Operating Tips for CD Player/In-
Dash CD Changer
Condensation phenomenon
Immediately after turning on the heater
when the vehicle is cold, the CD or
optical components (prism and lens) in the
CD player/In-dash CD changer may
become clouded with condensation. At
this time, the CD will eject immediately
when placed in the unit. A clouded CD
can be corrected simply by wiping it with
a soft cloth. Clouded optical components
will clear naturally in about an hour. Wait
for normal operation to return before
attempting to use the unit.
Handling the CD player/In-dash CD
changer
The following precautions should be
observed.
Do not spill any liquid on the audio
system.
Do not insert any objects, other than
CDs, into the slot.

The CD revolves at high speed within
the unit. Defective (cracked or badly
bent) CDs should never be used.
Do not use non-conventional discs
such as heart-shaped, octagonal discs,
etc. The disc may not eject resulting in
a malfunction.
If the memory portion of the CD is
transparent or translucent, do not use
the disc.
