CDX-M1026ZG
•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 :
To adjust and confirm whether or not elevation operates correctly.
•Adjustment Method :
•Measuring Equipment: Millivoltmeter
•Measuring Points :
EREF, EPVO
•Setting : Without a magazine in Test mode
With the mechanism placed upside-down (Place the CD mechanism module so that the
CD core unit is above.)
•Confirmation Procedure
1. Press key 10 enter Test mode, then select Multi-CD player.
2. Press key 3 to enter Mechanism Test mode.
3. Press key 8 twice to specify the amount of movement.
