Safetyprecautions
IACAUTION I
To prevent damage to the machine, take the
following precautions:
Be sure the unit is connected to a 12V DC power
supply
with anegative ground connection.
Do
not open the top or bottom covers of the unit.
Do
not install the unit in aspot exposed to direct
sunlight or excessive heat or humidity. Also avoid
places with
too much dust or the possibility of water
splashing.
When replacing a
fuse, only use anew one with the
prescribed rating. Using afuse with the wrong rating
may cause your unit
to malfunction.
•
To prevent ashort circuit when replacing a fuse, first
disconnect the wiring harness.
FCC WARNING
This equipment may generate or use radio
frequency energy. Changes or modifications
to this
equipment may cause harmful interference unless
the modifications are expressly approved in the
instruction manual. The user could lose the authority
to operate this equipment if an unauthorized change
or modification
is made.
FCC NOTE
This equipment has been tested and found to

as
household waste.
•Old electrical and electronic
equipment
••• should be recycled ct afacility capable
of handling these items and their waste
byproducts. Contact your local authority
for details in locating arecycle facility
nearest
to you. Proper recycling and waste
disposal will help conserve resources whilst
preventing detrimental effects on our
health and the
environment
This Product is not installed by the manufacturer of a
vehicle on the production line, nor by the professional
importer
of avehicle into an EU Member State.
Cleaning the unit
Ifthe front panel gets dirty, turn off the power and
wipe the panel with adry silicon cloth or soft cloth.
I ACAUTION I
Do not wipe the panel with ahard cloth or acloth
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
There is aProtection function installed in the unit to
protect the unit and speakers from various problems.
When Protection operates, the indicator informs you
of the condition. (Refer to page S)

•Wiring
• Take the battery wire for this unit directly from the
battery. If it's connected
to the vehicle's Wiring
harness, it
can cause blown fuses etc.
Ifabuzzing noise
is heard from the speakers when
the engine
is running, connect aline 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 ametal part of the car
chassis that acts as an electrical ground passing
electricity to the battery's negative 8terminal.
Do
not turn the power on ifthe ground wire is not
connected.
Be sure to install aprotective 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.
For the power cord and ground, use avehicle type
(fireproof) power wring cord
with acurrent capacity
greater than the unit's fuse capacity.
(Use apower
wiring cord with adiameter
of S mm' (AWG 10) or
greater.)
·When more than one power amplifier
are going
to be used,
use apower supply wiring wire and
protective fuse
of greater current-handling capacity
than the total maximum current drawn by each
amplifier.
•Speaker Selection
• The rated input power of the speakers that are
going to be connected should be greater than the
maximum
output power (in Watts) ofthe amplifier.
Use of speakers having input power ratings that
are less than the output power of the amplifier will
cause smoke to be emitted
as well as damage.
•The impedance
of the speakers that are going
to be connected should be 20 or greater (for
stereo connections), or
40 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.

·The genuine-accessory car stereo shall have a
maximum power
output of no more than 40 W.
·Do not connect the speaker output leads from
apower amplifier (Optional)
to the speaker
level
input terminals of this unit, for this may
cause malfunction or damage.
•Do not connect cables and leads
to both RCA
cable input jacks and the speaker level input
terminals simultaneously, for this may cause
malfunction or damage.
·Connect the power control lead to apower
supply which can be turned ON/OFF by
the ignition key switch
(ACC line). With this
connection, shock noise may
be generated
when the power
of the genuine-accessory car
stereo
is switched ON/OFF.

•Stereo Connections:
When you wish to use the unit as astereo
amplifier, stereo connections
are used.
The speakers to
be connected should have an
impedance of 20 or greater. When multiple
speakers are to be connected, ensure that the
combined impedance is 20 or greater for each
channel.
•Bridged Connections:
When you wish to use the unit as ahigh-
output monaural amplifier, bridged
connections
are used. (Make connections to
the
LEFT channel 0and the RIGHT channel 8
SPEAKER OUTPUT terminals.)
The speakers
to be connected should have an
impedance of 40 or greater. When multiple
speakers are to be connected, ensure that the
combined impedance is 40 or greater.

@Powerindicator
When the power is turned on, the Power indicator
lights.
Ifthe Power indicator does not light when the
power
is turned on, the protection function
may
be activated. Check whether there is any
indication
of trouble.
•The protection function is activated in
the following situations:
This unit is equipped with aprotection function
for protecting this unit and your speakers from
various accidents or problems that
can occur.
When the protection function
is triggered, the
Power indicator goes offand the amplifier stops
operating.
•When aspeaker wire may be short-circuited.
•When aspeaker
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 a
ground wire of the center unit
(cassette receiver, CD receiver, etc.) or this unit
is not connected to ametal part serving as
an electrical ground passing electricity to the
battery's negative eterminal.
