To engineers in charge of repair or

inspection of our products.

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.

1. 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 remodeling

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.

2. Place the parts and wiring back in their original positions after

replacement or re-wiring.

For proper circuit construction, use of insulation tubes, bond-

ing, gaps to PWB, etc, is involved. The wiring connection and

routing to the PWB are specially planned using clamps to keep

away from heated and high voltage parts. Ensure that they are

placed back in their original positions after repair or inspec-

tion.

If extended damage is caused due to negligence during re-

pair, the legal responsibility shall be with the repairing com-

pany.

3. 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 ploblems around the re-

paired spots.

If extended damage is caused due to negligence of repair, the

legal responsibility shall be with the repairing company.

4. Caution in removal and making wiring connection to the parts

for the automobile.

Disconnect the battery terminal after turning the ignition key

off. If wrong wiring connections are made with the battery con-

nected, a short circuit and/or fire may occur. If extensive dam-

age is caused due to negligence of repair, the legal responsi-

bility shall be with the repairing company.

5. Cautions in soldering

Please do not spread liquid flux in soldering.

Please do not wash the soldering point after soldering.

6. Cautions in soldering for chip capacitors

Please solder the chip capacitors after pre-heating for replace-

ment because they are very weak to heat.

Please do not heat the chip capacitors with a soldering iron

directly.

7. Cautions in handling for chip parts.

Do not reuse removed chips even when no abnormality is ob-

served in their appearance. Always replace them with new

ones. (The chip parts include resistors, capacitors, diodes, tran-

sistors, etc).

Please make an operation test after replacement.

8. Cautions in handling flexible PWB

Before working with a soldering iron, make sure that the iron

tip temperature is around 270

iron tip repeatedly(more than three times)to the same patterns.

Also take care not to apply the tip with force.

9. Turn the unit OFF during disassembly and parts replacement.

Recheck all work before you apply power to the unit.

. Take care not to apply the

10. Cautions in checking that the optical pickup lights up.

The laser is focused on the disc reflection surface through the

lens of the optical pickup. When checking that the laser opti-

cal diode lights up, keep your eyes more than 30cms away

from the lens. Prolonged viewing of the laser within 30cms

may damage your eyesight.

11. Cautions in handling the optical pickup

The laser diode of the optical pickup can be damaged by elec-

trostatic charge caused by your clothes and body. Make sure

to avoid electrostatic charges on your clothes or body, or dis-

charge static electricity before handling the optical pickup.

11-1. Laser diode

The laser diode terminals are shorted for transportation in or-

der to prevent electrostatic damage. After replacement, open

the shorted circuit. When removing the pickup from the mecha-

nism, short the terminals by soldering them to prevent this

damage.

11-2. Actuator

The actuator has a powerful magnetic circuit. If a magnetic

material is put close to it. Its characteristics will change. En-

sure that no foreign substances enter through the ventilation

slots in the cover.

11-3. 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.

CAUTION

Use of controls, adjustments, or performance of procedures other

than those specified herein, may result in hazardous radiation ex-

posure.

The compact disc player should not be adjusted or repaired by a-

nyone except properly qualified service personnel.

TROUBLESHOOTING

Power does not turn on. (No sound is produced).

CauseProblem Measure

Fuse is blown. Replace with a fuse of the same amperage as the

old fuse.

Compact disc cannot be loaded.

Sound skips or is noisy .

Sound is bad directly after power is turned on.

Nothing happens when buttons are pressed. Display is not accurate.

Incorrect wiring

Another compact disc is already loaded.

Compact disc is dirty .

Compact disc is heavily scratched or warped.

Water droplets may form on the internal lens when the car is parked in a humid place.

The microprocessor has malfunctioned due to noise, etc.

DCP or main unit connectors are dirty .

Read the attached “Installation/Wire connection Guide” once again and wire properly.

Eject the compact disc before loading the new one.

Clean the compact disc with a soft cloth.

Replace with a compact disc with no scratches.

Let dry for about 1 hour with the power on.

Turn off the power, then press the button and remove the DCP. Press the reset button for about 2 seconds with a thin rod.

Wipe the dirt off with a soft cloth moistened with cleaning alcohol.

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.

Error Display

ERROR 2

ERROR 3

ERROR 6

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

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 disc

This indicates that the CD’s TOC (table of contents) cannot be read, because the selected disc is upside-down.
