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.
