POWER UP SELF-TEST

1.0 Error Codes

Turning on the radio starts a self-test routine that checks the RAM, ROM checksum, EEPROM

hardware, and EEPROM checksum. If these checks are successful, the radio generates two high-

pitched self-test pass tones. If the self-test is not successful, one low-pitched tone is heard. Radios

with displays are able to display the error codes. Following are the possible errors and the related

connections.

Table 5-1 Power Up Error Codes

Possible Errors To correct the problem...

RAM test failure. Retest the radio by turning it off and turning it on

again. If bad tone reoccurs, replace RAM (U0122).

Codeplug structure mis-

match or non existence of

codeplug.

Reprogram codeplug with correct version and retest

radio. If message reoccurs, replace EEPROM

(U0111).

Wrong codeplug checksum. Reprogram codeplug.
