INTRODUCTION
•Cleaning the unit:
1. Turn the cabin power “OFF”and wipe the panel with a dry, lint free,
silicon cloth.
Note: Use of rough cloth or volatile solvents such as paint thinner or
alcohol may damage the surface of the panel and/or cause damage
to the liquid crystal display.
2. The CD magazine in the remote changer should be cleaned periodically as
accumulated dust can scratch the surface of the CDs when inserted or
removed from the magazine.
3. In cold weather, condensation may form on the lenses inside the remote
changer when the unit is first turned on. This lens fogging may make it
impossible to play a CD. Remove the CD and wait for the unit to warm
and the condensation to evaporate.
