Audio System 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 problems that probably do not indicate a problem with your radio: 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 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. 104 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. AM Fading - AM broadcasts are reflected by the upper atmosphere - 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. 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 broadcast. 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.

Audio System
104
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 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 in-
crease 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 hap-
pens, 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.
AM
Fading
– AM broadcasts are reflected by
the upper atmosphere – especially at night.
These reflected signals can interfere with
those received directly from the radio sta-
tion, causing the radio station to sound al-
ternately strong and weak.
Station interference
– When a reflected
signal and a signal received directly from a
radio station are very nearly the same fre-
quency, they can interfere with each other,
making it difficult to hear the broadcast.
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.
Caring for your cassette player 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 type 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 cassette play-
er.
Do not use a cassette if it has been
damaged or tangled or if its label is
peeling off.
Do not leave a cassette in the player if
you are not listening to it, especially if it
is hot outside.
Store cassettes in their cases and out of
direct sunlight.
Avoid using cassettes with a total play-
ing time longer than 100 minutes (50
minutes per side).
The tape used in
these cassette is thin and could get
stuck or tangled in the cassette player.
