Installation:
---------------
1) When you insert the Installation CD into the CD-ROM drive, the 
   installation will start automatically if you have auto start enabled for
   your PC. Follow the on-screen instructions to install the software.
2) Please refer to the CPS Programming Installation Guide, which you
   received with this software for more detailed information. It is very
   important that the steps in both the "Installation of the CPS and Tuner"
   and the "Optimizing the Communication Setup" section of the Guide be
   followed carefully.  Failure to follow any of these steps may result in
   being unable to communicate with your radios.
3) Before uninstalling the Tuner, close the CPS Launcher if it is running
   in the system tray.

Connecting the PC to the radio:
-------------------------------
Do not use the Radio Interface Box (RIB), Smart Radio Interface
Box (SRIB) or any of the cables that plug into those boxes.
Use only the following direct PC to radio cables:
 XTS 2500 / XTS 5000 RS232 cable = RKN4106
 XTS 2500 / XTS 5000 USB cable = RKN4105
   NOTE: When using the USB cable, be sure to always click "Yes" on the
   Digital Signature window whenever it is displayed by your operating
   system. Note that the USB cable can be used only with the Windows ME and
   Windows 2000 (SP 2 or higher) operating systems.
 ASTRO Spectra Plus RS232 cable = HKN6155

Known issues:
-------------
1) In the event that PC to radio communications fail even after 
   attempting to read the radio a few times, it might be necessary 
   to reset the communications by either turning the radio off/on or 
   by disconnecting/reconnecting the cable connected to the radio.
2) Only one RS232 COM port can be configured for Tuner use and
   that port must be specified at the time of installation. 
3) PC to radio communications will sometimes fail if you attempt
   to read the radio immediately after closing the previous tuning
   session. Wait for the "hourglass" to disappear before reading
   the radio again.
4) In the event that PC to radio communications fail even after
   restarting both the Tuner and the radio it may be necessary to
   "Hang-up" the stalled connection. Do this by going to
   My Computer -> Dial Up Networking and clicking "Hang-up" or
   "Disconnect" if visible on any of the connections named
   "ConnMot..."
5) When using a VHF radio, frequencies lower than 136.02500 MHz are not
   supported by either the "Transmitter Test Pattern" or "Bit Error Rate"
   screens.
