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.

UNLEADED SOLDER

•

Boards requiring use of unleaded solder are printed with the leadfree mark (LF) indicating the solder contains no lead. (Caution:Some printed circuit boards may not come printed with

the lead free mark due to their particular size.)

: LEAD FREE MARK

Unleaded solder has the following characteristics.

• Unleaded solder melts at a temperature about 40°C higher than ordinary solder. Ordinary soldering irons can be used but the iron tip has to be applied to the solder joint for a slightly longer time. Soldering irons using a temperature regulator should be set to about 350°C. Caution:The printed pattern (copper foil) may peel away if the

heated tip is applied for too long, so be careful!

• Strong viscosity Unleaded solder is more viscous (sticky, less prone to flow) than ordinary solder so use caution not to let solder bridges occur such as on IC pins, etc.

• Usable with ordinary solder It is best to use only unleaded solder but unleaded solder may also be added to ordinary solder.

l’amplifi cateur de puissance en option

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

4 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 ».

5 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 (bleu) ou le câble d’alimentation des accessoires (rouge) à la borne d’alimentation de l’amplifi cateur d’antenne existant.

•

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 hautparleur 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 amplifi cateurs 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 partage un câble négatif commun (–) pour les hautparleurs droit et gauche.

•

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

Remarque sur le raccordement

Si les haut-parleurs ne sont pas raccordés correctement, le message « FAILURE » s’affi che. Dans ce cas, assurez-vous que les haut-parleurs sont bien raccordés.
