Before repair or inspection, make sure to follow:
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.
