ENGLISH
This unit is designed to operate on 12 V DC, NEGATIVE ground electrical systems. If your
vehicle does not have this system, a voltage inverter is required, which can be purchased at JVC
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.
• Make sure no cable is 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  to 8 Ω).
• 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 no wires can come into contact with heat
sinks on the rear and side of the unit.
