Safety precautions
I.a.WARNING
I
To prevent
injury
or fire, take the following precautions:
• Mounting and wiring this product requires
skills
and experience. For
safety's sake, leave the mounting and wiring work to professionals.
• To prevent a short circuit, never put or leave any metallic objects
(such
as
coins or metal tools) inside the unit
• If the unit starts to emit smoke or
strange
smells, turn off the power
immediately and consult your KENWOOD dealer .
• Do not touch the unit during use because the surface of the unit becomes
hot and may cause burns if touched.
I
.a.CAUTION
I
To prevent damage to the machine, take the following precautions:
• Be sure the unit is connected to a 12 V DC power supply with a negative
ground connection.
• Do not open the top or bottom covers of the unit
• Do not install the unit in a spot exposed to direct sunlight or excessive
heat or humidity.
• When replacing a fuse, only use a new one with the prescribed rating. Using
a fuse with the wrong rating may cause your unit to malfunction.
• To prevent a short circuit when replacing a fuse, first disconnect the
wiring harness.
I
NOTE!
• If you experience problems during installation, consult your KENWOOD
dealer.
• If the unit does not seem to be working right, consult your KENWOOD
dealer.
CINning the unit
If the front panel gets dirty, turn off the power and wipe the panel with a
dry
silicon
cloth or soft cloth.
I
.a.
CAUTIO}il
Do not wipe the panel with a hard cloth or a cloth dampened by volatile
solvents such as paint thinner and alcohol. They can scratch the surface of the
panel and/ or cause the indicator letters to peel off.
To
prevent battery
rise
When the unit is used in the ACC ON position without turning the engine
ON, it depletes the battery. Use it after starting the engine.
Protection
function
The protection function is activated in the following situations:
This unit is equipped with a protection function for protecting this unit and
your speakers from various accidents or problems that can occur.
When the protection function is triggered, the amplifier stops operating.
• When a speaker wire may be short-circuited.
• When a speaker output contacts ground.
• When the unit malfunctions and a DC signal is sent to the speaker output
• When the internal temperature is high and unit won't operate.
• When detects a low impedance at the speaker connections.
Wiring
• If a buzzing noise is heard from the speakers when the engine is running,
connect a line noise filter (optional) to each of the battery wire.
• Do not allow the wire to directly contact the edge of the iron plate by
using Grommets.
• Connect the ground wire to a metal part of the car chassis that acts as an
electrical ground passing electricity to the battery's negative0terminal.
Do not turn the power on if the ground wire is not connected.
• Be sure to install a protective fuse in the power cord near the battery. The
protective fuse should be the same capacity as the unit's fuse capacity or
somewhat larger.
• When more than one power amplifier are going to be used, use a power
supply wiring wire and protective fuse of greater current-handling capac-
ity than the total maximum current drawn by each amplifier.
Speaker selection
• Using speakers with
smaller
input ratings than the amplifier's output
power would result in
smoke
generation or equipment failure.
• The impedance of the speakers that are going to be
connected
should
be 2 0 or greater (for stereo connections), or 4 0 or greater
(for
bridged
connections). When more than one set of speakers are going to be used,
calculate the
combined
impedance of the speakers and then connect
suitable speakers to the amplifier.

I
A
ATTENTION
I
Pour niter tout dommage
d
l'appareil, veui/lez prendre Jes precau-
tions suivantes:
• Bien verifier que l'appareil est raccorde
a
une source d'alimentation CC de
12 V avec raccordement de masse negative.
• N' o uvrez pas le couverde superieur ou inferieur de l'appareil.
• N1nstallez pas l'appareil dans un endroit expose directement
a
la lumiere
du soleil,
a
une chaleur excessive ou
a
l'humidite.
• Lors du remplacement d'un fusible, utilisez seulement un fusible neuf
avec la valeur indi9uee. !:utilisation d'un fusible d'une valeur differente
peut etre la caused un mauvais fonctionnement de votre appareil.
• Pour eviter les courts-circuits lors du remplacement d'un fusible, decon-
nectez d'abord le faisceau de cables.
I
REMARQUE
I
• Si vous rencontrez des problemes pendant 11nstallation, consultez votre
revendeur KENWOOD.
• Si l'appareil semble ne pas fonctionner correctement, consultez votre
revendeur KENWOOD.
Nettoyage
de l'apparell
Si la surface de l'appareil sale, l'essu~er avec un chiffon au
silicone
ou un
chiffon doux et sec a pres avoir eteint I appareil.
I
A

a
peinture ou de l'alcool. II pourrait rayer la sur-
face du panneau et/ ou ecailler les lenres d1nformations.
Comment
niter
une "'1ratlon de la batterie
Lorsque l'unite est utilisee avec I' ACC sur ON, sans que le moteur ne soit
