QC-6824B-A
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, bond-
ing, 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 inspec-
tion.
If extended damage is caused due to negligence during re-
pair, the legal responsibility shall be with the repairing com-
pany.
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 re-
paired 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 con-
nected, a short circuit and/or fire may occur. If extensive dam-
age is caused due to negligence of repair, the legal responsi-
bility shall be with the repairing company.
5. Cautions in soldering
Please do not spread liquid flux in soldering.
Please do not wash the soldering point after soldering.
6. Cautions in soldering for chip capacitors
Please solder the chip capacitors after pre-heating for replace-
ment because they are very weak to heat.
Please do not heat the chip capacitors with a soldering iron
directly.
7. Cautions in handling for chip parts.
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, tran-
sistors, etc).
Please make an operation test after replacement.
8. 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.

9. Turn the unit OFF during disassembly and parts replacement.
Recheck all work before you apply power to the unit.
10.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
from the lens. Prolonged viewing of the laser within 30cms
may damage your eyesight.
11.Cautions in handling the optical pickup
The laser diode of the optical pickup can be damaged by elec-
trostatic charge caused by your clothes and body. Make sure
to avoid electrostatic charges on your clothes or body, or dis-
charge static electricity before handling the optical pickup.
11-1. Laser diode
The laser diode terminals are shorted for transportation in or-
der to prevent electrostatic damage. After replacement, open
the shorted circuit. When removing the pickup from the mecha-
nism, short the terminals by soldering them to prevent this
damage.
11-2. Actuator
The actuator has a powerful magnetic circuit. If a magnetic
material is put close to it. Its characteristics will change. En-
sure that no foreign substances enter through the ventilation
slots in the cover.
11-3. 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.
ERROR DISPLAYS
If an error occurs, one of the following displays is displayed. Take the measures described below to solve the problem.
DVD
Player
CD
Changer
If an error display other than the ones described above appears, press the Reset button. If the problem
persists, turn off the power and consult your store of purchase.
* When the Reset button is pressed, frequencies of radio stations, titles, etc. stored in memory are cleared.
Displa y Cause Measure
ERROR 2 A disc is caught inside the
CD deck and is not ejected.
This is a failure of DVD deck’s mechanism.
ERROR 3 A disc cannot be played
due to scratches, etc.
Replace with a non-scratched, non-warped disc.
ERROR 6 A disc is loaded upside-
down inside the DVD deck
and does not play.
Eject the disc then reload it properly.

WRONG REGION Region code error Eject the disc, and replace correct region code
disc.
DRM WMA files protected by
DRM are played.
Perform the operation such as skipping a file.
(Scan, repeat and random playback mode may be
canceled.)
NOT SUPPORT Files not supported by this
unit are played.
ERROR 2 A disc inside the CD
changer is not loaded.
This is a failure of CD changer’s mechanism.
ERROR 3 A disc inside the CD
changer cannot be played
due to scratches, etc.
Replace with a non-scratched, non-warped disc.
ERROR 6 A disc inside the CD
changer cannot be played
because it is loaded
upside-down.
Eject the disc then reload it properly.
