Before Installation

Before installation of this unit, please note the
following precautions.
# WARNINGS

the battery wire (yellow) to the car chassis
(ground), you may cause a short circuit, that
in turn may start a fire. Always connect those
wires to the power source running through
the fuse box.
• Do not cut out the fuse from the ignition wire
(red) and the battery wire (yellow). The power
supply must be connected to the wires via
the fuse.
# CAUTION
• Install this unit in the console of your vehicle.
Do not touch the metal part of this unit during
and shortly after the use of the unit. Metal part
such as the heat sink and enclosure become
hot.
NOTE
• Mounting and wiring this product requires
skills and experience. For best safety, leave the
mounting and wiring work to professionals.
• Do not install the unit if it becomes an obstacle
to driver performance.
• Adjust the panel position not to become an
obstacle to driver performance.
• Make sure to ground the unit to a negative 12V
DC power supply.
• Do not install the unit in a spot exposed to
direct sunlight or excessive heat or humidity.
Also avoid places with too much dust or the
possibility of water splashing.
• Do not use your own screws. Use only the
screws provided. If you use the wrong screws,
you could damage the unit.
• If the power is not turned ON ("There is an
error in the speaker wiring. Please check the
connections. " is displayed), the speaker wire
may have a short-circuit or touched the chassis
12
of the vehicle and the protection function may
have been activated. Therefore, the speaker
wire should be checked.
• If your car's ignition does not have an ACC
position, connect the ignition wires to a power
source that can be turned on and off with the
ignition key. If you connect the ignition wire to
a power source with a constant voltage supply,
such as with battery wires, the battery may be
drained.
• If the console has a lid, the lid will not be
closed even when the unit is installed correctly.
• If the fuse blows, first make sure the wires are
not touching to cause a short circuit, then
replace the old fuse with one with the same
rating.
• Insulate unconnected wires with vinyl tape or
other similar material. To prevent a short circuit,
do not remove the caps on the ends of the
unconnected wires or the terminals.
• Connect the speaker wires correctly to the
terminals to which they correspond. The unit
may be damaged or fail to work if you share
the ¤ wires or ground them to any metal part
in the car.
• When only two speakers are being connected
to the system, connect the connectors either
to both the front output terminals or to both
the rear output terminals (do not mix front
and rear). For example, if you connect the ¢
connector of the left speaker to a front output
terminal, do not connect the ¤ connector to
a rear output terminal.
• After the unit is installed, check whether the
brake lamps, blinkers, wipers, etc. on the car
are working properly.
• Mount the unit so that the mounting angle is
30° or less.
• This unit has the cooling fan to decrease the
internal temperature. Do not mount the unit
in a place where the cooling fan of the unit is
blocked. Blocking these openings will inhibit
the cooling of the internal temperature and
result in malfunction.
