Safety precautions
2 CAUTION
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.
• 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 use your own screws. Use only the screws
provided. If you use the wrong screws, you could
damage the unit.
2 WARNING
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 0.75mm² (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.
• Do not touch the liquid crystal fluid if the LCD
is damaged or broken due to shock. The liquid
crystal fluid may be dangerous to your health or
even fatal.
If the liquid crystal fluid from the LCD contacts
your body or clothing, wash it off with soap
immediately.
