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.
