Audio system
FM radio station
FM broadcasts are transmitted at high
frequencies and do not bend to follow
the earth's surface. Because of this, FM
broadcasts generally begin to fade at
short distances from the station. Also,
FM signals are easily affected by build‐
ings, mountains, or other obstructions.
These can result in certain listening
conditions which might lead you to be‐
lieve a problem exists with your radio.
The following conditions are normal and
do not indicate radio trouble:
5-04
• Fading - As your vehicle moves away
from the radio station, the signal will
weaken and sound will begin to fade.
When this occurs, we suggest that
you select another stronger station.
• Flutter/Static - Weak FM signals or
large obstructions between
transmitter and your radio can dis‐
turb the signal causing static or flut‐
tering noises to occur. Reducing the
treble level may lessen this effect un‐
til the disturbance clears.
• Station Swapping - As a FM signal
weakens, another more powerful sig‐
nal near the same frequency may be‐
gin to play. This is because your radio
is designed to lock onto the clearest
signal. If this occurs, select another
station with a stronger signal.
the
• Multi-Path Cancellation - Radio sig‐
nals being received from several di‐
rections can cause distortion or flut‐
tering. This can be caused by a direct
and reflected signal from the same
station, or by signals from two sta‐
tions with close frequencies. If this
occurs, select another station until
the condition has passed.
