Audio System
NOTE
  To prevent the battery from being
discharged, do not leave the audio
system on for a long period of time
when the engine is not running.
  If a cellular phone or CB radio is
used in or near the vehicle, it could
cause noise to occur from the audio
system, however, this does not
indicate that the system has been
damaged.
Do not spill any liquid on the audio
system.
Do not insert any objects, other than CDs,
into the slot.
Radio Reception
AM characteristics
AM signals bend around such things as
buildings or mountains and bounce off the
ionosphere.
Therefore, they can reach longer distances
than FM signals.
Because of this, two stations may
sometimes be picked up on the same
frequency at the same time.
Station 2 Station 1Ionosphere
FM characteristics
An FM broadcast range is usually about
40—50 km (25—30 miles) from the
source. Because of extra coding needed to
break the sound into two channels, stereo
FM has even less range than monaural
(non-stereo) FM.

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 reÀ 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 reÀ ected by
obstructions, it is possible to receive both
the direct signal and the reÀ 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.

Audio System
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

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.
Multi-language
As a function of the DVD player, audio
or subtitles for the same video images can
be stored in multiple languages and the
language can be selected freely. Region code
DVD players and discs are assigned codes
for each market region and only discs
manufactured for that speci¿ c region can
be played.
A disc cannot be played if the region code
assigned to the player is not indicated on
the disc.
In addition, even if a region code is not
indicated on the disc, disc playback may
be prohibited depending on the region. In
this case, a disc may not be playable in
this DVD player.
Operating Tips for OGG
OGG is the audio compression format for
Xiph. Org Foundation.
Audio data can be created and stored at a
higher compression ratio than MP3.
This unit plays ¿ les with the extension
(.ogg) as OGG ¿ les.
CAUTION
Do not use an audio ¿ le extension on
¿ les other than audio ¿ les. In addition,
do not change the audio ¿ le extension.
Otherwise, the unit will not recognise
the¿ le correctly resulting in noise or a
malfunction.
 


 OGG ¿ les written under speci¿ cations
other than the indicated speci¿ cation
may not play normally or ¿ les or folder
names may not display correctly.
 


 The ¿ le extension may not be provided
depending on the computer operating
system, version, software, or settings. In
this case, add the ¿ le extension “.ogg” to
the end of the ¿ le name, and then write
it to the disc/memory.
