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. 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. 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. CARING FOR YOUR COMPACT DISC PLAYER AND DISCS D Your compact disc player is intended for use with 12 cm (4.7 in.) discs only. D Extremely high temperatures can keep your compact disc player from working. On hot days, use the air conditioning to cool the vehicle interior before you listen to a disc. D Bumpy roads or other vibrations may make your compact disc player skip. D If moisture gets into your compact disc player, you may not hear any sound even though your compact disc player appears to be working. Remove the disc from the player and wait until it dries. CAUTION Compact disc players use an invisible laser beam which could cause hazardous radiation exposure if directed outside the unit. Be sure to operate the player correctly. 126

AUDIO SYSTEM
126
For example, nearby buildings and terrain
can interfere with FM reception.
Power lines
or telephone wires can interfere with AM sig-
nals.
And of course, radio signals have a lim-
ited range.
The farther you are from a station,
the weaker its signal will be.
In addition, re-
ception 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 no-
tice fading and drifting, which increase with
the distance from the radio transmitter.
They
are often accompanied by distortion.
Multi-path — FM signals are reflective, mak-
ing it possible for two signals to reach your an-
tenna 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 sig-
nals 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 station,
causing the radio station to sound alternately
strong and weak.
Station interference — When a reflected sig-
nal 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 ten-
sion power lines, lightening, or electrical mo-
tors.
This results in static.
CARING FOR YOUR COMPACT DISC
PLAYER AND DISCS
D
Your compact disc player is intended for
use with 12 cm (4.7 in.) discs only.
D
Extremely high temperatures can keep
your compact disc player from working.
On hot days, use the air conditioning to
cool the vehicle interior before you listen
to a disc.
D
Bumpy roads or other vibrations may
make your compact disc player skip.
D
If moisture gets into your compact disc
player, you may not hear any sound even
though your compact disc player appears
to be working.
Remove the disc from the
player and wait until it dries.
CAUTION
Compact disc players use an invisible
laser beam which could cause hazard-
ous radiation exposure if directed out-
side the unit.
Be sure to operate the
player correctly.
