SECTION 1
Important Safety Precautions
1.1 Safety Precautions
!Burrs formed during molding may be left over on some parts of the chassis. Therefore,
pay attention to such burrs in the case of preforming repair of this system.
!Please use enough caution not to see the beam directly or touch it in case of an
adjustment or operation check.
!This unit can only be connected to the JVC car receivers/controllers equipped with
MP3-CD changer control functions. If connected to any other receiver/controller, this
unit cannot work (even CDs may not play back).

1.2 Preventing static electricity
Electrostatic discharge (ESD), which occurs when static electricity stored in the body, fabric, etc. is discharged,
can destroy the laser diode in the traverse unit (optical pickup). Take care to prevent this when performing repairs.
1.2.1 Grounding to prevent damage by static electricity
Static electricity in the work area can destroy the optical pickup (laser diode) in devices such as DVD players.
Be careful to use proper grounding in the area where repairs are being performed.
(1) Ground the workbench
Ground the workbench by laying conductive material (such as a conductive sheet) or an iron plate over it before placing the
traverse unit (optical pickup) on it.
(2) Ground yourself
Use an anti-static wrist strap to release any static electricity built up in your body.
(3) Handling the optical pickup
• In order to maintain quality during transport and before installation, both sides of the laser diode on the replacement optical
pickup are shorted. After replacement, return the shorted parts to their original condition.
(Refer to the text.)
• Do not use a tester to check the condition of the laser diode in the optical pickup. The tester's internal power source can
easily destroy the laser diode.
1.3 Handling the traverse unit (optical pickup)
(1) Do not subject the traverse unit (optical pickup) to strong shocks, as it is a sensitive, complex unit.
(2) Cut off the shorted part of the flexible cable using nippers, etc. after replacing the optical pickup. For specific details, refer to
the replacement procedure in the text. Remove the anti-static pin when replacing the traverse unit. Be careful not to take too
long a time when attaching it to the connector.
(3) Handle the flexible cable carefully as it may break when subjected to strong force.
(4) I t is not possible to adjust the semi-fixed resistor that adjusts the laser power. Do not turn it.
1.4 Attention when traverse unit is decomposed
*Please refer to "Disassembly method" in the text for the CD pickup unit.
• Apply solder to the short land before the flexible wire is disconnected from the connector on the CD pickup unit.
(If the flexible wire is disconnected without applying solder, the CDpickup may be destroyed by static electricity.)
• In the assembly, be sure to remove solder from the short land after connecting the flexible wire.

tion.
(3) When applying grease, refer to the Exploded View. Use
new grease.
2.2 Mechanism Section
(1) Remove the exterior (required section only).
(2) The mechanism section is designed so that each unit can
be removed separately.
(3) When reassembling, refer to 2-5.Precautions reassem-
bling. (Use new grease when applying grease.)
2.3 Exterior Section
2.3.1 Removing the bottom cover and front panel assem-
bly (See fig.1~4)
(1) Remove the screw Ato unlock the mounting direction
knob located on the side of the main unit.
(2) Turn the mounting direction knob in the direction of the ar-
row using a coin, etc. to remove it. (The knob can be re-
moved only when it is set to this position.)
(3) Remove the four screws Battaching the bottom cover on
both sides of the main unit.
(4) Turn the unit upside down so the bottom surface is facing
upward.
(5) Lift the rear edge of the bottom cover slightly and lift the
side by grasping the DIN jack section on the side panel,
then turn it toward the front (raise upward) to remove the
bottom cover.
(6) Release the four joints on both sides of the front panel,

2.5 Precautions reassembling
REFERENCE:
When reassembling, also refer to the disassembling proce-
dures.
2.5.1 Mounting the traverse mechanism assembly (See
fig.30~34)
(1) When mounting the pickup assembly, attach the feed slide
shaft assembly to the traverse chassis. Apply E-JC-525
grease to the shaft.
(2) Mount the middle gear and the feed slide shaft to the
traverse chassis and secure them with the screw O
through the shaft holder.
(3) Before attaching the mechanism board, move the pickup
to the outer edge position, then attach the mechanism
board using the screw M. At this time, check that the rest
switch is correctly placed.
(4) To mount the rack arm, first move the pickup to the middle
position and fixing it with the screw P.
CAUTION:
When reassembling the mechanism board, reattach the
flexible wire to connector CN603 on the mechanism
board, and then unsolder the sorting round point. Next,
reattach the mechanism board with screw M.

2.5.2 Mounting the lifter unit (See fig.35~37)
(1) Insert the shafts eof the traverse mechanism assembly
into the slide grooves fon the lifter unit.
(2) Move the hook of the lifter unit to the edge, and move the
sliding lever inside the side bracket unit to the edge as
well.
(3) With each hole and lever shifted to the edge, mount the lift-
er unit and side bracket unit from the side. (Check each at-
tached section, and check that the joint g of the lifter unit
is correctly inserted into the holes hof the side bracket
unit. After reassembled, check that levers move together.)
(4) Turn the lifter unit upside down.
As shown in Fig. 37, slide the lever 30 mm away from the
edge, and then mount the lifter bracket (L) assembly.
