THIS PRODUCT YOURSELF. Installing
or servicing this product and its connect-
ing cables may expose you to the risk of
electric shock or other hazards, and can
cause damage to this product that is not
covered by warranty.
Connection
Precautions before connecting
the system
WARNING
Do not take any steps to tamper with or
disable the parking brake interlock sys-
tem which is in place for your protection.
Tampering with or disabling the parking
brake interlock system could result in
serious injury or death.
CAUTION
Secure all wiring with cable clamps
or electrical tape. Do not allow any
bare wiring to remain exposed.
Do not directly connect the yellow
lead of this product to the vehicle
battery. If the lead is directly con-
nected to the battery, engine vibra-
tion may eventually cause the insula-
tion to fail at the point where the wire
passes from the passenger compart-
ment into the engine compartment. If
the yellow lead’s insulation tears as
a result of contact with metal parts,
short-circuiting can occur, resulting
in considerable danger.
It is extremely dangerous to allow
cables to become wound around the
steering column or shift lever. Be
sure to install this product, its cables,
and wiring away in such so that they
will not obstruct or hinder driving.
Make sure that the cables and wires
will not interfere with or become
caught in any of the vehicle’s moving
parts, especially the steering wheel,
shift lever, parking brake, sliding seat
tracks, doors, or any of the vehicle’s
controls.
Do not route wires where they will
be exposed to high temperatures. If
the insulation heats up, wires may
become damaged, resulting in a short
circuit or malfunction and permanent
damage to the product.
Do not shorten any leads. If you do,
the protection circuit (fuse holder,
fuse resistor or filter, etc.) may fail to
work properly.
Never feed power to other electronic
products by cutting the insulation of
the power supply lead of this prod-
uct and tapping into the lead. The
current capacity of the lead will be
exceeded, causing overheating.
Before installing this product
Use this unit with a 12-volt battery and
negative grounding only. Failure to do so
may result in a fire or malfunction.
To avoid shorts in the electrical system,
be sure to disconnect the (–) battery
cable before installation.
To prevent damage
WARNING
Use speakers over 50 W (output
value) and between 4 W to 8 W
(impedance value). Do not use 1 W to
3 W speakers for this unit.
The black cable is ground. When
installing this unit or power amp
(sold separately), make sure to con-
nect the ground wire first. Ensure
that the ground wire is properly
connected to metal parts of the car’s
body. The ground wire of the power
amp and the one of this unit or any
other device must be connected to
the car separately with different
screws. If the screw for the ground
wire loosens or falls out, it could
result in fire generation of smoke or
malfunction.

When replacing the fuse, be sure
to only use a fuse of the rating pre-
scribed on this product.
This product cannot be installed in a
vehicle without ACC (accessory) position
on the ignition switch.

To avoid short-circuiting, cover the
disconnected lead with insulating tape.
It is especially important to insulate all
unused speaker leads, which if left uncov-
ered may cause a short circuit.
For connecting a power amp or other
devices to this product, refer to the man-
ual for the product to be connected.
■ Notice for the blue/white lead
When the ignition switch is turned on
(ACC ON), a control signal is output
through the blue/white lead. Connect to
an external power amp’s system remote
control terminal, the auto-antenna relay
control terminal, or the antenna booster
power control terminal (max. 300 mA
12 V DC). The control signal is output
through the blue/white lead, even if the
audio source is switched off.
