Preset buttons you want to
store in, for more than
two seconds. When the station
is stored, the Preset button
number and station frequency
appear on the display window.Radio Reception
Usually, a problem with radio
reception does not mean there is a
problem with your radio. It is just the
normal result of conditions outside
the vehicle. For example, nearby
buildings and terrain can interfere
with FM reception. Power lines or
telephone wires can interfere with
AM signals.
And of course, radio signals have a
limited range. The farther you are
from a station, the weaker its signal
will be. In addition, reception
conditions change constantly as
your vehicle moves.
Here are some common reception
problems that probably do not
indicate a problem with your radio.
FM Transmissions
Fading and drifting stations -
Generally, the effective range of FM
is about 40 km (25 miles). Once
outside this range, you may notice
fading and drifting, which increase
with the distance from the radio
transmitter. They are often
accompanied by distortion.
Multi-path - FM signals are
reflective, making it possible for two
signals to reach your antenna at the
same time. If this happens, the
signals will cancel each other out,
causing a momentary flutter or loss
of reception.
Static and fluttering - These occur
when signals are blocked by
buildings, trees, or other large
objects. Increasing the bass level
may reduce static and fluttering.
Station swapping - If the FM signal
you are listening to is interrupted or
weakened, and there is another
strong station nearby on the FM
band, your radio may tune in the
second station until the original
signal can be picked up again.
