STEREO SOUND SYSTEM
FM broadcasts are transmitted at high fre-
quencies and do not bend to follow the earth's
surface. Because of this, FM broadcasts gen-
erally 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: AM broadcasts can be received at greater dis-
tances than FM broadcasts. This is because
AM radio waves are transmitted at low fre-
quencies. These long, low frequency radio
waves can follow the curvature of the earth
rather than travelling straight out into the atmo-
sphere. In addition, they curve around ob-
structions so that they can provide better
signal coverage.

How Car Audio Works
AM and FM radio signals are broadcast from
transmitter towers located around your city.
They are intercepted by the radio antenna on
your car. This signal is then received by the
radio and sent to your car speakers.
When a strong radio signal has reached your
vehicle, the precise engineering of your audio
system ensures the best possible quality re-
production. However, in some cases the sig-
nal coming to your vehicle may not be strong
and clear. This can be due to factors such as
the distance from the radio station, closeness
of other strong radio stations or the presence
of buildings, bridges or other large obstruc-
tions in the area.
