car audio dealers.
WARNINGS
• DO NOT install any unit or wire any cable in a location where;
– it may obstruct the steering wheel and gearshift lever operations, as this may result in a traffic
accident.
– it may obstruct the operation of safety devices such as air bags, as this may result in a fatal
accident.
– it may obstruct visibility.
• DO NOT operate any unit while manipulating the steering wheel, as this may result in a traffic
accident.
• The driver must not watch the monitor while driving. It may lead to carelessness and cause an
accident.
• If you need to operate the unit while driving, be sure to look around carefully or you may be
involved in a traffic accident.
• If the parking brake is not engaged, "Parking Brake" appears on the monitor, and no playback
picture will be shown.
– This warning appears only when the parking brake lead is connected to the parking brake
system built in the car.
To prevent short circuits, we recommend that you disconnect the battery's negative terminal and
make all electrical connections before installing the unit.
• Be sure to ground this unit to the car's chassis again after installation.
• Be sure any cable is not caught on the car's chassis or under seats.
Notes on electrical connections:
• Replace the fuse with one of the specified rating. If the fuse blows frequently, consult your JVC
car audio dealer.
• It is recommended to connect speakers with maximum power of more than 50 W (both at the
rear and at the front, with an impedance of 4 Ω to 8 Ω).
If the maximum power is less than 50 W, change <Amplifier Gain> setting to prevent the
speakers from being damaged (see page 38 of the INSTRUCTIONS).
• To prevent short circuits, cover the terminals of the
UNUSED leads with insulating tape.
• The heat sink becomes very hot after use. Be careful
not to touch it when removing this unit.
• At the time of installation, be sure to fix all wires
(wires both from this unit and from the car itself) in a
way that any wires cannot come into contact with heat
sinks on the rear and side of the unit.
PRECAUTIONS on power supply and speaker connections:
• DO NOT connect the speaker leads of the power cord to the car battery; otherwise,
the unit will be seriously damaged.
• BEFORE connecting the speaker leads of
the power cord to the speakers, check the
speaker wiring in your car.
