SERVICING NOTES
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.
CONFIRMING THE OPERATION
Please confirm the car audio unit works even if REM output is not
connected when you connect this unit with the car audio unit by
the HIGH LEVEL input.
MAIN BOARD DISCRIMINATION
In this unit, the MAIN board has been changed in the midway of
production.

Cautions
Before making any connections, disconnect the ground
terminal of the car battery to avoid short circuits.
Be sure to use speakers with an adequate power rating. If you
use small capacity speakers, they may be damaged.
Do not connect the terminal of the speaker system to the
car chassis, and do not connect the terminal of the right
speaker with that of the le speaker.
Install the input and output cords away from the power
supply wire as running them close together can generate
some interference noise.
is unit is a high powered amplier. erefore, it may not
perform to its full potential if used with the speaker cords
supplied with the car.
If your car is equipped with a computer system for navigation or
some other purpose, do not remove the ground wire from the car
battery. If you disconnect the wire, the computer memory may be
erased. To avoid short circuits when making connections,
disconnect the +12V power supply wire until all the other wires
have been connected. Notes on the power supply
Connect the +12V power supply wire only after all the other
wires have been connected.
Be sure to connect the ground wire of the unit securely to
a metal point of the car. A loose connection may cause a
malfunction of the amplier.
Be sure to connect the remote control wire of the car audio
unit to the remote terminal.
When using a car audio unit without a remote output on the
amplier, connect the remote input terminal (REMOTE) to the
accessory power supply.
Use a power supply wire with a fuse attached (60 A).
All power wires connected to the positive battery post should
be fused within 450 mm (18 in) of the battery post, and
before they pass through any metal.
Make sure that the vehicle’s battery wires connected to the
vehicle are of a wire gauge at least equal to that of the main
power wire connected from the battery to the amplier.
Make sure that the wires to be connected to the +12V and
GND terminals of this unit are at least 4-Gauge (AWG-4) or
have a sectional area of more than 22.0 mm2(7/8in2).
Mount the unit as illustrated.
Montez l’appareil comme illustré.
Monte la unidad tal como se muestra en la
ilustración.
Installation
Before Installation
Mount the unit either inside the trunk or under a seat.
Choose the mounting location carefully so the unit will not
interfere with the normal movements of the driver and it will
not be exposed to direct sunlight or hot air from the heater.
Do not install the unit under the oor carpet, where the heat
dissipation from the unit will be considerably impaired.
First, place the unit where you plan to install it, and mark the
positions of the four screw holes on the surface of the
mounting board (not supplied). en drill the holes
approximately 3 mm (1/8in) in diameter and mount the unit
onto the board with the supplied mounting screws. e
supplied mounting screws are 14 mm (9/16 in) long. erefore,
make sure that the mounting board is thicker than 14 mm
(9/16 in).
*1If you have the factory original or some
other car audio unit without a remote
output for the amplier, connect the
remote input terminal (REMOTE) to the
accessory power supply.
In High level input connection, car audio
unit can also be activated without need for
REMOTE connection. However, this
function is not guaranteed for all car audio
units.

Installation
Avant l’installation
Installez l’appareil dans le core ou sous un siège.
Choisissez un endroit de montage judicieux pour que
l’appareil ne gêne pas les mouvements naturels du
conducteur et pour qu’il ne soit pas exposé aux rayons
directs du soleil ou à proximité d’une bouche d’air chaud.
N’installez pas l’appareil sous le tapis, car cela empêcherait
l’évacuation de la chaleur de l’appareil.
Tout d’abord, mettez l’appareil où vous prévoyez de l’installer
et tracez les quatre trous de vis sur la surface de la plaque de
montage (non fournie). Percez ensuite les trous selon un
diamètre d’environ 3 mm (1/8po) et installez l’appareil sur la
plaque avec les vis de montage fournies. Les vis de montage
fournies font 14 mm (9/16 po) de long. Par conséquent,
assurez-vous que la plaque de montage fait plus de 14 mm
(9/16 po) d’épaisseur.
Attention
Avant d’eectuer les connexions, débranchez la borne de
masse de la batterie de voiture pour éviter tout court-circuit.
Veillez à utiliser des haut-parleurs de puissance adéquate. Si
vous utilisez des haut-parleurs de faible capacité, ils risquent
d’être endommagés.
Ne raccordez pas la borne du système de haut-parleurs à
la carrosserie de la voiture ou la borne du haut-parleur
droit avec celle du haut-parleur gauche.
Éloignez les câbles d’entrée et de sortie du câble
d’alimentation pour éviter les interférences.
Cet appareil est un amplificateur de haute puissance. Il ne
peut donc déployer sa pleine puissance que si les câbles de
haut-parleurs de la voiture lui sont raccordés.
Si votre voiture est équipée d’un système de navigation ou
d’un ordinateur de bord, ne retirez pas le l de terre de la
batterie de la voiture, sinon les données mémorisées seront
eacées. Si vous débranchez ce l, toute la mémoire de
l’ordinateur risque d’être eacée. Pour éviter un court-circuit
lorsque vous effectuez les branchements, branchez le câble
d’alimentation +12V après avoir branché tous les autres ls.
Make the terminal connections as illustrated below.
Procédez aux connexions des bornes comme illustré ci-dessous.
