When entered in the TEST MODE, this set provides the Overall  
Adjustment mode which allows CD and MO discs to be auto-  
matically adjusted. In the OverallAdjustment mode, the system  
discriminates between CD and MO discs, performs adjustments  
in sequence automatically, and displays the faulty location if  
any fault is found. In the Manual mode, selected adjustments  
can be performed automatically.

This mode is designed to adjust the servo system automatically by  
going through all the adjustment items.  
Usually, this mode is used to perform automatic adjustments when  
servicing the set.

4-6. SELF-DIAGNOSTIC DISPLAY MODE  
4-6-1. Outline of the function  
The Self-diagnostic system is used in this set. If an error occurs  
during playback, this system detects the fault through the  
microprocessor’s mechanism and power control blocks and stores  
the cause in EEPROM in a history format.  
This history, which can be viewed in the TEST MODE, provides  
the means of locating the fault in troubleshooting.
