To engineers in charge of repair or inspe-
ction of our products.
Before repair or inspection, make sure to follow the in-
structions 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 fi-
re and voltage. Use only parts with equivalent characteristics
when replacing them.
The use of unspecified parts shall be regarded as remodeli-
ng for which we shall not be liable. The onus of product liab-
ility (PL) shall not be our responsibility in cases where an ac-
cident or failure is as a result of unspecified parts being used.
2. Place the parts and wiring back in their original positions aft-
er replacement or rewiring.
For proper circuit construction, use of insulation tubes, bon-
ding, 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 rep-
air 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 reas-
ons there is no possibility of secondary ploblems 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 co-
nnected, a short circuit and/or fire may occur. If extensive da-
mage is caused due to negligence of repair, the legal respon-
sibility shall be with the repairing company.
5. Cautions regarding chips.
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). The negative pole of tantalum capacitors is
highly susceptible to heat, so use special care when replacing
them and check the operation afterwards.
6. Cautions in handling flexible 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 patt-
erns. Also take care not to apply the tip with force.
7. Turn the unit OFF during disassembly and parts replacement.
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 opti-
cal diode lights up, keep your eyes more than 30cms away fr-
om the lens. Prolonged viewing of the laser within 30cms m-
ay damage your eyesight.
9. Cautions in handling the optical pickup
The laser diode of the optical pickup can be damaged by ele-
ctrostatic charge caused by your clothes and body. Make su-
re to avoid electrostatic charges on your clothes or body, or
discharge static electricity before handling the optical pickup.
9-1. 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.
9-2. Actuator
The actuator has a powerful magnetic circuit. If a magnet-
ic material is put close to it. Its characteristics will change.
Ensure that no foreign substances enter through the ventil-
ation 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 isopropyl alcohol to lens pa-
per and wipe the lens gently.
CAUTIONS
Use of controls, adjustment, or performance of procedures other
than those specified herein, may result in hazardous radiation
exposure.
The compact disc player should not be adjusted or repaired by
anyone except properly qualified service personnel.
