SERVICE NOTES

NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK
OR BASE UNIT

The laser diode in the optical pick-up block may suffer electrostatic
breakdown because of the potential difference generated by the
charged electrostatic load, etc. on clothing and the human body.
During repair, pay attention to electrostatic breakdown and also use
the procedure in the printed matter which is included in the repair
parts.
The flexible board is easily damaged and should be handled with
care.

NOTES ON LASER DIODE EMISSION CHECK

The laser beam on this model is concentrated so as to be focused on
the disc reflective surface by the objective lens in the optical pick­up block. Therefore, when checking the laser diode emission, ob­serve from more than 30 cm away from the objective lens.

Notes on Chip Component Replacement

• Never reuse a disconnected chip component.

• Notice that the minus side of a tantalum capacitor may be dam-

aged by heat.

This label is located on the bottom of the chassis.

This label is located on the drive unit’s internal chassis.

When replacing the chassis (T) of mechanism deck which have
the “CAUTION LABEL” attached, please be sure to put a new
CAUTION LABEL (3-223-913-11) to the chassis (T).

NOTE FOR THE OPENING OF THE FRONT PANEL

In this set, the front panel is lowered to below the bottom face when
it is opened.
When servicing the set, place it on a stand having a height of about
2 cm.

Notes on CD-R/CD-RW discs

• You can play CD-Rs (recordable CDs)/CD-RWs (rewr itable CDs)
designed for audio use on this unit.
Look for these marks to distinguish CD-Rs/CD-RWs for audio
use.

These marks denote that a disc is not for audio use.

• Some CD-Rs/CD-RWs (depending on the equipment used for
its recording or the condition of the disc) may not play on this
unit.

• You cannot play a CD-R/a CD-RW that is not finalized∗.

∗ A process necessary for a recorded CD-R/CD-RW disc to be

played on the audio CD player.

Connection diagram (3)

1

To a metal surface of the car

First connect the black ground lead, then connect
the yellow and red power input leads.

2

To the power antenna control lead or power
supply lead of antenna booster amplifier

Notes

• It is not necessary to connect this lead if there is no
power antenna or antenna booster, or with a
manually-operated telescopic antenna.

•When your car has a built-in FM/AM antenna in
the rear/side glass, see “Notes on the control and
power supply leads.”

3

To AMP REMOTE IN of an optional power
amplifier

This connection is only for amplifiers. Connecting
any other system may damage the unit.

4

To the interface cable of a car telephone

5

To a car’s illumination signal

Be sure to connect the black ground lead to a metal
surface of the car.

6

To the +12 V power terminal which is energized
in the accessory position of the ignition key
switch

Notes

• If there is no accessory position, connect to the +12
V power (battery) terminal which is energized at
all times.
Be sure to connect the black ground lead to a
metal surface of the car.

•When your car has a built-in FM/AM antenna in
the rear/side glass, see “Notes on the control and
power supply leads.”

7

To the +12 V power terminal which is energized
at all times

Be sure to connect the black ground lead to a metal
surface of the car.

Notes on the control and power supply leads

• The power antenna control lead (blue) supplies +12 V
DC when you turn on the tuner .

•When your car has built-in FM/AM antenna in the rear/
side glass, connect the power antenna control lead
(blue) or the accessory power input lead (red) to the
power terminal of the existing antenna booster. For
details, consult your dealer.

•A power antenna without relay box cannot be used
with this unit.

Memory hold connection

When the yellow power input lead is connected, power
will always be supplied to the memory circuit even when
the ignition key is turned off.

Notes on speaker connection

• Before connecting the speakers, turn the unit off.

•Use speakers with an impedance of 4 to 8 ohms, and
with adequate power handling capacities to avoid its
damage.

•Do not connect the speaker terminals to the car
chassis, or connect the terminals of the right speakers
with those of the left speaker.

•Do not connect the ground lead of this unit to the
negative (–) terminal of the speaker.

•Do not attempt to connect the speakers in parallel.

•Connect only passive speakers. Connecting active
speakers (with built-in amplifiers) to the speaker
terminals may damage the unit.

•To avoid a malfunction, do not use the built-in speaker
wires installed in your car if the unit shares a common
negative (–) lead for the right and left speakers.

