Operation Manual

AM and FM radio signals are broad-
cast from transmitter towers located
around your city. They are intercepted
by the radio antenna on your vehicle.
This signal is then received by the radio
and sent to your vehicle speakers.
When a strong radio signal has
reached your vehicle, the precise engi-
neering of your audio system ensures
the best possible quality reproduction.
However, 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, close-
ness of other strong radio stations or
the presence of buildings, bridges or
other large obstructions in the area.
AM broadcasts can be received at
greater distances than FM broad-
casts.This is because AM radio waves
are transmitted at low frequencies.
These long, low frequency radio
waves can follow the curvature of the
earth rather than travelling straight out
into the atmosphere. In addition, they
curve around obstructions so that they
can provide better signal coverage.
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 eas-
ily 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:
