Cleaning the unit
• If the faceplate of this unit is stained, wipe it
with a dry soft cloth such as a silicon cloth. If
the faceplate is stained badly, wipe the stain
off with a cloth moistened with neutral cleaner,
then wipe it again with a clean soft dry cloth.
NOTE
• Applying spray cleaner directly to the unit may
affect its mechanical parts. Wiping the faceplate
with a hard cloth or using a volatile liquid such
as thinner or alcohol may scratch the surface or
erase screened print.

Lens fogging
When you turn on the car heater in cold
weather, dew or condensation may form on
the lens in the disc player of the unit. Called
lens fogging, this condensation on the lens
may not allow discs to play. In such a situation,
remove the disc and wait for the condensation
to evaporate. If the unit still does not operate
normally after a while, consult your JVC dealer.

a ballpoint pen etc.
