WHOSE PART NUMBERS APPEAR AS SHOWN IN THIS
MANUAL OR IN SUPPLEMENTS PUBLISHED BY SONY.
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.

•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.

5To a car’s illumination signal
Be sure to connect the black ground lead to a metal surface
of the car first.
6To 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 first.
• When your car has a built-in FM/AM antenna in the rear/
side glass, see “Notes on the control and power supply
leads.”
7To 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 first.
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 a relay box cannot be used with this

de control y de fuente de alimentación”.
7Al terminal de alimentación de +12 V que
recibe energía sin interrupción
Asegúrese de conectar primero el cable de conexión a masa
negro a una superficie metálica del automóvil.
Notas sobre los cables de control y de fuente de
alimentación
• El cable de control de la antena motorizada (azul) suministrará
cc de + 12 V cuando conecte la alimentación del sintonizador.
• Si el automóvil dispone de una antena de FM/AM incorporada
en el cristal trasero o lateral, conecte el cable de control de
antena motorizada (azul) o el cable de entrada de alimentación
auxiliar (rojo) al terminal de alimentación del amplificador de
antena existente. Para obtener más información, consulte a su
distribuidor.
• Con esta unidad no es posible utilizar una antena motorizada
sin caja de relé.
Conexión para protección de la memoria
Si conecta el cable de entrada de alimentación amarillo, el
circuito de la memoria recibirá siempre alimentación, aunque
apague la llave de encendido.
Notas sobre la conexión de los altavoces
• Antes de conectar los altavoces, desconecte la alimentación
de la unidad.
• Utilice altavoces con una impedancia de 4 a 8
Ω con la
capacidad de potencia adecuada para evitar que se dañen.
• No conecte los terminales de altavoz al chasis del automóvil,
ni conecte los terminales del altavoz derecho con los del
izquierdo.
• No conecte el cable de conexión a masa de esta unidad al
terminal negativo (–) del altavoz.
• No intente conectar los altavoces en paralelo.
• Conecte solamente altavoces pasivos. Si conecta altavoces
activos (con amplificadores incorporados) a los terminales de
altavoz, puede dañar la unidad.
• Para evitar fallos de funcionamiento, no utilice los cables de
altavoz incorporados instalados en el automóvil si su unidad
comparte un cable negativo común (–) para los altavoces
derecho e izquierdo.
• No conecte los cables de altavoz de la unidad entre sí.
Nota sobre la conexión
Si el altavoz y el amplificador no están conectados
correctamente, aparecerá “Failure” en la pantalla. Si es así,
compruebe la conexión de ambos dispositivos.
Schéma de raccordement
1À un point métallique de la voiture
Branchez d’abord le fil de masse noir et, ensuite, les fils
d’entrée d’alimentation rayé orange/blanc, jaune, et rouge.
2Vers le câble de commande d’antenne
électrique ou 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 ou 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
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.
