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

microcomputer detect it and record its cause as history in the

nonvolatile 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.
