Connecting the Units
WARNING
• Always use the special red battery and ground wire
[RD-223], which is sold separately. Connect the
battery wire directly to the car battery positive ter-
minal (+) and the ground wire to the car body.
• Do not touch the amplifier with wet hands.
Otherwise you may get an electric shock. Also, do
not touch the amplifier when it is wet.
• For traffic safety and to maintain safe driving
conditions, keep the volume low enough so that
you can still hear normal traffic sound.
• Check the connections of the power supply and
speakers if the fuse of the separately sold battery
wire or the amplifier fuse blows. Detect the cause
and solve the problem, then replace the fuse with
another one of the same size and rating.
• To prevent malfunction of the amplifier and speak-
ers, the protective circuit will cut the power supply
to the amplifier (sound will stop) when an abnor-
mal condition occurs. In such a case, switch the
power to the system OFF and check the
connection of the power supply and speakers.
Detect the cause and solve the problem.
• Contact the dealer if you cannot detect the cause.
• To prevent an electric shock or short-circuit
during connection and installation, be sure to
disconnect the negative (–) terminal of the battery
beforehand.
• Confirm that no parts are behind the panel when
drilling a hole for installation of the amplifier. Be
sure to protect all cables and important equipment
such as fuel lines, brake lines and the electrical
wiring from damage.
CAUTION
• When installing this unit, disconnect the negative
(–) terminal of the battery to avoid the risk of
short-circuit and damage to the unit.
• Secure the wiring with cable clamps or adhesive
tape. To protect the wiring, wrap adhesive tape
around it where they lie against metal parts.
• Do not route wires where they will get hot, for
example where the heater will blow over them. If
the insulation heats up, it may become damaged,
resulting in a short-circuit through the vehicle
body.
• Make sure that wires will not interfere with mov-
ing parts of the vehicle, such as the gearshift,
handbrake or seat sliding mechanism.
• Do not shorten any wires. Otherwise the protection
circuit may fail to work when it should.
• Never feed power to other equipment by cutting
the insulation of the power supply wire to tap from
the wire. The current capacity of the wire will be
exceeded, causing overheating.
