SUMMARY
Flash memory on the CPU BOARD is damaged.
SEQUENCE OF EVENTS
The Flash EPROM is check--summed when the IMAGER is energized. The error message is generated if
the checksum is incorrect.
PHONE FIX - - OPERATOR CORRECTABLE
De-energize the IMAGER. Wait 5 seconds, then energize the IMAGER.
ON SITE - -TECHNICIAN CORRECTABLE
Problem -- The IMAGER firmware has failed.
Solution -- Reload the firmware at 19.2 K BTS. If this does not correct the problem, install a new CPU
BOARD.
TECH TIPS
THEORY
During self-test and after new firmware has been uploaded, the IMAGER does a checksum on the Flash
EPROM. If the checksum is not successful, the IMAGER automatically sets the SERVICE PORT to a baud
rate of 19.2 K, with 8 bits, no parity, and one stop bit, so that the firmware is uploaded at this slower speed.