•Do not connect the unit’s speaker cords to each other.

Note on connection

If speaker and amplifier are not connected correctly,
“Failure” appears in the display. In this case, make sure
the speaker and amplifier are connected correctly.

Schéma de raccordement (3)

1

À un point métallique de la voiture

Branchez d‘abord le fil de masse noir et, ensuite, les fils d‘entrée
d‘alimentation jaune et rouge.

2

Vers le fil de commande de l‘antenne électrique ou le fil
d‘alimentation de l‘amplificateur d‘antenne

Remarques

• Il n'est pas nécessaire de raccorder ce fil s'il n'y a pas
d'antenne électrique ni d'amplificateur d'antenne, ou avec
une antenne télescopique manuelle.

•Si votre voiture est équipée d'une antenne FM/AM intégrée
dans la vitre arrière/latérale, voir “Remarques sur les fils de
commande et d'alimentation”.

3

Au niveau du AMP REMOTE IN de l’amplificateur de
puissance en option

Ce raccordement s’applique uniquement aux amplificateurs. Le
branchement de tout autre système risque d’endommager
l’appareil.

4

Vers le cordon de liaison d’un téléphone de voiture

5

Vers le connecteur du signal d’éclairage de la voiture

Raccordez d‘abord le fil de masse noir à un point métallique de
la voiture.

6

À la borne +12 V qui est alimentée quand la clé de contact
est sur la position accessoires

Remarques

•S'il n'y a pas de position accessoires, raccordez la borne
d'alimentation (batterie) +12 V qui est alimentée en
permanence.
Raccordez d‘abord le fil de masse noir à un point métallique
de la voiture.

•Si votre voiture est équipée d'une antenne FM/AM intégrée
dans la vitre arrière/latérale, voir “Remarques sur les fils de
commande et d'alimentation”.

7

À la borne +12 V qui est alimentée en permanence

Raccordez d‘abord le fil de masse noir à un point métallique de
la voiture.

Remarques sur les fils de commande et d'alimentation

• Le fil de commande de l’antenne électrique (bleu) fournit une
alimentation de + 12 V CC lorsque vous mettez la radio sous
tension.

• Lorsque votre voiture est équipée d’une antenne FM/AM intégrée
dans la vitre arrière/latérale, raccordez la sortie de commande de
l’antenne (bleu) ou l’entrée d’alimentation des accessoires (rouge)
à la borne de l’amplificateur d’antenne existant. Pour plus de
détails, consultez votre détaillant.

• Une antenne électrique sans boitier de relais ne peut pas être
utilisée avec cet appareil.

Raccordement pour la conservation de la mémoire

Lorsque le fil d’entrée d’alimentation jaune est raccordé, le circuit
de la mémoire est alimenté en permanence même si la clé de
contact est sur la position d’arrêt.

Remarques sur le raccordement des haut-parleurs

•Avant de raccorder les haut-parleurs, mettez l’appareil hors
tension.

•Utilisez des haut-parleurs ayant une impédance de 4 à 8 ohms
avec une capacité électrique adéquate pour éviter de les
endommager.

• Ne raccordez pas les bornes du système de haut-parleur au châssis
de la voiture et ne raccordez pas les bornes du haut-parleur droit
à celles du haut-parleur gauche.

• Ne raccordez pas le câble de masse de cet appareil à la borne
négative (–) de l’enceinte.

•N’essayez pas de raccorder les haut-parleurs en parallèle.

• Raccordez uniquement des haut-parleurs passifs. Le raccordement
de haut-parleurs actifs (avec amplificateurs intégrés) aux bor nes
des haut-parleurs peut endommager l’appareil.

•Pour éviter tout dysfonctionnement, n’utilisez pas les fils des haut­parleurs intégrés installés dans votre voiture si l’appareil partage
un fil négatif commun (–) pour les haut-parleurs droit et gauche.

• Ne raccordez pas entre eux les cordons des haut-parleurs de
l’appareil.

Remarque sur le raccordement

Si les enceintes et l’amplificateur ne sont pas raccordés
correctement, le message “Failure” s’affiche. Dans ce cas, assurez­vous que les enceintes et l’amplificateur sont bien raccordés.
