To prevent injury and/or fire, take the
following precautions:
• When extending the battery or ground
cables, make sure to use automotive-grade
cables or other cables with an area of 3 mm
2
(AWG12) or more to prevent cable
deterioration and damage to the cable
coating.
• To prevent short circuits, never put or leave
any metallic objects (e.g., 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.
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 short circuits when replacing a
fuse, first disconnect the wiring harness.
• 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

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.
