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.

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.

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.

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.

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.

Cautions in soldering

Please do not spread liquid flux in soldering. Please do

not wash the soldering point after soldering.

Cautions in soldering for chip capacitors

Please solder the chip capacitors after pre-heating for

replacement because they are very weak to heat. Please

do not heat the chip capacitors with a soldering iron

directly.

Cautions in handling for chip parts.

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). Please make an operation test

after replacement.

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.

Turn the unit OFF during disassembly and parts

replacement.

Recheck all work before you apply power to the unit.

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.

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.

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.

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.

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.
