optical pick-up

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.

*1 A CD TEXT disc is a CD-DA that includes information such as

disc, artist and track name.

EXTENSION CABLE AND SERVICE POSITION

When repairing or servicing this set, connect the jig (extension cable)
as shown below.

• Connect the MAIN board (CN350) and the SERVO board (CN2)

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
unit.

Memory hold connection

When the yellow power input 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 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 amplifi ers) 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 amplifi er are not connected correctly, “FAILURE”

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 l’entrée d’alimentation des
accessoires (rouge) à la borne d’alimentation de l’amplifi cateur
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 haut­parleurs 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 et l’amplifi cateur ne sont pas raccordés
correctement, le message « FAILURE » s’affi che. Dans ce cas,
assurez-vous que les haut-parleurs et l’amplifi cateur sont bien
raccordés.
