Kia Cee'd: How Vehicle Audio Works / 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 buildings, mountains,
or other obstructions. These can
result in certain listening conditions
which might lead you to believe a
problem exists with your radio. The
following conditions are normal and
do not indicate radio trouble:

- 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 the
transmitter and your radio can disturb
the signal causing static or
fluttering noises to occur. Reducing
the treble level may lessen this
effect until the disturbance clears.

- Station Swapping - As a FM signal
weakens, another more powerful
signal near the same frequency
may begin 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.
- Multi-Path Cancellation - Radio
signals being received from several
directions can cause distortion
or fluttering. This can be caused by
a direct and reflected 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.
AM broadcasts can be received at
greater distances than FM broadcasts.
This is because AM radio
waves are transmitted at low frequencies.
These long, low frequency
radio waves can follow t ...
