NOTE
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 use hard cloths or paint thinner,
alcohol, or other volatile solvents. These may
damage external surfaces or remove
indicator characters.
Lens fogging
In cold climates, there may be a period after
you turn on your vehicle’s heater when the
lens that guides the laser beam used in your
CD player fogs up. If this happens, you
cannot play compact discs. Take out discs
and the fogging will disappear. If it does not
return to normal after several hours, contact
your Kenwood dealer.
