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
6-18
Station 2
88.3 MHz
qOperating 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
l
system.
Do not insert any objects, other than
l
CDs, into the slot.
