WARNINGS

3 mm

• 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.
• The driver must not put on the headphones while driving. It is dangerous to shut off the outside sounds while driving.
• If you need to operate the unit while driving, be sure to look around carefully.
• 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.
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 a 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  setting to prevent the speakers from being damaged (see page
24 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.
• The heat sink becomes very hot. Do not place any cable where it may touch the heat sink.
• Gather the cables up using the supplied cable tie as illustrated (only for KD-AVX77).
