Interior Features
Audio System
Signals from an FM transmitter are similar
to beams of light because they do not
bend around corners, but they do refl ect.
Unlike AM signals, FM signals cannot
travel beyond the horizon. Therefore, FM
stations cannot be received at the great
distances possible with AM reception.
AM wave FM wave
FM wave
100—200 km (60—120 miles) Ionosphere
Atmospheric conditions can also affect
FM reception. High humidity will cause
poor reception. However, cloudy days may
provide better reception than clear days.
Multipath noise
Since FM signals can be refl ected by
obstructions, it is possible to receive both
the direct signal and the refl ected signal
at the same time. This causes a slight
delay in reception and may be heard as a
broken sound or a distortion. This problem
may also be encountered when in close
proximity to the transmitter.
Reflected wave
Direct
Flutter/Skip noise
Signals from an FM transmitter move in
straight lines and become weak in valleys
between tall buildings, mountains, and
other obstacles. When a vehicle passes
through such an area, the reception
conditions may change suddenly, resulting
in annoying noise.
Weak signal noise
In suburban areas, broadcast signals
become weak because of distance from the
transmitter. Reception in such fringe areas
is characterised by sound breakup.

Strong signal noise
This occurs very close to a transmitter
tower. The broadcast signals are extremely
strong, so the result is noise and sound
breakup at the radio receiver.
Station drift noise
When a vehicle reaches the area of two
strong stations broadcasting at similar
frequencies, the original station may be
temporarily lost and the second station
picked up. At this time there will be some
noise from this disturbance.

Operating Tips for CD Player
Condensation phenomenon
Immediately after turning on the heater
when the vehicle is cold, the CD or
optical components (prism and lens) in
the CD player may become clouded with
condensation. At this time, the CD will
eject immediately when placed in the unit.
A clouded CD can be corrected simply by
wiping it with a soft cloth. Clouded optical
components will clear naturally in about
an hour. Wait for normal operation to
return before attempting to use the unit.
Handling the CD player
The following precautions should be
observed.
 


 Do not use deformed or cracked CDs.
The disc may not eject resulting in a
malfunction.
 


 Do not use non-conventional discs such
as heart-shaped, octagonal discs, etc.
The disc may not eject resulting in a
malfunction.

 If the memory portion of the CD is
transparent or translucent, do not use the
disc.

 A new CD may have rough edges on its
inner and outer perimeters. If a disc with
rough edges is used, proper setting will
not be possible and the CD player will
not play the CD. In addition, the disc
may not eject resulting in a malfunction.
Remove the rough edges in advance
by using a ball-point pen or pencil as
shown below. To remove the rough
edges, rub the side of the pen or pencil
against the inner and outer perimeter of
the CD.
 


 When driving over uneven surfaces, the
sound may jump.
 


 CDs bearing the logo shown in the
illustration can be played. No other discs
can be played.
 


 Use discs that have been legitimately
produced. If illegally-copied discs such
as pirated discs are used, the system may
not operate properly.
 


 Be sure never to touch the signal surface
when handling the CDs. Pick up a CD
by grasping the outer edge or the edge of
the hole and the outer edge.
 


 Do not stick paper or tape on the CD.
Avoid scratching the reverse side (the
side without a label). The disc may not
eject resulting in a malfunction.
 


 Dust, fi nger smudges, and dirt can
decrease the amount of light refl ected
from the signal surface, thus affecting
sound quality. If the CD should become
soiled, gently wipe it with a soft cloth
from the centre of the CD to the edge.
 


 Do not use record sprays, antistatic
agents, or household spray cleaners.
Volatile chemicals such as benzine and
thinner can also damage the surface of
the CD and must not be used. Anything
that can damage, warp, or fog plastic
should never be used to clean CDs.

 The CD player ejects the CD if the CD
is inserted upside down. Also dirty and/
or defective CDs may be ejected.
 


 Do not insert cleaning discs in the CD
player.
 


 Do not insert any disc with a peel-off
seal affi xed to it.




 This unit may not be able to play certain
CD-R/CD-RWs made using a computer
or music CD recorder due to disc
characteristics, scratches, smudges, dirt,
etc., or due to dust or condensation on
the lens inside the unit.
 


 Storing CDs in the vehicle exposed to
direct sunlight or high temperature may
damage the CD-R/CD-RWs, and make
them unplayable.
 


 CD-R/CD-RW exceeding 700 MB
cannot be played.
 


 This unit may not be able to play certain
discs made using a computer due to the
application (writing software) setting
used. (For details, consult the store
where the application was purchased.)
 


 It is possible that certain text data, such
as titles, recorded on a CD-R/CD-RW
may not be displayed when musical data
(CD-DA) is playing.
 


 The period from when a CD-RW is
inserted to when it begins playing is
longer than a normal CD or CD-R.
 


 Completely read the instruction manual
and cautions for CD-R/CD-RWs.
 


 Do not use discs with cellophane tape
adhering, partially peeled off labels,
or adhesive material exuding from the
edges of the CD label. Also, do not use
discs with a commercially-available
CD-R label affi xed. The disc may not
eject resulting in a malfunction.
Operating Tips for MP3
This unit plays fi les with the extension
(.mp3) as MP3 fi les.
CAUTION

Do not use an audio fi le extension on
fi les other than audio fi les. In addition,
do not change the audio fi le extension.
Otherwise, the unit will not recognise
the fi le correctly resulting in noise or a
malfunction.

Glossary
DVD-Video
DVD-Video is a video image storing
standard determined by the DVD forum.
“MPEG2”, a global standard in digital
compression technologies, has been
adopted which compresses on average
about 1/40th of the image data and stores
it. In addition, a variable-rate coding
technology, which changes the assigned
information amount according to the shape
of the screen image, has been adopted.
Audio information can be stored using
Dolby digital instead of PCM (Pulse Code
Modulation) and more realistic sounding
audio can be enjoyed.
In addition, various, supplementary
functions such as multi-language
availability are provided for enhanced
enjoyment.
DVD-VR
DVD-VR is short for DVD Video
Recording Format; video image storing
standard determined by the DVD forum.
Multi-angle
One of the DVD player's functions.
Because scenes can be recorded in
multiple angles (camera position), users
can choose a desired angle.
