Accessories/ Installation Procedure
¤
• 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, as
with battery wires, the battery may die.
• If the console has a lid, make sure to install the unit so that
the faceplate 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 - 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.
If You Want to Connect iPod

AUDIO OUT
KCA-iP200 (Optional accessory)
• No other optional accessory can be connected because
the USB connector and the AUX input are used for iPod
connection.
• Dual Zone System in <Audio Setup> (page 9) will become
unavailable.
