■ 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 ploblems 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
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 isopropylalcohol to
lens paper and wipe the lens gently.
