DISASSEMBLY FOR REPAIR
REMOVE CD MECHANISM
After remove insulator ass'y, then remove some LR side board.
Next remove the top and the bottom boards.
1) Remove the 6 screws1, then remove the front panel.
2) Remove the 6 screws23, then remove the CD mechanism.
When assemble the front panel, insert the phone jack with tak-
ing care4.
ELECTRIC CHECK
After assemble the sub panel and the front panel.
1) Remove the 8 screws 5, 6, then remove PCB(X09:B/4), PCB(X14:A/6).
2) Remove the 2 screws 7, the 3 PC supports8, then remove the CD mechanism.
3) After assemble PCB (X09:B/4) on the main PCB with the rear panel. then connect GND between the rear panel , the anten-
na and the CD mechanism with 3 alligator clip wires(0).
★Remove the MULTI CONTROL knob with a string(wires etc)-.

1. 8cm DISC loading in
1) Insert a disc îCheck by a disc detection sensor2(prism
reflection ray OFF) îStart loading motor3îMove the
roller4îPull in a disc
2) Push the shaft of the arm assy (trigger A )5with a disc î
Move the arm assy(trigger B)6îMove the arm

The DC voltage is an actual reading measured
with a high impedance type voltmeter. The mea-
surement value may vary depending on the
measuring instruments used or on the product.
Refer to the voltage during PLAY unless other-
wise specified; The value shown in ( ) is the
voltage measured at the moment of STOP.
