NOTE* We cannot supply PWB with component parts in prin-

ciple. When a circuit on PWB has failure, please repairit by component parts base. Parts which are not men-tioned in service manual are not supplied.

* This unit is used the special adjustment jig for measur-ing.

* Dolby noise reduction manufactured under license fromDolby Laboratories Licensing Corporation.

* "DOLBY" and the double-D symbol are trademarks ofDolby Laboratories Licensing Corporation.

* Specifications and design are subject to change withoutnotice for further improvement.

To engineers in charge of repair orinspection of our products.Before repair or inspection, make sure to follow theinstructions so that customers and Engineers incharge of repair or inspection can avoid sufferingany risk or injury.

1. Use specified parts.The system uses parts with special safety features againstfire and voltage. Use only parts with equivalent character-istics when replacing them.The use of unspecified parts shall be regarded as remod-eling for which we shall not be liable. The onus of productliability (PL) shall not be our responsibility in cases wherean accident or failure is as a result of unspecified partsbeing used.

2. Place the parts and wiring back in their original positionsafter 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 us-ing clamps to keep away from heated and high voltageparts. Ensure that they are placed back in their originalpositions after repair or inspection.If extended damage is caused due to negligence duringrepair, the legal responsibility shall be with the repairingcompany.

3. Check for safety after repair.Check that the screws, parts and wires are put back se-curely in their original position after repair. Ensure for safetyreasons there is no possibility of secondary ploblemsaround 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 theparts for the automobile.Disconnect the battery terminal after turning the ignitionkey off. If wrong wiring connections are made with the bat-tery connected, a short circuit and/or fire may occur. If ex-tensive damage is caused due to negligence of repair, thelegal responsibility shall be with the repairing company.

5. Cautions regarding chips.Do not reuse removed chips even when no abnormality isobserved in their appearance. Always replace them withnew ones. (The chip parts include resistors, capacitors,diodes, transistors, etc). The negative pole of tantalumcapacitors is highly susceptible to heat, so use special carewhen replacing them and check the operation afterwards.

6. Cautions in handling flexible PWBBefore working with a soldering iron, make sure that theiron tip temperature is around 270 . Take care not to ap-ply the iron tip repeatedly(more than three times)to thesame patterns. Also take care not to apply the tip with force.

7. Turn the unit OFF during disassembly and parts replace-ment. 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 throughthe lens of the optical pickup. When checking that the la-ser optical diode lights up, keep your eyes more than 30cmsaway from the lens. Prolonged viewing of the laser within30cms may damage your eyesight.

9. Cautions in handling the optical pickupThe laser diode of the optical pickup can be damaged byelectrostatic charge caused by your clothes and body. Makesure to avoid electrostatic charges on your clothes or body,or discharge static electricity before handling the opticalpickup.

9-1. Laser diodeThe laser diode terminals are shorted for transporta-tion in order to prevent electrostatic damage. Afterreplacement, open the shorted circuit. When remov-ing the pickup from the mechanism, short the termi-nals by soldering them to prevent this damage.

9-2. ActuatorThe actuator has a powerful magnetic circuit. If amagnetic material is put close to it. Its characteris-tics will change. Ensure that no foreign substancesenter through the ventilation slots in the cover.

9-3. Cleaning the lensDust on the optical lens affects performance. Toclean the lens, apply a small amount of isopropylalcohol to lens paper and wipe the lens gently.

COMPUTER ANTI-THEFT SYSTEMThis unit has a built-in Computer Anti-theft System(CATS).RELEASE the CATS1. Turn power on.Then "SAFE" is indicated for 3

second.And then it change to indicate "1000".2. Input code by M1 to M4 preset buttons.After selected

code,press SEEK up or SCAN button more than 2second.Then beep sound is made.And then a unit work.

3. If wrong code is inputed 2 times,a unit will be lock by aunit changes code input mode,it waits with power supplyfor about 1 hour.

4. After lock 1 hour with power supply,it will be changedcode input mode.When wrong code is inputed twice, aunit will be lock mode.

CAUTIONSUse of controls,adjustment,or performance of proceduresother than those specified herein,may result in hazardousradiation exposure.The compact disc player should not be adjusted or repairedby anyone except properly qualified service personnel.
