6.3 ADJUSTMENT OF ELEVATION WHEN THE CD CORE UNIT HAS BEEN REMOVED
FOR MAINTENANCE
A
- Adjustment When Error Code 60 is Displayed Because of Malfunctioning Elevation
•Note :
Unlike the conventional mechanisms, the new mechanism detects the height of the stage using slide-variable
resistance.
To absorb dislocation of the stage height caused by differences in the mechanism and the CD core unit, adjust-
ment must be made for each CD-mechanism module using a variable resistor.
Normally, readjustment is not needed, as this has been adjusted at the factory. However, adjustment of elevation
is required according to the procedure explained below if an elevation error has occurred or if the CD core unit
has been removed.
•Purpose :
B
To adjust and confirm whether or not elevation operates correctly.
•Adjustment Method :
•Measuring Equlpment: Millivoltmeter
•Measuring Points :
•Setting : Without a magazine in Test mode
