To engineers in charge of repair or

inspection of our products.

that the laser optical diode lights up, keep your eyes

more than 30cms away from the lens. Prolonged

viewing of the laser within 30cms may damage your

eyesight.

9. Cautions in handling the optical pickup

The laser diode of the optical pickup can be damaged

by electrostatic charge caused by your clothes and body.

Make sure to avoid electrostatic charges on your clothes

or body, or discharge static electricity before handling

the optical pickup.

9-1.Laser diode

The laser diode terminals are shorted for transportation

in order to prevent electrostatic damage. After

replacement, open the shorted circuit. When removing

the pickup from the mechanism, short the terminals by

soldering them to prevent this damage.

9-2.Actuator

The actuator has a powerful magnetic circuit. If a

magnetic material is put close to it. Its characteristics

will change. Ensure that no foreign substances enter

through the ventilation slots in the cover.

9-3.Cleaning the lens

Dust on the optical lens affects performance. To clean

the lens, apply a small amount of isopropyl alcohol to

lens paper and wipe the lens gently.

Before repair or inspection,make sure to follow the

instructions so that customers and Engineers in charge of

repair or inspection can avoid suffering any risk or injury.

Use specified parts.

The system uses parts with special safety features

against fire and voltage. Use only parts with equivalent

characteristics when replacing them.

The use of unspecified parts shall be regarded as re-

modeling for which we shall not be liable.The onus of

product liability (PL) shall not be our responsibility in

cases where an accident or failure is as a result of

unspecified parts being used.

Place the parts and wiring back in their original

positions after replacement or re-wiring.

For proper circuit construction, use of insulation tubes,

bonding, gaps to PWB, etc, is involved. The wiring con-

nection and routing to the PWB are specially planned

using clamps to keep away from heated and high volt-

age parts. Ensure that they are placed back in their

original positions after repair or inspection.

If extended damage is caused due to negligence dur-

ing repair, the legal responsibility shall be with the re-

pairing company.

CAUTIONS

Check for safety after repair.

Check that the screws, parts and wires are put back

securely in their original position after repair. Ensure

for safety reasons there is no possibility of secondary

problems around the repaired spots.

If extended damage is caused due to negligence of re-

pair, the legal responsibility shall be with the repairing

company.

The appliance contains a laser system and is classified as

a “CLASS 1 LASER PRODUCT” . In case of any trouble

with this player, please contact your nearest “authorized

service station”. To prevent direct exposure to the laser

beam, do not try to open the enclosure.

Caution in removal and making wiring connection to

the parts for the automobile.

Disconnect the battery terminal after turning the igni-

tion key off. If wrong wiring connections are made with

the battery connected, a short circuit and/or fire may

occur. If extensive damage is caused due to negligence

of repair, the legal responsibility shall be with the repair-

ing company.

Cautions regarding chips.

Do not reuse removed chips even when no abnormal-

ity is observed in their appearance. Always replace them

with new ones. (The chip parts include resistors, ca-

pacitors, diodes, transistors, etc). The negative pole of

tantalum capacitors is highly susceptible to heat, so

use special care when replacing them and check the

operation afterwards.

Cautions in handling flexible PWB.

Before working with a soldering iron, make sure that the

iron tip temperature is around 270-C. Take care not to

apply the iron tip repeatedly (more than three times) to the

same patterns. Also take care not to apply the tip with

force.

Turn the unit OFF during disassembly and parts replace-

ment. Recheck all work before you apply power to the

unit.

TROUBLESHOOTING

Problem

Cause

Measure

Power does not turn on.

(No sound is produced).

Fuse is blown.

Replace with a fuse of the same amperage. If the

fuse blows again, consult your store of purchase.

Incorrect wiring

Consul your store of purchase.

Compact disc cannot be

loaded.

Another compact disc is already

loaded.

Eject the compact disc before loading the new

one.

Compact disc is dirty.

Clean the compact disc with a soft cloth.

Sound skips or is noisy.

Compact disc is heavily scratched

or warped.

Replace with a compact disc with no scratches.

Sound is bad directly after

power is turned on.

Water droplets may form on the

internal lens when the car is

parked in a humid place.

Let dry for about 1 hour with the power on.

Nothing happens when button

are pressed.

Display is not accurate.

Microprocessor has

malfunctioned due to noise, etc.

Turn off the power, then press the [RELEASE]

[RELEASE]

button and remove the DCP.

Press the reset button for about 2 seconds with a

thin rod.

DCP or main unit connectors are

dirty.

Wipe the dirt off with a soft cloth moistened with

cleaning alcohol.

ADJUSTMENT

Procedure

Measuring Instrument

S-Meter

1. Input the 98.1MHz/30dB u

(400Hz-MOD 30%) signal.

2. Turn on the power switch.

And press the AF button

and CH6 button at the

same time. (TEST MODE)

3. Adjust the reading of LCD

indicator to [24----00]

(2.4 ± 0.2V) by VR101.

ERROR DISPLAYS

To protect the system, this unit has been equipped with self diagnostic functions. If a fault arises, a warning is

issued by various error displays. Follow the corrective measures and remove the fault.

Corrective Measure

Error Display

This error display indicates that a fault has arisen in the mechanism of the

source unit (for example, the disc cannot be ejected).

-Check the source unit

ER2

This error display indicates that the pickup focus is off because of a scratched

disc or some other factor during source unit play.

-Check the compact unit

ER3

This indicates that the CD’s TOC (table of contents) cannot be read, because

the selected disc is upside-down.
