Before Installation

Before installation of this unit, please
note the following precautions.
WARNINGS
• If you connect the ignition wire (red)
and 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.
NOTES
• Mounting and wiring this product requires
skills and experience. For best safety, leave the
mounting and wiring work to professionals.
• 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 ("PROTECT" is
displayed), the speaker wire may have a short-
circuit or touched the chassis 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, make sure to install the
unit so that the front panel will not hit the lid
when closing and opening.
• If the fuse blows, first make sure the wires aren't
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
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 are
blocked. Blocking these openings will inhibit
the cooling of the internal temperature and
result in malfunction.
• Do not press hard on the panel surface when
installing the unit to the vehicle. Otherwise scars,
damage, or failure may result.
• Reception may drop if there are metal objects
near the Bluetooth antenna.
