RESET SWITCH
This CD /TUNER and TAPE DECK/ PRE-AMPLIFIER unit is provided with areset switch on the rear panel. The reset switch
serves to initialize the microprocessor in the each units which controls the CD, TUNER, TAPE DECK and etc block. If the unit
is to be serviced or key input is not acknowledged even when the CD /TUNER, TAPE DECK and etc. operation buttons are
pressed, press the RESET switch and initialize the microprocessor following the step below.
1. Disconnect the AC power cord from the power outlet.
2. Keep the RESET switch depressed for 60 seconds.
(The backed up electrolytic capacitor is discharged by keeping the RESET switch depress.)
3. Reconnect the AC power cord to the power outlet.
4. Press the CD /TUNER, TAPE DECK and etc. operations, and check their operation.

REMOVAL AND INSTALLATION
●Disconnect the power cord’s plug from the electrical outlet.
.All wiring should be returned to the original position after work is completed.
●First have ready many the new FIXERS (614 129 2496) for replacement.
.Arrange the lead wires so that they are not near the heat sink.

DISASSEMBLE OF THE CD MECHANISM
1. Preparations
1)Do not apply unnecessary force to the pickup when handing it. Care should be taken not even to touch the lens of dr e
d
circuit sections.
2) Do not apply unnecessary force (do not pull or push it forcefully) to remove the disc tray from its inside position.
Unnecessary force may break the teeth on the tray gear (CM6).
3) In the descriptions which follow, the numbers in the parentheses after the parts are reference numbers in the exploded
views. Refer to these views.
2. Removing and installing the disc tray
1)Remove the stop screw (YI )of the disc tray (31). (0)
2) Pull the disc tray (31) all the way forward by turning the tray DISC
drive gear (CM12) clockwise. (@)
Note :Do not take hold ‘of the disc tray (31) and pull it out
by force.
3) Push the catch on the disc tray (31) in the direction shown
by the arrow, and draw out the disc tray (31). (@)
4) To install the disc tray, turn the gear (CM12)-in the direction
of the arrow as far as it will go. (@)
5) Align the disc tray (31) with the mechanism chassis (CM39).
Adjusting second tooth of the tray move gear (CM3). (C9)
6) Push the disc tray (31) toward the rear, and interlock it with /
TRAY REPLACEMENT
SECOND TOOTH OF TRAY MOVE GEAR
the tray drive gear (CM12) as shown in Fig. Q.
7) Secure it with the screw (Yl )which was removed in step 1).
3. Disassembling the mechanism
(1) Removing the pickup block
1) Remove the disc tray (31). (Refer to steps 1), 2) and 3) of )
the section entitled “Removing and installing the ,disc t(ay”)”
2) Turn the tray drive gear (CM12) counterclockwise’””(0), and
move the pickup in the direction of arrow (@) as far as it will
go. R
3) Remove the spring wire (CM44) with tweezers. (@)
4) Remove the screw (CM11 ), and also remove the tray drive
gear (CM12) and washer (CM13). (0)
5) Now remove the pick rack gears (CM16 and CM19).
Note :It will not be possible to remove the pick rack gears
(CM16 and CM19) unless the pickup has been
moved all the way in the direction of arrow (@).
6) The pickup block can now be removed by taking out the
screw (CM51 )and spring coil (CM49).
Note :If the timing gear (CM23) is in the state shown by “X”
in the figure on the right, put it in the state shown by
“o”.
