8.9 Power Up Self-Test 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. The displayed error codes and related corrections
are as follows:
