Safety precautions
2WARNING
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.
•  Mounting and wiring this product requires skills and 
experience. For safety’s sake, leave the mounting and 
wiring work to professionals.
2CAUTION
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 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.
To prevent battery from running out
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.
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.
