6. 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-EH760). 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
these functions. 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.
