FEATURES OF YOUR HYUNDAI
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.

STEREO SOUND SYSTEM
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 high quality reproduction. How-
ever, in some cases the signal 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 obstructions in the area.
