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. 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 Transmissions
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.

90 Infotainment System
AM Transmissions
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,
lightning, or electrical motors. This
results in static.

Using the Compact Disc
System
Disc
When it is cold or when it is raining,
the car windows will fog up and
cause condensation (water drops) to
form in the vehicle compartment.
When this happens, the audio may
skip, and playback will stop.
Ventilate the vehicle compartment
and dehumidify before
resuming use.
The audio may skip due to violent
vibrations when the car is traveling
across harsh roads. Never insert foreign objects into the
disc insertion slot.
Do not insert a wet disc into the
player.
This player uses an invisible laser
beam which could cause hazardous
radiation exposure if directed
outside the player. Be sure to
operate the player correctly.
Playback may not be possible due
to recording conditions or disc
characteristics, scratches, dirt,
or deterioration.
Usable Discs
Music CDs with the following marks
can be used. CD-R and CD-RW
discs recorded according to the
CD-DA format can also be played.
.
CD-R (CD-Recordable), CD-RW
(CD-ReWritable) may not be
able to play back due to the
recording condition,
characteristics of the disc,
damage, dirt or deterioration due
to long exposure to the
environment of the vehicle
compartment. CD-R, CD-RW

recording side or the label side as it
may lead the disc to malfunction. Do not use a disc with cracks or if it
is severely bent as it may lead to
damage.
Hold the disc without touching the
recording side as this may make the
disc dirty and lead to the audio
skipping.
Using benzene, record disc cleaner,
or anti-static fluids may damage the
disc. Using a dirty disc will damage
the disc and lead to audio skipping.
When the disc is dirty, use a
commercial disc cleaner to gently
clean it from the inside to the
outside. Do not use lens cleaner.
Do not use the types of disc
described below because such
discs may cause a breakdown.
.

Media
Media such as CD-R and CD-RW

environments and part of the CD-R
and CD-RW may become incapable of playback. Fingerprints or
scratches on the disc may prevent
playback or cause skipping during
playback. Sections of a CD-R or
CD-RW may deteriorate if it is left
inside a vehicle for long periods of
time. It is also recommended that
CD-R and CD-RW discs be kept in
a light-resistant case because the
discs are vulnerable to ultra-violet
light.
