On some audio-units, when the instru-
ment panel lights are on, the letters on op-
erable buttons of the mode in current use
light up together with the mode selection
and eject buttons.
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, and 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 prob-
lems that probably do not indicate a prob-
lem with your radio:
FM
Fading and drifing stationsÐGenerally,
the effective range of FM is about 40 km
(25 miles). Once outside this range, you
may notice fading and drifting, which in-
crease with the distance from the radio
transmitter. They are often accompanied
by distortion. Multi-pathÐFM signals are reflective,
making it possible for two signals to reach
your antenna at the same time. If this hap-
pens, the signals will cancel each other
out,
causing a momentary flutter or loss of
reception.
Static and flutteringÐThese occur when
signals are blocked by buildings, trees, or
other large objects. Increasing the bass
level may reduce static and fluttering.
Station swappingÐIf the FM signal you
are listening to is interrupted or weak-
ened, 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.
AM
FadingÐAM 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 interferenceÐwhen 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.
StaticÐAM is easily affected by external
sources of electrical noise, such as high
tension power lines, lightening, or electri-
cal motors. This results in static.
CARING FOR YOUR CASSETTE PLAY-
ER AND TAPES
For high performance from your cassette
player and tapes:
Clean the tape head and other parts regu-
larly.
 A dirty tape head or tape path can de-
crease sound quality and tangle your
cassette tapes. The easiest way to
clean them is by using a cleaning tape.
(A wet tape is recommended.)
Use high-quality cassettes.
 Low-quality cassette tapes can cause
many problems, including poor sound,
inconsistent playing speed, and
constant auto-reversing. They can
also get stuck or tangled in the cas-
sette player.
