863-6. Tips for operating the audio/visual system
3-6.Tips for operating the audio/visual system
●The use of a cellular phone inside
or near the vehicle may cause a
noise from the speakers of the
audio/visual system which you are
listening to. However, this does
not indicate a malfunction.
Usually, a problem with radio
reception does not mean there
is a problem with the radio  it
is just the normal result of condi-
tions outside the vehicle.
For example, nearby buildings
and terrain can interfere with FM
reception. Power lines or phone
wires can interfere with AM sig-
nals. And of course, radio sig-
nals have a limited range. The
farther the vehicle is from a sta-
tion, the weaker i ts signal will
be. In addition, reception condi-
tions change constantly as the
vehicle moves.
Here are some common recep-
tion problems that may not indi-
cate a problem with the radio as
described.
■FM
Fading and drifting stations:
Generally, the effective range of FM is about 25 miles (40 km).
Once outside this range, you
may notice fading and drifting,
which increase with the distance
from the radio transmitter. They
are often accompanied by dis-
tortion.
Multi-path: FM signals are
reflective, making it possible for
2 signals to reach the vehicle’s
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 flut-
tering.
Station swapping: If the FM sig-
nal being listened to is inter-
rupted or weakened, and there
is another strong station nearby
on the FM band, the radio may
tune in the second station until
the original signal can be picked
up again.
■AM
Fading: AM broadcasts are
reflected by the upper atmo-
sphere  especially at night.
These reflected signals can
interfere with those received
directly from the radio station,
causing the radio station to
sound alternately strong and
weak.

●To avoid damage to the
audio/visual system:
