission after the interfering signal have existed for a predefined period of time. The range can be from 0 to 268 secs in 1 sec steps. FIXED RETRY WAIT TIMEFIXED RETRY WAIT TIME When Call Alert, Call Alert with voice, Radio Check or Emergency is activated by the operator, the radio expects an acknowledge from the base station. If no acknowledge is received then the radio will repeat the MDC message after a delay. The radio always waits a random time greater than twice the Pretime. The additional time is the Fixed Retry Wait time. Fixed Retry Wait is the time the radio waits between emergency tries. The range can be from 0 ms to 16830 ms in 66 ms steps.

PTT KEYUP MODEPTT KEYUP MODE If you want your unit ID to be sent on each Push-to-talk (PTT), then this field will defined how the ID is sent following the critiria EVERY PTT or ONCE. ID id sent at the press of PTT. If you choose "NONE", then the ID will not be sent during PTT. TRAILING PTT IDTRAILING PTT ID This field enable/disable the trailing PTT ID. When enable, ID is transmitted trailing the voice transmission. There is one Trailing PTT ID option per Signalling content. PTT SIDETONEnPTT SIDETONE PTT sidetones are used when PTT ID is activated. Sidetones are heard through the speaker when the operator first presses the PTT. They are used to tell the operator that he cannot speak until the ID has been transmitted. There are two sidetones available in the Radio. The PTT ID Sidetone is a continuous tone heard from PTT until the ID has been sent. The second tone, PTT Short Sidetone, is a short beep after the ID has been sent. Both tell the operator when he is permitted to speak into the microphone. One, both or no Sidetones maybe activated. This check box is set to enable the sidetones. PTT SHORT SIDETONE}PTT SHORT SIDETONE PTT sidetones are used when PTT ID is activated. Sidetones are heard through the speaker when the operator first presses the PTT. They are used to tell the operator that he cannot yet speak until the ID has been transmitted. There are two sidetones available in the Radio. The PTT ID Sidetone is a continuous tone heard from PTT until the ID has been sent. The second tone, PTT Short Sidetone, is a short beep after the ID has been sent. Both tell the operator when he is permitted to speak into the microphone. One, both or no Sidetones maybe activated. This check box is set to enable the short sidetones. PREAMBLE BIT SYNC NUMBERPREAMBLE BIT SYNC NUMBER This parameter is programmable in the codeplug and defines the number of Preamble bit sync to transmit during pretime.

It was still maintained here for compatible with the old version of GM950 Plus. There are two different choices for this field : Call Alert and Call Alert/Voice. Call Alert leaves call indication at the receiving radio. Call Alert/Voice leaves a call indication and unmutes the loudspeaker of the receiving radio. AUTOMATIC MUTE TIMEAUTOMATIC MUTE TIME Data Operated Squelch(DOS) is used with to mute the data transmissions to reduce operator annoyance. DOS attempts to mute the speaker when data is present on the channel. Automatic mute keeps the speaker muted for a preset period of time from when carrier is detected by the squelch circuit. This allows the DOS time to detect any data activity, further reducing the annoyance of data being heard from the speaker. The range can be from 0 to 2040 ms in 8 ms steps. DOS COAST TIME DOS COAST TIME When MDC1200 signal is detected and then lost, the radio will not be unmuted for voice immediately. A delay will be executed first before the radio is unmuted. This delay is determined by the DOS Coast Timer. During this delay period, should MDC1200 signal be detected again then the radio will be muted and the DOS Coast Timer stopped and reset. This parameter indicates the duration of the DOS coast timer. The range is from 0 to 520 ms in 8 ms steps. There is one DOS Coast Time per Signalling. DOS BOTH CRITERIADDOS BOTH CRITERIA The basic DOS is a data mute feature comprising of the MDC1200 signal detector. Whenever, MDC1200 signal is detected, the radio speaker will be muted to prevent the MDC1200 signal to be heard by the user. When MDC1200 signal is no longer detected, the radio will be unmuted for voice transmission. The criteria for detecting the MDC1200 signal is determined by the option DOS Both Criteria which can take value either : (a) both 1800 Hz and 1200 Hz cycles (b) 1800 Hz or 1200 Hz cycles. There is one DOS Both Criteria per Signalling system. DOS MUTE ENABLEDOS MUTE ENABLE This field will enable/disable the DOS muted features. If this field is disabled, the radio won't muted speaker for any MDC1200 signal. CALL REMINDERCALL REMINDER Selecting this option will cause an X to be displayed in the box and the call reminder alert will be enabled. How long will the alert be repeated is programmable by the codeplug in MDC Radio Wide block. DECODE DISPLAYDECODE DISPLAY When a PTT ID transmission is received by the radio it contains the ID of the transmitting radio.

An example of this is a Police application, in which the various patrolmen may be 'Out of Service', 'Available', 'En Route', 'On Scene', etc. The purpose of the Status function in such a case is to help the dispatcher decide how to respond to new incidents by providing a quick, easy-to-use overview of the current disposition of the resources at his or her command. The current status of the radio can be changed by entering the status mode by pressing an programmable option button, "STATUS". Whenever the current status has been changed, the radio will automatically send the new status to a fixed end poll. The radio will also respond to the status query message from the base by sending the current status without any user intervention or notification. A maximun of 8 status entry may be programmed per radio. Valid status number is from 1 to 255. If enabled, the user may use the radio buttons to select a entry to indicate the current status. STATUS POWERUP MODESTATUS POWERUP MODE This field will determine how the radio set it's current status when the radio is powered-up. It can be 1. Designate Status 2. Last Status Designate status can be programmed through RSS. For Last Status, the radio will set it's current status upon powered-up to the last status before the radio is turning off. If the RAM checksum is wrong, then the radio will powerup with designate status. If designated status is not enabled or wrong, the radio will powerup with No Status. DESIGNATE STATUS_DESIGNATE STATUS Specified the current status of the radio when the radio is powered-up. STATUS ENABLESTATUS ENABLE Although maximum 8 status can be defined, each individual status can be disable by unchecked this check box. The status that are disabled will not be selected in the status mode. STATUS ALIASRSTATUS ALIAS For each Status entry, a status alias may be defined. This is what the display will show when the status entry is selected. When the status mode is enter, the display will show the alias or status number of the last status selected. The accepted characters used to define the status alias are 0-9,G,, A,b,C,d. STATUS ALIAS ENABLESTATUS ALIAS ENABLE This check box is used to determine how the radio will display the status. If this check box is checked, the status alias will be displayed; othrwise, the status number (1 - 8)itself will be display. STATUS FORMATSTATUS FORMAT This combo box will define the message format used in sending the status. It can be : 1. Status number (1 - 8). 2. Stauts message format. (1 - 255).

Once this call list is complete, you may use the 'Select' button to select the call type you wish to call. You also can use the up/down rocket buttons to scroll through the defined call entries. The list is built one entry at a time. The sequence of the entries is exactly the same as the order you would select them from the front of the radio. The entry sequence may be important for your customer, so it is best to check with him/her first. You may mix different signalling formats in any order in the list. Up to 128 different call entries are allowed. ID DISPLAY ALIASID DISPLAY ALIAS The name/number that will show on the radio display whenever this entry is being selected. We suggest that the number be large so that your customer can easily distinguish that this is not a channel number. CALL LIST REVERT CHANNELHCALL LIST REVERT CHANNEL This field determines on which channel the call will be sent. If you always want the call to go out on whatever channel your customer is on, then you can disable revert channel by set it to 0. Remember, however, that when the call is complete the radio will remain on the sending channel. SIGNALLING INDEXSIGNALLING INDEX This determines which MDC signalling format will be used when sending the call. This field can not be 0 since Select 5 signalling not applied in call mode. ACKNOWLEDGE EXPECTED5ACKNOWLEDGE EXPECTED This determines whether or not the radio will expect an acknowledge from unit(s) being called. If an acknowledge is expected, the radio will: a) send the call up to a number of times which can be defined as Retries Number in MDC Radio Wide block. b) display an 'A' if the call is acknowledged or a '-A' if not acknowledged. If an acknowledge is not expected, the radio will only send the call one time and will not show any type of acknowledge display. This field is only valid for individual call. So, it will be disable in group call and All Call. Additionally, the user also can use the wild character 'F' in Individual ID to define a group call. In this case, when the user confirm its setting, the RSS will automatic clear the Ack Expected field without any indication. CALL SERVICECALL SERVICE This field specified which type of call you are interested in. There are INDIVIDUAL, GROUP, or ALL call. 1) Individual ID - It is four digits long. The numbers 0-9 and letters A-F can be used. 'F' acts as a wildcard and 'E' is not available for the first digit. 2) Group ID - Three selectable digits, 0-F. 3) All CALL - This call is meant for all the radios in the system. SERVICE SERVICE This part of the RSS is used for the alignment of the radio. It contains 2 major windows, Tx Alignments and Rx Alignments and both these windows contain several screens which are required for the servicing and alignment of the receiver and transmitter. General The recommended hardware platform is a 386 or 486 DX 33 PC (personal computer) with 8 MByte RAM, MS DOS 3.3, Windows 3.xx, and RSS (Radio Service Software). These are required to align the radio. Refer to your RSS Installation Manual for installation and setup procedures for the required software; the user manual is accessed (and can be printed if required) via the RSS. To perform the alignment procedures, the radio must be connected to the PC, RIB (Radio Interface Box), and Universal Test Set as shown in figure 1. All tuning procedures are performed from the Service menu. Before going into the Service menu, the radio must first be read using the File / Read Radio menu (if the radio has just been programmed with data loaded from disk or from a newly created codeplug, then it must still be read so that the RSS will have the radios actual tuning values). All Service windows read and program the radio codeplug directly; you do NOT have to use the RSS Read Radio / Write Radio functions to program new tuning values. CAUTION: DO NOT switch radios in the middle of any Service procedure. Always use the Program or Cancel key to close the tuning window before disconnecting the radio. Improper exits from the Service window may leave the radio in an improperly configured state and result in seriously degraded radio or system performance. The Service windows introduce the concept of the 'Softpot', an analogue Software controlled Potentiometer used for adjusting all transceiver alignment controls. A softpot can be selected by clicking with the mouse at the value or the slider or by hitting the TAB key until the value or the slider is highlighted. Each Service window provides the capability to increase or decrease the softpot value with the mouse, the arrow keys or by entering a value with the keyboard. The window displays the minimum, maximum, and step value of the softpot. In addition transmitter tuning windows indicate the transmitter frequency and whether the radio is keyed. Adjusting the softpot value sends information to the radio to increase (or decrease) a DC voltage in the corresponding circuit. For example, increasing the value in the Reference Oscillator tune window instructs the radio microprocessor to increase the voltage across a varactor in the reference oscillator to increase the frequency. Clicking the Program button stores all the softpot values of the current window permanently in the radio. In ALL cases, the softpot value is just a relative number corresponding to a D/A (Digital- to-Analogue) generated voltage in the radio. All standard measurement procedures and test equipment are similar to previous radios. Refer to the RSS on-line help for information on the tuning software. Perform the following procedures in the sequence indicated. Note: All tuning procedures must be performed at a supply voltage of 13.2v unless otherwise stated. The Modulation Analyzer to measure the deviation should be set to frequency modulation with de-emphasis switched off and all high pass filters switched off. TX TUNINGTX TUNING The screens in this window are Bias Voltage, Battery Thresholds, RF Power, Reference Oscillator, Modulation Balance, Deviation Limit and Signalling Deviation.

Improper adjustment will result in poor operation and may damage the PA FET device. For this reason, the PA bias must be set before the transmitter is keyed the first time. Note that for certain radio models there are two bias voltage settings. For these radios both Bias 1 Voltage and Bias 2 Voltage need to be adjusted when aligning the PA Bias. For models that only have one bias voltage setting, the Bias 2 Voltage will be shown in grey on the service menu. 1. From the Service menu Tx Alignments 2. Select Bias Voltage to open the bias voltage tuning window. If the control voltage is out of range, an error message will be displayed. In this case the radio hardware has a problem and tuning must be stopped immediately. After entering the tuning window the bias is switched off and the quiescent current is 0 mA. The status bar will indicate wether the bias is switched on or off. 3. Measure the DC current of the radio. Note the measured value and add the specified quiescent current shown in table below.

The total of the two values (quiescent current and radio current with bias switched off) is the tuning target. BATTERY THRESHOLDBATTERY THRESHOLD The radio uses two battery threshold levels, Tx High and Tx Low, to determine the battery condition. Note: The Program buttons must only be activated when the power supply is set to the indicated voltage. If the RSS detects that the voltage is not within the expected range for the threshold in question then a message will be displayed to warn that the radio may not be set up correctly for the alignment operation. INADVERTANT USE OF THE PROGRAM BUTTONS MAY RESULT IN RADIO FAILURE. 1. From the Service menu, select Tx Alignments. 2. Select Battery Thresholds to open the battery thresholds tuning window. 3.

IMPORTANT: To set the transmitter power for customer applications use the Per Radio window under the Edit menu and set the Power 1 and Power 2 powers to the desired values. Only if the transmitter components have been changed or the transmitter does not transmit with the power set in the Per Radio window the following procedure should be performed. The advanced power setting technology employed in the radio makes use of two reference power level settings along with parameters describing the circuit behaviour. To determine these parameters the RSS requires the power values measured for two different settings. 1. From the Service menu, select Tx Alignments. 2. Select RF Power to open the RF power tuning window. The window will indicate the transmit test frequencies to be used. 3. Select the Point 1 value of the first frequency. 4. Click the Toggle PTT button to key the radio. The status bar will indicate that the radio is transmitting. 5. Measure the transmitter power on your power meter. 6. Enter the measured value in the box Point 1. 7. Select the Point 2 value of the first frequency. 8. Measure the transmitter power on your power meter. 9. Enter the measured value in the box Point 2. 10. Click the Toggle PTT button to dekey the radio. 11. Repeat steps 3 - 10 for all test frequencies shown in the window. 12. Click the Program button to store the softpot values. REFERENCE OSCILLATORREFERENCE OSCILLATOR Adjustment of the reference oscillator is critical for proper radio operation. Improper adjustment will not only result in poor operation, but also a misaligned radio that will interfere with other users operating on adjacent channels. For this reason, the reference oscillator should be checked every time the radio is serviced. The frequency counter used for this procedure must have a stability of 0.1 ppm (or better). 1. From the Service menu, select Tx Alignments. 2. Select Reference Oscillator to open the reference oscillator tuning window. The tuning window will indicate the target transmit frequency. 3. Click the Toggle PTT button to key the radio. The status bar will indicate that the radio is transmitting. 4. Measure the transmit frequency on your frequency counter. 5. Adjust the reference oscillator softpot in the tuning window to achiev a transmit frequency within the limits shown in table 2. 6. Click the Toggle PTT button again to dekey the radio and then click the Program button to store the softpot value. Table 2. Reference Oscillator Tuning RF-Band Target All Bands 150 Hz MODULATION BALANCE MODULATION BALANCE Compensation alignment balances the modulation sensitivity of the VCO and reference modulation (synthesizer low frequency port) lines. Compensation algorithm is critical to the operation of signalling schemes that have very low frequency components (e.g. DPL) and could result in distorted waveforms if improperly adjusted. The compensation value needs to be set at 7 frequencies across the frequency range. If the radio supports 20 or 25 kHz channel spacing selection, the procedure must only be performed for 25 kHz channel spacing. Values for 20 kHz channel spacing are calculated by the radio software. 1. From the Service menu, select Tx Alignments. 2. Select Modulation Balance to open the deviation balance tuning window. The window will indicate the transmit test frequencies to be used. 3. Set the Test Box (GTF180B) meter selector switch to the GEN position, and inject an 80Hz tone at 200 mVrms into the Audio In port. (The deviation measured at step 6 should be in the range of 1 - 4 kHz.) Connect an AC meter to the meter port to insure the proper input signal level. 4. Select the first test frequency shown in the window. 5. Click the Toggle PTT button to key the radio. The status bar will indicate that the radio is transmitting. 6. Measure the transmitter deviation. 7. Change the input tone to 3 kHz, 200 mVrms. 8. Adjust the deviation to within 2% of the value recorded in step 6. 9. Check the deviation at 80Hz again and repeat steps 7 - 8, if it has changed since step 6. 10. Click the Toggle PTT button to dekey the radio. 11. Repeat steps 3 - 10 for the remaining test frequencies. 12. Click the Program button to store the softpot values. Note: The step size change for step 8 is approximately 2.5% of the softpot value. DEVIATION LIMITDEVIATION LIMIT The transmit deviation limit softpot sets the maximum deviation of the carrier. The deviation value needs to be set at 7 frequencies across the frequency range. If the radio supports 20 or 25 kHz channel spacing selection, the procedure must only be performed for 25 kHz channel spacing. Values for 20 kHz channel spacing are calculated by the radio software.

The screens available in this window are Front End Filter, Squelch and Rated Volume. NOTE: All tuning procedures must be carried out at a supply voltage of 13.2v unless otherwise stated. FRONT END FILTER FRONT END FILTER Alignment of the front-end pre-selector is normally not required on these radios. Only if the radio has poor receiver sensitivity or the pre-selector parts have been replaced the following procedure should be performed. The softpot value sets the control voltage of the pre-selector. Its value needs to be set at 7 frequencies across the frequency range. If the radio supports 20 or 25 kHz channel spacing selection, use the parameters for 25 kHz channel spacing. 1.

Select Front End Filter to open the pre-selector tuning window. The window will indicat the receive test frequencies to be used. 4. Select the first test frequency shown, and set the corresponding value to the start value shown in table 6. 5. Set the RF test generator to the receive test frequency, and set the RF level to 10uV modulated with a 1 kHz tone at the normal test deviation shown in table 3. 6. Measure the RSSI voltage at accessory connector pin 15 with a dc voltmeter capable of 1 mV resolution and at least 1M ohm input impedance. 7. Change the softpot value by the stepsize shown in table 6 and note the RSSI voltage.The target softpot value is achieved when the measured RSSI voltage change between step 6 and step 7 is lower than the tuning target for the first time. The tuning target, shown in table 6, is expressed as the percentage of the measured RSSI voltage and must be recalculated for every tuning step. If the measured RSSI voltage decreases before the target value has been achieved, approximation should be stopped and the current softpot value should be used as target value. Set test box (GTF180B) audio switch to the 'SPKR' position. The 1 kHz tone must be audible at the target value to make sure the radio is receiving. 8. Repeat steps 4 - 7 for all test frequencies shown in the window. 9. Click the Program button to store the softpot values. Table 3.
