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 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.

• Make sure to ground the unit to a negative
