m@ Error Code Display and Servo Adjustment Function
This unit has an error code display function, so that if the unit operates incorrectly, the fault is displayed using an error
code on the FL display of the Tuner/Amplifier (SA-EH60). It also has a servo adjustment function for displaying the
status of servo system functions (Focus, Tracking, CLV Servo) on the FL display of the Tuner/Amplifier.
The system control IC and FL display are part of the Tuner/Amplifier so make sure the system has been connected
properly before using three functions. (This unit can be operated independently, although the error code display and
servo adjustment functions cannot be used.)
Use these two functions for guidance during fault diagnosis and repair.
Note:
Check beforehand for scratching or soiling of the test disc (SZZP1054C), and soiling or other problems with
the pickup lens.
