DB188/189RMP/DB189RGMP

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 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 con-

nected, 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 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, tran­sistors, 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 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.

11. 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.

11-1. 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.

11-2. 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.

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.

CAUTION

This appliance contains a laser system and is classified as a

"CLASS 1 LASER PRODUCT". 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.

NOTES OF ISO CONNECTOR

1. For VW and Audi vehicles, change the position of fuse
installation as shown on the diagram.(Figure 1)

ISO CONNECTOR type

For other vehicles (initial position)

FUSE
(15A)

Main unit side ISO connector

Figure 1

2. When the car stereo is installed in 1998 and later Volkswagen
models, make sure to cut the car lead wire connected the A-5
terminal. (A breakdown could occur if the lead wire is not cut.)
After cutting the lead wire, isulate the front end of the lead wire

with insulation tape to prevent the risk of short-circuits.(Figure 2 )

Note: Before cutting the lead wire, disconnect the car battery --

(negative) cable.

3. When the main unit is also connected to an external amplifier,
connect REMOTE on the external amplifier to the previously
cut lead wire on the side of the connector.

TROUBLESHOOTING

Problem

Power does not turn on.

a disc.

Files are not recognized as an

MP3/WMA file.

File system is not correct. Use ISO9660 level 1,2 or JOLIET or Romeo file system.

1. Turn the unit off.

2. Remove all wires attached to the power antenna lead. Check

each wire for a possible short to ground using an ohm meter.

3.Turn the unit back on.

4. Reconnect each amplifier remote wire to the power antenna lead

one by one. If the amplifiers turn off before all wires are attached,

use an external relay to provide remote-on voltage

(excessive current required).

Turn off the power, then press the

[RELEASE] button and remove the DCP.

Press the reset button for about 2 seconds

with a thin rod.

Wipe the dirt off with a soft cloth moistened with cleaning alcohol.

Turn down sound volume. Function can also be restored by turning

the power off and on again.

(Speaker volume is reduced automatically when the speaker prote-

ction circuit operates).

Write MP3/WMA files onto the disc properly.

Use MP3/WMA files encoded properly.

Reset button

Sound skips or is noisy. Compact disc is dirty.

Compact disc is heavily scratch-

ed or warped.

Sound is cut or skipped.

Noise is generated or noise

is mixed with sound.

Sound is bad directly after

power is turned on.

Wrong filename File system is not correct. Use ISO9660 level 1, 2 or JOLIET or Romeo file system.

MP3/WMA files are not

encoded properly.

Water droplets may form on

the internal lens when the car

is parked in a humid place.

Clean the disc with a soft cloth.

Replace with a disc with no scratches.

Use MP3/WMA files encoded properly.

Let dry for about 1 hour with the power on.

ERROR DISPLAYS

If an error occurs, one of the following displays is displayed. Take the measures described below to eliminate the problem.

Error Display Cause Measure

ERROR 2

ERROR 3 A CD cannot be played due to scratches, etc. Replace with a non-scratched, non-warped disc.

ERROR 6

A CD is caught inside the CD deck and is not

ejected.

A CD is loaded upside-down inside the CD deck

and does not play.

This is a failure of CD deck's mechanism.

Eject the disc then reload it properly.
