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 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.

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 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 abnormal­ity is observed 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 patterns. 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 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 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.

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
magnetic material is put close to it. Its characteristics
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 isopropyl alcohol to
lens paper and wipe the lens gently.

CAUTIONS

Use of controls, adjustments, or performance of
procedures other those specified herein, may resault in
hazardous radiation exposure.
The compact disc player should not be adjustment or
repaired by anyone expext properly qualified service
personnel.

ER3

This error display indicates that a fault has arisen in the mechanism of the
source unit (for example, the disc cannot be ejected).

-Check the source unit

This error display indicates that the pickup focus is off because of a scratched
disc or some other factor during source unit play.

-Check the compact unit

Corrective Measure

ER6

This indicates that the CD’s TOC (table of contents) cannot be read, because
the selected disc is upside-down.
