•UNLEADED SOLDERBoards 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 beapplied to the solder joint for a slightly longer time.Soldering irons using a temperature regulator should be set toabout 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 bridgesoccur such as on IC pins, etc.
• Usable with ordinary solderIt is best to use only unleaded solder but unleaded solder mayalso be added to ordinary solder.
This label is located on the bottom of the chassis.
• CD Playback:You can play CD-DA (also containing CD TEXT*1), CD-R/CD-RW (MP3 WMA files also containing Multi Session and ATRACCD (ATRAC3 and ATRAC3plus format).

Connection diagram
1 To a metal surface of the carFirst connect the black ground lead, then connect the orange/white striped, yellow, and red power input leads.
2 To the power antenna control lead or power supply lead of antenna booster amplifi erNotes• 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 amplifi erThis connection is only for amplifi ers. Connecting any other system may damage the unit.
4 To the interface cable of a car telephone5 To a car’s illumination signal
Be sure to connect the black ground lead to a metal surface of the car fi rst.
6 To the +12 V power terminal which is energized in the accessory position of the ignition key switchNotes• 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 fi rst.• When your car has a built-in FM/AM antenna in the rear/
side glass, see “Notes on the control and power supply leads.”
7 To the +12 V power terminal which is energized at all timesBe sure to connect the black ground lead to a metal surface of the car fi rst.
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 mémoireLorsque 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 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 haut-parleurs droit et gauche.
• Ne raccordez pas entre eux les cordons des haut-parleurs de l’appareil.
Remarque sur le raccordementSi 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.
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 connectionWhen 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 connectionIf speaker and amplifi er are not connected correctly, “FAILURE” appears in the display. In this case, make sure the speaker and amplifi er are connected correctly.
