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.

To prevent battery rise

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.

Protection function

There is a Protection function installed in the unit 
to protect the unit and speakers from various 
problems. When Protection operates, the indicator 
informs you of the condition. (Refer to page 5)
