Safety precautions
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
2
(AWG18) 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.
Make sure not to get your fingers caught
between the faceplate and the unit.
Be careful not to drop the unit or subject it
to strong shock.
The unit may break or crack because it
contains glass parts.
2WARNING
To prevent damage to the machine,
take the following precautions:
Make sure to ground the unit to a negative
12V 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 a short circuit when replacing a
fuse, first disconnect the wiring harness.
Do not place any object between the
faceplate and the unit.
Do not use your own screws. Use only the
screws provided. If you use the wrong
screws, you could damage the unit.
Do not apply excessive force to the open
faceplate or place objects on it. Doing so
will cause damage or breakdown.
