ELECTRICAL CONNECTIONS
To prevent short circuits, we recommend that you disconnect the
battery’s negative terminal and make all electrical connections
before installing the unit. If you are not sure how to install this unit
correctly, have it installed by a qualified technician.
Note:
This unit is designed to operate on 12 volts DC NEGATIVE
ground electrical systems . If your vehicle does not have this
system, a voltage inverter is required, which can be purchased at
JVC car audio dealers.
•Replace the fuse with one of the specified rating. If the fuse
blows frequently, consult your JVC car audio dealer.
•If noise is a problem...
This unit incorporates a noise filter in the power circuit.However,
with some vehicles, clicking or other unwanted noise may occur.
If this happens, connect the unit’s rear ground terminal (See
connection diagram below.) to the car’s chassis using shorter
and thicker cords, such as copper braiding or gauge wire. If noise
still persists, consult your JVC car audio dealer.
•Maximum input of the speakers should be more than 40 watts at
the rear and 40 watts at the front, with an impedance of 4 to 8
ohms.
•Be sure to ground this unit to the car’s chassis.
•The heat sink becomes very hot after use. Be careful not to
touch it when removing this unit.
ESPAÑOL
CONEXIONES ELECTRICAS
Para evitar cortocircuitos, recomendamos que desconecte el

RACCORDEMENTS ELECTRIQUES
Pour éviter tout court-circuit, nous vous recommandons de
débrancher la borne négative de la batterie et d’effectuer tous les
raccordements électriques avant d’installer l’appareil. Si l'on n’est
pas sûr de pouvoir installer correctement cet appareil, le faire
installer par un technicien qualifié.
Remarque:
Cet appareil est conçu pour fonctionner sur des sources de courant
continu de
12 volts à mas s e NEGATIVE . Si votre véhicule n’offre
pas ce type d’alimentation, il vous faut un convertisseur de tension,
que vous pouvez acheter chez un revendeur d’autoradios JVC.
• Remplacer le fusible par un de la valeur précisée. Si le fusible
saute souvent, consulter votre revendeur d’autoradios JVC.
• Si le bruit est un problème...
Cet appareil incorpore un filtre de bruit dans le circuit
d’alimentation. Cependant, avec certains véhicules, quelques
claquements ou autres bruits non désirés risquent de se produire.
Si cela arrive, raccorder la
borne de mas s e arrière de l’appareil
au châssis de la voiture (voir le schéma de raccordement ci-
dessous) en utilisant des cordons les plus gros et les plus courts
possibles telle qu'une barre de cuivre ou une tresse. Si le bruit
persiste, consulter votre revendeur d’autoradios JVC.
• La puissance admissible des haut-parleurs doit être supérieure
à40 watts àl’arrière et à40 watts l’avant, avec une impédance
de
4 à 8 ohms .
• S'assurer de raccorder la mise à la masse de cet appareil
au châssis de la voiture.
•
Le radiateur devient très chaud après usage. Faire attention de
ne pas le toucher en retirant cet appareil.
