If the diagnosis result is OK, the system enters the test mode.If the diagnosis result is NG, the oscillation of the sub clock is diagnosed again. If the result is OK, the systementers the test mode. If the diagnosis result is continuously NG 5 times, the system stops with “ERR1“and“ERR2“displayed.Test ModeKeysSetting MethodCD MODECD PLAY keyDECK MODETAPE PLAYInsert the AC cord to AC wall* SUB CLOCK OSC DIAGNOSISMODE keyoutlet while holding down the left key.4.
