#### Recommended action

If an occasional warning of this type is received, but the system otherwise shows no symptoms of faults, that can be related to the EEPROM, such warnings can be ignored. If several warnings of this type are obtained or the system shows fault symptoms that probably are related to the EEPROM, the CPU board should be replaced. As an alternative, the identified EEPROM circuit can be replaced. The system must be reprogrammed, preferable from a backup.
