SERVICE NOTES
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.
Notes on Chip Component Replacement
• Never reuse a disconnected chip component.
• Notice that the minus side of a tantalum capacitor may be dam-
aged by heat.
E Model
CLASS 1
CAUTION
Use of controls or adjustments or performance of procedures
other than those specified herein may result in hazardous
radiation exposure.
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 f low)
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.

Connection diagram (3)
1
To a metal surface of the car
First connect the black ground lead, then connect
the yellow and red power input leads.
2
To the power antenna control lead or power
supply lead of antenna booster amplifier
Notes
• It is not necessary to connect this lead if there is no
power antenna or antenna booster, or with a
manually-operated telescopic antenna.
•When your car has a built-in FM/AM antenna in
the rear/side glass, see “Notes on the control and
power supply leads.”
3
To AMP REMOTE IN of an optional power
amplifier
This connection is only for amplifiers. Connecting
any other system may damage the unit.
4
To the interface cable of a car telephone
5
To 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.”
6
To 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 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 key is turned off.
Notes on speaker connection
•Before connecting the speakers, tur n 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 amplifiers) to the speaker
terminals may damage the unit.
•To avoid a malfunction, do not use the built-in speaker
wires 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 cords to each other.
Note on connection
If speaker and amplifier are not connected correctly,
"FAILURE" appears in the display. In this case, make sure
the speaker and amplifier are connected correctly.
Schéma de raccordement (3)
1
À un point métallique de la voiture
Branchez d‘abord le fil de masse noir et, ensuite, les
fils d‘entrée d‘alimentation jaune et rouge.
2
Vers le fil de commande de l‘antenne électrique
ou le fil d‘alimentation de l‘amplificateur
d‘antenne
Remarques
• Il n'est pas nécessaire de raccorder ce fil 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 fils de commande et
d'alimentation”.
3
Au niveau du 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.
4
Vers le cordon de liaison d’un téléphone de
voiture
5
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 fil de masse noir à un point
métallique de la voiture.
• Si votre voiture est équipée d'une antenne FM/AM
intégrée dans la vitre arrière/latérale, voir
“Remarques sur les fils de commande et
d'alimentation”.
6
À
la borne +12 V qui est alimentée en
permanence
Raccordez d‘abord le fil de masse noir à un point
métallique de la voiture.
Remarques sur les fils de commande et
d'alimentation
• Le fil de commande de l’antenne électr ique (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 la
sortie de commande de l’antenne (bleu) ou l’entrée
d’alimentation des accessoires (rouge) à la borne de
l’amplificateur d’antenne existant. Pour plus de détails,
consultez votre détaillant.
•Une antenne électrique sans boitier de relais ne peut
pas être utilisée avec cet appareil.
Raccordement pour la conservation de la mémoire
Lorsque le fil 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-par leurs ayant une impédance de 4 à
8ohms avec une capacité électrique adéquate pour
éviter de les endommager.
•Ne raccordez pas les bornes du système de hautparleur au châssis de la voiture et ne raccordez pas les
bornes du haut-parleur droit à celles du haut-parleur
gauche.
•Ne raccordez pas le câble de masse de cet appareil à la
borne négative (–) de l’enceinte.
•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
fils des haut-parleurs intégrés installés dans votre
voiture si l’appareil partage un fil négatif commun (–)
pour les haut-parleurs droit et gauche.
•Ne raccordez pas entre eux les cordons des hautparleurs de l’appareil.
Remarque sur le raccordement
Si les enceintes et l’amplificateur ne sont pas raccordés
correctement, le message “FAILURE” s’affiche. Dans ce
cas, assurez-vous que les enceintes et l’amplificateur sont
bien raccordés.
