CAUTION
• P IONEER does not recommend that you install or service your
display unit yourself. Installing or servicing the product may
expose you to risk of electric shock or other hazards.
R efer all installation and servicing of your display unit to authorized
Pioneer service personnel.
• S ecure all wiring with cable clamps or electrical tape. Do not allow
any bare wiring to remain exposed.
• D o not drill a hole into the engine compartment to connect the
yellow cable of the display unit to the vehicle battery. Engine
vibration may eventually cause the insulation to fail at the point
where the wire passes from the passenger compartment into the
engine compartment. Take extra care in securing the wire at this
point.
• I t is extremely dangerous to allow the microphone lead to become
wound around the steering column or gearstick. Be sure to install
the unit in such a way that it will not obstruct driving.
• M ake sure that cables will not interfere with moving parts of
the vehicle, such as the gearshift, parking brake or seat sliding
mechanism.
• D o not shorten any cables. If you do, the protection circuit may fail
to work properly.
WARNING
• U se speakers over 50 W (output value) and between 4 Ω to 8 Ω
(impedance value). Do not use 1 Ω to 3 Ω speakers for this unit.
• T he black cable is ground. When installing this unit or power amp
(sold separately), make sure to connect 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

• U se this unit with a 12-volt battery and negative grounding
only. Failure to do so may result in a fire or malfunction.
• T o prevent a short-circuit, overheating or malfunction, be
sure to follow the directions below.
— Disconnect the negative terminal of the battery before
installation.
— Secure the wiring with cable clamps or adhesive tape.
Wrap adhesive tape around wiring that comes into contact
with metal parts to protect the wiring.
— Place all cables away from moving parts, such as the
gear shift and seat rails.
— Place all cables away from hot places, such as near the
heater outlet.
— Do not connect the yellow cable to the battery by passing
it through the hole to the engine compartment.
— Cover any disconnected cable connectors with insulating
tape.
— Do not shorten any cables.
— Never cut the insulation of the power cable of this unit
in order to share the power with other devices. The
current capacity of the cable is limited.
— Use a fuse of the rating prescribed.
— Never wire the negative speaker cable directly to ground.
— Never band together negative cables of multiple speakers.
• W hen this unit is on, control signals are sent through the
blue/white cable. Connect this cable to the system remote
control of an external power amp or the vehicle's auto-
antenna relay control terminal (max. 300 mA 12 V DC).
If the vehicle is equipped with a glass antenna, connect it to
the antenna booster power supply terminal.
• N ever connect the blue/white cable to the power terminal of
an external power amp.
Also, never connect it to the power terminal of the
auto antenna. Doing so may result in battery drain or a
malfunction.
