Design and specifications are subject to change without
notice.
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 pick-
up 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 damaged
by heat.
TEST DISCS
This set can playback CD-R and CD-ROM discs. The following
test discs should be used to check the capability:
CD-R test disc TCD-R082LMT (Part No. J-2502-063-1)
CD-RW test disc TCD-W082L (Part No. J-2502-063-2)
If the optical pick-up block is defective, please replace the whole
optical pick-up block.
Never turn the semi-fixed resistor located at the side of optical pick-
up block.

•UNLEADED SOLDER
Boards requiring use of unleaded solder are printed with the lead-
free 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.
•CD Playback:
You can play CD-DA (also containing CD TEXT*1), CD-R/CD-
RW (MP3 files also containing Multi Session and ATRAC CD
(ATRAC3 and ATRAC3plus format).
Type of discs Label on the disc

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 ».
3Au 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.
4Vers le cordon de liaison d’un téléphone de
voiture
5Vers 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.
6À 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 ».
7À 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 l’entrée 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’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-parleurs au
châssis de la voiture et ne raccordez pas les bornes des haut-
parleurs 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 dysfonctionnement, n’utilisez pas les câbles des
haut-parleurs intégrés installés dans votre voiture si l’appareil
partage 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
