key and 7. 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 pick-up has been used, and by comparing it with the total recording time at the time when an error occurred in the selfdiagnosis result display mode, you can determine when the error occurred. Clear the total recording time, if the optical pick-up was replaced. 7-1. Operation of The Self-Diagnosis Result Display Mode 1. Enter the test mode (Display Check mode). 2.
