POWER UP SELF-TEST
1.0 Error Codes
Turning on the radio starts a self-test routine that checks the radio functionality. If the checks are
successful, the radio generates two high-pitched self-test pass tones, or a musical tone (selected in
CPS). If the self-test is not successful, one low-pitched tone is heard. Radios with displays are able
to display the error codes. The displayed error codes and related corrections are listed in Table 7-1.
Ta b l e 7 - 1PowerUpErrorCodes
If the error code
displayed is...then, there is a... To correct the problem...
“Chan Spacing”Invalid channel spacing.Reprogram codeplug with correct spacings.
“EEPROM Cksum”Codeplug structure mismatch or
non-existence of codeplug.Reprogram codeplug with correct version
and retest radio.
If message reoccurs, replace main board or
return it to the nearest Motorola depot.
“Synth Lock”Channel frequency invalid for radio
model.Reprogram codeplug with correct
frequency and channel range.
“RF Config”Channel frequency outside allowed
range or invalid channel number for
channel frequency plan.Reprogram codeplug with valid
frequencies/channels.
“RAM Test”RAM test failureTurn radio off-on.
If message reoccurs replace main board or
return it to the nearest Motorola depot.
“Personality D”Personality data invalid Reprogram codeplug with valid personality.
“Dynamic CP”Dynamic codeplug failure.Turn radio off then on.
If message reoccurs replace main board or
return it to the nearest Motorola depot.
“Flash Cksum”Radio EPROM failure. Turn radio off then on.
If message reoccurs replace main board or
return it to the nearest Motorola depot.
“Hardware Test”Radio hardware failure.Turn radio off-on.
If message reoccurs replace main board or
return it to the nearest Motorola depot.
No Display Display module is not connected.
Display module faulty.Check connection between main board and
the display module.
Replace display module.
300Hz Tone
(Radio Without Display)Radio hardware failure or invalid
codeplug.Turn radio off then on.
If tone still sounds reprogram codeplug and
retest. If tone continues to sound replace
the main board or return it to the nearest
Motorola depot.
