To engineers in charge of repair
or inspection of our products.
Before repair or inspection, make sure to fol-
low the instructions so that customers and
Engineers in charge of repair or inspection can
avoid suffering any risk or injury.
1. Use specified parts.
The system uses parts with special safety features
against fire and voltage. Use only parts with equiva-
lent 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.
2. Place the parts and wiring back in their original posit-
ions after replacement or re-wiring.
For proper circuit construction, use of insulationtubes,
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 second-
ary ploblems around the repaired spots.
If extended damage is caused due to negligence of
repair, the legal responsibility shall be with the repair-
ing 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 company.
5. Cautions regarding chips.
Do not reuse removed chips even when no abnor-
mality is observed in their appearance. Always re-
place them with new ones. (The chip parts include
resistors, capacitors, diodes, transistors, etc). The nega-
tive pole of tantalum capacitors is highly susceptible
to heat, so use special care when replacing them and
check the operation afterwards.
6. Cautions in handing 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 rep-
lacement. 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 laser within 30cms may damage your
eyesight.
9. Cautions in handing the optical pickup
The laser diode of the optical pickup can be damag-
ed by electrostatic charge caused by your clothes
and body. Make sure to avoid electrostatic charges
on your clothes or body, or discharge static electric
ity 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 characteristi-
cs 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 isopropolal-
cohol to lens paper and wipe the lens gently.
