Section 4
POWER UP SELF-TEST
1.0 Power-Up Error Codes (Display Model only)
Upon powering up, the radio performs certain tests to determine if its basic electronics and software
are in working order. Any error detected has an associated error code that is presented on the radio
display. These error codes are intended to be used by a service technician when the radio
generates the Self Test Fail Tone. If these tests are successfully completed, the radio will generate
the Self Test Tone.
There are two classes of detectable errors, fatal and non-fatal. If it is considered as a fatal error, then
the normal radio operation will be inhibited. Fatal errors include hardware errors detected by the
microprocessor and certain memory errors. These memory errors include incorrect ROM checksum,
incorrect RAM checksum, and incorrect checksums of codeplug (Persistent Storage) blocks that
contain operating parameters. If the codeplug block operating parameters are corrupted, operation
of the unit on the proper frequency, system, and group are in question. Attempts to use this
information could provide the user with a false sense of security that others are receiving his
messages. Corrupted codeplug blocks of call IDs, or their associated aliases are considered non-
fatal errors. While the user may be inconvenienced, normal communication is still possible.

Error Code Description Error Type Corrective Action
ERROR 01/02 Call ID or associated
aliases codeplug block
checksum is wrong.
Non-Fatal Normal communication is still possible, but the
user may be inconvenienced.
Reprogram codeplug.
ERROR 01/22 Tuning Codeplug block

Non-Fatal Normal communication is still possible.
FAIL 01/82 External Codeplug block
checksum is wrong.
Fatal Reprogram codeplug.

sum error
Fatal Reprogram codeplug.

Fatal Reprogram codeplug.
FAIL 01/81 ROM Checksum is
wrong.
Fatal Reprogram FLASH Memory, then retest. If
message reoccurs, replace main board or
send radio to nearest Motorola Depot.
FAIL 01/88 Radio RAM Test Failure. Fatal Retest radio by turning it off and turning it on
again. If message reoccurs, replace main
board or send radio to nearest Motorola
Depot.
FAIL 01/90
or
FAIL 02/90

failure.
Fatal Retest radio by turning it off and turning it on
again. If message reoccurs, replace main
board or send radio to nearest Motorola
Depot.
