Normally, automatic adjustment is executed in this mode at the repair.

SELF-DIAGNOSIS RESULT DISPLAY MODE

This set uses the self-diagnostic function system in which if an error occurred during the recording or playing, the mechanism control block and the power supply control block in the micro- computer detect it and record its cause as history in the nonvola- tile memory.

By checking this history in the test mode, you can analyze a fault and determine its location.

Total recording time is recorded as a guideline of how long the optical pickup has been used, and by comparing it with the total recording time at the time when an error occurred in the self- diagnosis result display mode, you can determine when the error occurred.

Clear both self-diagnosis history data and total recording time, if the optical pickup was replaced.
