4-8. 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.
