Operating information
CAUTION
.
To avoid damage to the audio/
visual system:
–
Be careful not to spill bev-
erages over the audio/visual
system.
–
Do not put anything other than
an appropriate disc into the
disc slot.
NOTE
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.
!
Radio
Usually, a problem with radio reception
does not mean there is a problem with the
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 phone wires can interfere with AM
signals. And of course, radio signals have
a limited range. The farther the vehicle is
from a station, the weaker its signal will
be. In addition, reception conditions
change constantly as the vehicle moves.
Here, some common reception problems
that probably do not indicate a problem
with the radio are described.
!
FM
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 transmit-
ter. They are often accompanied by
distortion.
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 fluttering.
Station swapping: If the FM signal being
listened to is interrupted 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 atmosphere
—
especially at
night. These reflected signals can inter-
fere with those received directly from the
radio station, causing the radio station to
sound alternately strong and weak.
Station interference: When a reflected
signal and a signal received directly from
a radio station are very nearly the same
frequency, they can interfere with each
other, making it difficult to hear the broad-
cast.
Static: AM is easily affected by external
sources of electrical noise, such as high
tension power lines, lightening or electrical
motors. This results in static.
