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, bonding, 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 inspection. If extended damage is caused due to negligence during repair, the legal responsibility shall be with the repairing company.

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 problems around the repaired 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 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 repairing company.

5. Cautions regarding chips. Do not reuse removed chips even when no abnormality is observed in their appearance. Always replace them with new ones. (The chip parts include resistors, capacitors, 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.

6. 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.

7. Turn the unit OFF during disassembly and parts replacement. Recheck all work before you apply power to the unit.

8. 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 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.

CAUTIONS

Use of controls, adjustments, or performance of procedures other those specified herein, may resault in hazardous radiation exposure. The compact disc player should not be adjustment or repaired by anyone expext properly qualified service personnel.

TROUBLESHOOTING

Power does not turn on (or no sound is produced).

MAIN UNIT SECTION

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.

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.

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.

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

CD ER2

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

Corrective Measure

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

CD ER6

disc or some other factor during source unit play.

-Check the compact unit

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