Section 5
POWER UP SELF-TEST
Turning on the radio using the on/off volume control starts a self-test routine which checks the RAM,
EEPROM hardware and EEPROM checksum. Pressing and holding SB1 while turning on the radio
causes the self-test routine to check for the ROM checksum as well. If these checks are successfully
completed, the radio will generate the Self-Test Pass Tone. If the self-test is not successful, a Self-
Test Fail Tone is heard.
