Safety precautions

2WARNING
To prevent injury or fire, take the
following precautions:
• Insert the unit all the way in until it is fully
locked in place. Otherwise it may fall out of
place when jolted.
• When extending the ignition, battery, or ground
wires, make sure to use automotive-grade
wires or other wires with a 0.75mm
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.

To prevent damage to the machine, take
the following precautions:
• Make sure to ground the unit to a negative 12
V DC power supply.
• 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.
• Do not subject the faceplate to excessive
shock, as it is a piece of precision equipment.
• 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.
• Do not use your own screws. Use only the
screws provided. If you use the wrong screws,
you could damage the unit.
