1. Use specified parts.

The system uses parts with special safety features against

fire and voltage. Use only parts with equivalent charac-

teristics 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.

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 con-

nection 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 se-

curely 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 re-

pair, 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 com-

pany.

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 suffer-

ing any risk or injury.

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, capaci-

tors, diodes, transistors, etc). The negative pole of tanta-

lum capacitors is highly susceptible to heat, so use spe-

cial 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 . 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 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 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 la-

ser 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 transpor-

tation 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 characteris-

tics 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.
