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 a high-pitched self-test pass tone. If the self-test is not successful,
one low-pitched (300Hz) error tone is heard and the RED LED flashes several times to indicate the
reason for the failure (see Table 7-1 below). After flashing the error code, the LED remains off for 5
seconds and then repeats the error code. The LED sequence and the error tone continue until the
radio is switched off. Radios with displays are also able to display error codes. The meaning of the
LED indication, the displayed error codes and the related corrections are listed in Table 7-1.
