2. 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 specifi ed parts.
The system uses parts with special safety features against fi re

and voltage. Use only parts with equivalent characteristics when
replacing them.

The use of unspecifi ed 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 unspecifi ed 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 fi re may occur. If extensive damage is
caused due to negligence of repair, the legal responsibility shall
be with the repairing company.

5. Cautions in soldering

Please do not spread liquid fl ux in soldering.
Please do not wash the soldering point after soldering.

6. Cautions in soldering for chip capacitors

Please solder the chip capacitors after pre-heating for replace-

ment because they are very weak to heat.

Please do not heat the chip capacitors with a soldering iron di-

rectly.

7. Cautions in handling for chip parts.

Do not reuse removed chips even when no abnormality is ob-

served 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.

8. Cautions in handling fl exible 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.

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

10. Cautions in checking that the optical pickup lights up.

The laser is focused on the disc refl ection 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

QX-3870N-A

lens. Prolonged viewing of the laser within 30cms may damage
your eyesight.

11. Cautions in handling the optical pickup
The laser diode of the optical pickup can be damaged by elec-

trostatic 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.
11-1. 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.
11-2. Actuator
The actuator has a powerful magnetic circuit. If a magnetic ma-

terial is put close to it. Its characteristics will change. Ensure that

no foreign substances enter through the ventilation slots in the

cover.
11-3. 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.
