AUDIO/VISUAL SYSTEM
MP3i (MP3 interactive) and MP3PRO
formats are not compatible with the audio
player.
 The player is compatible with VBR (Vari-
able Bit Rate).
 When playing back files recorded as VBR
(Variable Bit Rate) files, the play time will
not be correctly displa yed if the fast for-
ward or reverse op erations are used.
 It is not possible to check folders that do not
include MP3/WMA/AAC files.
 MP3/WMA/AAC files in folders up to 8
levels deep can be played. However, the
start of playback may be delayed when
using discs containing numerous levels of
folders. For this reason, we recommend
creating discs with no more than 2 levels of
folders. 
The play order of the compact disc with the
structure shown above is as follows:
 The order changes depending on the per-
sonal computer and MP3/WMA/AAC
encoding software you use.
001.mp3
002.wma
Folder 1
003.mp3Folder 2
004.mp3

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 number, track title, the artist’s name,
the album title, the music genre, the year of
production, comments, cover art and other
data. The contents can be freely edited
using software with ID3 tag editing func-
tions. 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 internationa l standard for the for-
matting 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 character 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 hierarchies. 
MP3 is an audio compression standard
determined by a working group (MPEG) of
the ISO (International Standard Organiza-
tion). 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 decod-
ing formats for WMA files are Ver. 7, 8 and
9.
 AAC is short for Advanced Audio Coding
and refers to an audio compression tech-
nology standard used with MPEG2 and
MPEG4.

of any electrical medical device other
than implantable cardiac pacemakers,
cardiac resynchronization therapy-pace-
makers or implantable cardioverter
defibrillators should consult the manufac-
turer of the device for information about
its operation under th e influence of radio
waves. Radio waves could have unex-
pected effects on the operation of such
