Safety precautions

2 WARNING

To prevent injury or fire, take the following

precautions:

· When extending the ignition, battery, or ground

wires, make sure to use automotive-grade wires

or other wires with a 5 mm² (AWG 10) or more to

prevent wire deterioration and damage to the wire

coating.

· To prevent a short circuit, never put or leave any

metallic objects (such as coins or metal tools) inside

the unit.

· If the unit starts to emit smoke or strange smells,

turn off the power immediately and consult your

Kenwood dealer.

· Do not touch the unit during use because the

surface of the unit becomes hot and may cause

burns if touched.

2 CAUTION

To prevent damage to the machine, take the

following precautions:

· Be sure the unit is connected to a 12V DC power

supply with a negative ground connection.

· Do not open the top or bottom covers of the unit.

· Do not install the unit in a spot exposed to direct

sunlight or excessive heat or humidity. Also avoid

places with too much dust or the possibility of water

splashing.

· When replacing a fuse, only use a new one with the

prescribed rating. Using a fuse with the wrong rating

may cause your unit to malfunction.

· To prevent a short circuit when replacing a fuse, first

disconnect the wiring harness.

NOTE

· If you experience problems during installation,

consult your Kenwood dealer.

· If the unit does not seem to be working right,

consult your Kenwood dealer.

Cleaning the unit

If the front panel gets dirty, turn off the power and

wipe the panel with a dry silicon cloth or soft cloth.

2 CAUTION

Do not wipe the panel with a hard cloth or a cloth

dampened by volatile solvents such as paint thinner

and alcohol. They can scratch the surface of the panel

and/or cause the indicator letters to peel off.

When the unit is used in the ACC ON position without

turning the engine ON, it depletes the battery. Use it

after starting the engine.
