AUDIO/VIDEO SYSTEM

CD-R/CD-RW discs may be damaged
by direct exposure to sunlight, high
temperatures or other storage condi-
tions. The unit may be unable to play
some damaged discs.
If you insert a CD-RW disc into the
MP3/WMA player, playback will begin
more slowly than with a conventional
CD or CD-R disc.
Recordings on CD-R/CD-RW cannot
be played using the DDCD (Double
Density CD) system.
This is a general term that describes the
process of writing data on-demand to
CD-R, etc., in the same way that data is
written to floppy or hard discs.
This is a method of embedding track-
related information in an MP3 file. This
embedded information can include the
track title, the artist’s name, the album
title, the music genre, the year of pro-
duction, comments and other data. The
contents can be freely edited using soft-
ware with ID3 tag editing functions.
Although the tags are restricted to a
number of characters, the information
can be viewed when the track is played
back.
WMA files can contain a WMA tag
that is used in the same way as an ID3
tag. WMA tags carry information such
as track title and artist name.This is the international standard for the
formatting of CD-ROM folders and
files. For the ISO 9660 format, there
are 2 levels of regulations.
Level 1: The file name is in 8.3 format
(8 character file names, with a 3 charac-
ter file extension. File names must be
composed of one-byte capital letters
and numbers. The “_” symbol may also
be included.)
Level 2: The file name can have up to
31 characters (including the separation
mark “.” and file extension). Each
folder must contain fewer than 8 hierar-
chies.
Playlists created using “WINAMP”
software have a playlist file extension
(.m3u).
MP3 is an audio compression standard
determined by a working group
(MPEG) of the ISO (International Stan-
dard Organization). MP3 compresses
audio data to about 1/10 the size of that
on conventional discs.
WMA (Windows Media Audio) is an
audio compression format developed
by Microsoft
®. It compresses files into
a size smaller than that of MP3 files.
The decoding formats for WMA files
are Ver. 7, 8 and 9.

DETECTION RANGE OF THE
SENSORSSENSOR DETECTION
INFORMATION
Certain vehicle conditions and the
surrounding environment may affect
the ability of a sensor to correctly de-
tect an obstacle. Particular instances
where this may occur are listed be-
low.
In addition to the examples above,
there are instances in which, because
of their shapes, signs and other
objects may be judged by a sensor to
be closer than they are.
