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 pick-up has been used, and by comparing it with the total
recording time at the time when an error occurred in the self-diag-
nosis result display mode, you can determine when the error oc-
curred.
Clear both self-diagnosis history data and total recording time, if
the optical pick-up was replaced.
