Knowing your vehicle
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 con-
ditions which might lead you to believe a
problem exists with your radio. The fol-
lowing conditions are normal and do not
indicate radio trouble:
• Fading - As your car 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 the trans-
mitter and your radio can disturb the
signal causing static or fluttering nois-
es to occur. Reducing the treble level
may lessen this effect until the distur-
bance clears.
• Station Swapping - As a FM signal
weakens, another more powerful sig-
nal near the same frequency may
begin to play. This is because your
radio is designed to lock onto the clear-
est signal. If this occurs, select anoth-
er station with a stronger signal.
• Multi-Path Cancellation - Radio signals
being received from several directions
can cause distortion or fluttering. This
can be caused by a direct and reflect-
ed signal from the same station, or by
signals from two stations with close
frequencies. If this occurs, select
another station until the condition has
passed.
