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.
If the error code
displayed is...
"Chan Spacing"
"EEPROM Cksum"
"Synth Lock"
"RF Config"
"RAM Test"
"Personality D"
"Dynamic CP"
"Flash Cksum"
"Hardware Test"
