Safety Precautions

1. This design of this product contains special hardware and many circuits and components
specially or safety purposes. For continued protection, no changes should be made to the
original design unless authorized in writing by the manufacturer. Replacement parts must be
identical to those used in the original circuits. Services should be performed by qualified
personnel only.

2. Alterations of the design or circuitry of the product should not be made. Any design
alterations of the product should not be made. Any design alterations or additions will void
the manufacturer`s warranty and will further relieve the manufacture of responsibility for personal
injury or property damage resulting therefrom.

3. Many electrical and mechanical parts in the products have special safety-related characteristics.
These characteristics are often not evident from visual inspection nor can the protection
afforded by them necessarily be obtained by using replacement components rated for higher
voltage, wattage, etc. Replacement parts which have these special safety characteristics are
identified in the Parts List of Service Manual. Electrical components having such features are
identified by shading on the schematics and by ( ) on the Parts List in the Service Manual.
The use of a substitute replacement which does not have the same safety characteristics as
the recommended replacement parts shown in the Parts List of Service Manual may create
shock, fire, or other hazards.

4. The leads in the products are routed and dressed with ties, clamps, tubings, barriers and the
like to be separated from live parts, high temperature parts, moving parts and/or sharp edges
for the prevention of electric shock and fire hazard. When service is required, the original lead
routing and dress should be observed, and it should be confirmed that they have been
returned to normal, after re-assembling.

5. Leakage currnet check (Electrical shock hazard testing)

After re-assembling the product, always perform an isolation check on the exposed metal

parts of the product (antenna terminals, knobs, metal cabinet, screw heads, headphone jack,
control shafts, etc.) to be sure the product is safe to operate without danger of electrical
shock. Do not use a line isolation transformer during this check.

  Plug the AC line cord directly into the AC outlet. Using a "Leakage Current Tester",

measure the leakage current from each exposed metal parts of the cabinet , particularly any
exposed metal part having a return path to the chassis, to a known good earth ground. Any
leakage current must not exceed 0.5mA AC (r.m.s.)

  Alternate check method

Plug the AC line cord directly into the AC

outlet. Use an AC voltmeter having, 1,000
ohms per volt or more sensitivity in the follow­ing manner. Connect a 1,500

!

Warning

1. This equipment has been designed and manufactured to meet international safety standards.

2. It is the legal responsibility of the repairer to ensure that these safety standards are maintained.

3. Repairs must be made in accordance with the relevant safety standards.

4. It is essential that safety critical components are replaced by approved parts.

5. If mains voltage selector is provided, check setting for local voltage.

In regard with component parts appearing on the silk-screen printed side (parts side) of the PWB diagrams, the
parts that are printed over with black such as the resistor ( ), diode ( ) and ICP ( ) or identified by the “ ” mark
nearby are critical for safety.
When replacing them, be sure to use the parts of the same type and rating as specified by the manufacturer.
(Except the J and C version)

! CAUTION

Burrs formed during molding may
be left over on some parts of the
chassis. Theref ore, pay attention to
such burrs in the ca se of pref orm­ing repair of this system.

WARNING LABEL

Preventing static electricity

1. Grounding to prevent damage by 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.

2. About the earth processing for the destruction prevention by static electricity

In the equipment which uses optical pick-up (laser diode), optical pick-up is destroyed by the static
electricity of the work environment.
Be careful to use proper grounding in the area where repairs are being performed.

2-1 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.

2-2 Ground yourself

Use an anti-static wrist strap to release any static electricity built up in your body.

3. Handling the optical pickup

1. 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.)

2. 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.

4. Handling the CD changer unit (optical pickup)

1. Do not subject the CD changer 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 CD changer 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. It is not possible to adjust the semi-fixed resistor that ad­justs the laser power. Do not turn it.

Attention when traverse unit is decomposed

*Please refer to "Disa ssembly method" in the text f or pick

up and how to detach the CD changer mechanism.

1. Remove the CD changer unit.

2. Disconnect the harness from connector on the CD motor
board.

3. Solder is put up before the card wire is removed from connector
Cn601on the main board as shown in Fig.1 and Fig. 2.

(When the wire is removed without putting up solder, the CD

pick-up assembly might destroy.)

4. Please remove solder after connecting the card wire with
CN601 when you install picking up in the substrate.

Maintenance of laser pickup

(1) Cleaning the pick up lens

Before you replace the pick up, please try
to clean the lens with a alcohol soaked cot­ton swab.

(2) Life of the laser diode

When the life of the laser diode has expired,
the following symptoms will appear.

1. The level of RF output (EFM output: ampli
tude of eye pattern) will below.

Replacement of laser pickup

(3) Semi-fixed resistor on the APC PC board

The semi-fixed resistor on the APC printed circuit board which is attached to the pickup is used to adjust the
laser power. Since this adjustment should be performed to match the characteristics of the whole optical block,
do not touch the semi-fixed resistor.
If the laser power is lower than the specified value, the laser diode is almost worn out, and the laser pickup should
be replaced.
If the semi-fixed resistor would be adjusted when the pickup operates normally, the laser pickup may be dam­aged due to excessive current.
