Safety precautions
IA.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
I
• If you experience problems during installation, consult your KENWOOD
dealer.
• If the unit does not seem to be working right, consult your KENWOOD
dealer.
Cleaning the unit
If the front panel gets dirty, turn off the power and wipe the panel with a
dry silicon cloth or soft cloth.
IACAUTION
I
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 buuing 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
eviter
tout dommage
a
l'appareil, veuillez prendre /es 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.
• Ninstallez 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 indiquee. L'utilisation d'un fusible d'une valeur differente
peut
etre
la cause d'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'appareil
Si la
surface
de l'appareil sale, l'essuyer avec un chiffon au silicone ou un
chiffon doux et
sec
a pres avoir
eteint
l'appareil.
I
A ATTENTION

sur-
face du panneau et/ ou ecailler les
lettres
d1nformations.
Comment eviter une elevation de la batterle
Lorsque
l'unite
est utilisee avec
l'ACC
sur ON,
sans
que le moteur ne
soit
allume, cela decharge la batterie. II est preferable de l'utiliser apres avoir
allume le moteur.
