■CAUTION

This equipment has been tested and found to comply with
the limits for a Class B digital device, pursuant to Part 15 of
the FCC Rules.These limits are designed to provide rea­sonable protection against harmful interference in a resi­dential installation.This equipment generates,uses,and can
radiate radio frequency energy and,if not installed and used
in accordance with the instructions,may cause harmful in­terference to radio communications.However,there is no
quarantee that interference will not occur in a particular
installation.If this equipment does cause harmful interfer­ence to radio or television reception,which can be deter­mined by turning the equipment off and on,the user is en­couraged to consult the dealer or an experienced radio/TV
technician for help.

This appliance contains a laser system and is classified as
a "CLASS 1 LASER PRODUCT".To use this model
properly,read this Owner's Manual carefully and keep this
manual for your future reference.In case of any trouble with
this player,please contact your nearest "AUTHORIZED ser­vice station".To prevent direct exposure to the laser beam,do
not try to open the enclosure.

■ 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

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 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
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.

℃. Take care not to

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 isopropylalcohol
to lens paper and wipe the lens gently.

■ERROR DISPLAYS
