Interior Comfort
Audio System
Strong signal noise
This occurs very close to a transmitter
tower. The broadcast signals are
extremely strong, so the result is noise and
sound breakup at the radio receiver.
Station drift noise
When a vehicle reaches the area of two
strong stations broadcasting at similar
frequencies, the original station may be
temporarily lost and the second station
picked up. At this time there will be some
noise from this disturbance.
Station 1
88.1 MHz
6-14
Station 2
88.3 MHz
qOperating Tips for CD Player
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 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
The following precautions should be
observed.
Do not spill any liquid on the audio
l
system.
Do not insert any objects, other than
l
CDs, into the slot.
