Troubleshooting And Repair; Table 11 Power-Up Self-Check Display - Motorola Spectra Service Manual

I. POWER-UP SELF-CHECK DISPLAYS (Spectra and Spectra 9000 Control Head)
When the radio is powered up, the control head goes through a self-test routine to check for system failures.
Table 11 lists the error messages that may appear in the display, followed by the possible causes and remedies.

TROUBLESHOOTING AND REPAIR

Table 11. Power–Up Self-Check Display
Spectra 9000
FAIL 01/81 The pattern stored in the memory board ROM is
incorrect.
FAIL 01/82 The pattern stored in the memory board EEPROM
is incorrect.
FAIL 01/83 Radio has conditions A and B.
FAIL 01/84 1. Memory board EEPROM is blank.
2. Microcomputer EEPROM is blank.
FAIL 01/85 Radio has conditions A and D.
FAIL 01/86 Radio has conditions B and D.
FAIL 01/87 Radio has conditions A, B and D.
FAIL 01/88 Memory board RAM defective.
FAIL 01/89 Radio has conditions A and H.
FAIL 01/8A Radio has conditions B and H.
FAIL 01/8B Radio has conditions A, B and H.
FAIL 01/8C Radio has conditions D and H.
FAIL 01/8D Radio has conditions A, D and H.
FAIL 01/90 Serial bus failure. May be a control head failure,
a radio command board failure, or a cabling failure.
FAIL 01/92 The pattern stored within the microcomputer
EEPROM is incorrect.
FAIL 01/93 Radio has conditions A and O.
FAIL 01/94 Microcomputer EEPROM is blank.
FAIL 01/95 Radio has conditions A and Q.
Control head ROM is defective.
Control head ROM is defective.
ERROR 01/02 Radio has an error with its EEPROM; one or more
modes in the radio have an incorrect pattern in the
memory board EEPROM. Radio will function nor-
mally until a corrupted mode is accessed; then,
"FAIL 002" will be displayed (see below).
Display malfunction.
FAIL 001 Synthesizer out-of-lock condition.
FAIL 002 The mode which has been accessed has an
incorrect pattern in the memory board EEPROM.
(Refer to ER 01/02 above, Item S).
FAIL 003 Mismatch between radio programming and
control head type.
FAIL 999 Serial number in the memory board and the
microcomputer do not match; Radio will
not function, but will allow test mode operation.
