Available Control Units:
A KENWOOD’s LX-Bus supporting Center Unit released in 2004 or later can
control this unit. The operations of the (LX) AMP Control are explained in the
Operation Manual of the Center Unit.
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.

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.
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.
To prevent battery rise
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.
Protection function
There is a Protection function installed in the unit to protect the unit and
speakers from various problems. When Protection operates, the display informs
you of the condition.
