Schéma de raccordement
À un point métallique de la voiture
Branchez d’abord le câble de mise à la masse noir et, ensuite, les
câbles d’entrée d’alimentation jaune et rouge.
Vers le câble de commande d’antenne électrique
ou vers le câble d’alimentation de l’amplificateur
d’antenne
Remarques
• Il n’est pas nécessaire de raccorder ce câble 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 câbles de
commande et d’alimentation ».
Au niveau de 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.
Vers le cordon de liaison d’un téléphone de voiture
Vers le connecteur du signal d’éclairage de la
voiture
Raccordez d’abord le câble de mise à la masse noir à un point
métallique du véhicule.
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 câble de mise à la masse noir à un point
métallique du véhicule.
• Si votre voiture est équipée d’une antenne FM/AM intégrée
dans la vitre arrière/latérale, voir « Remarques sur les câbles de
commande et d’alimentation ».
À la borne +12 V qui est alimentée en
permanence
Raccordez d’abord le câble de mise à la masse noir à un point
métallique du véhicule.
Remarques sur les câbles de commande et d’alimentation
• Le câble de commande d’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 le câble de commande
d’antenne électrique (bleu) ou le câble d’alimentation des
accessoires (rouge) à la borne d’alimentation de l’amplificateur
d’antenne existant. Pour plus de détails, consultez votre détaillant.
• Une antenne électrique sans boîtier de relais ne peut pas être
utilisée avec cet appareil.
Raccordement pour la conservation de la mémoire
Lorsque le câble 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-parleurs 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 mise à la masse de cet appareil à la
borne négative (–) du haut-parleur.
• 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 bornes
des haut-parleurs peut endommager l’appareil.
• Pour éviter tout problème de fonctionnement, n’utilisez pas les
câbles des haut-parleurs intégrés installés dans votre voiture si
l’appareil possède un câble 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 haut-parleurs et l’amplificateur ne sont pas raccordés
correctement, le message « Failure » s’affiche. Dans ce cas, assurez-
vous que les haut-parleurs et l’amplificateur sont bien raccordés.
Connection diagram
To a metal surface of the car
First connect the black ground (earth) lead, then connect the
yellow and red power supply leads.
To the power antenna (aerial) control lead or
power supply lead of antenna (aerial) booster
Notes
• It is not necessary to connect this lead if there is no power
antenna (aerial) or antenna (aerial) booster, or with a
manually-operated telescopic antenna (aerial).
• When your car has a built-in FM/AM antenna (aerial) in the
rear/side glass, see “Notes on the control and power supply
leads.”
To AMP REMOTE IN of an optional power
amplifier
This connection is only for amplifiers. Connecting any other
system may damage the unit.
To the interface cable of a car telephone
To a car’s illumination signal
Be sure to connect the black ground (earth) lead to a metal
surface of the car first.
To the +12 V power terminal which is
energized in the accessory position of the
ignition 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 (earth) lead to a metal
surface of the car first.
• When your car has a built-in FM/AM antenna (aerial) in the
rear/side glass, see “Notes on the control and power supply
leads.”
To the +12 V power terminal which is
energized at all times
Be sure to connect the black ground (earth) lead to a metal
surface of the car first.
Notes on the control and power supply leads
• The power antenna (aerial) control lead (blue) supplies +12 V
DC when you turn on the tuner.
• When your car has built-in FM/AM antenna (aerial) in the rear/side
glass, connect the power antenna (aerial) control lead (blue) or
the accessory power supply lead (red) to the power terminal of the
existing antenna (aerial) booster. For details, consult your dealer.
• A power antenna (aerial) without a relay box cannot be used
with this unit.
Memory hold connection
When the yellow power supply lead is connected, power will
always be supplied to the memory circuit even when the ignition
switch 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 (earth) 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 leads
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 leads 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.
