Playback may not occur in the above
hierarchy depending on the audio unit.: Track (File) : Folder
lThe folder order is automatically
assigned and this order cannot be
optionally set.
lAny folder without an MP3 file will be
ignored. (It will be skipped and the
folder number will not be displayed.)
lMP3 files not conforming to the MP3
format containing both header frames
and data frames will be skipped and
not played.
lThis unit will play MP3 files that have
up to eight levels. However, the more
levels a disc has, the longer it will take
to initially start playing. It is
recommended to record discs with two
levels or less.
lA single disc with up to 512 files can
be played and a single folder with up to
255 files can be played.
lWhen naming an MP3 file, be sure to
add an MP3 file extension (.mp3) after
the file name.
lThe number of characters which can be
displayed is restricted.
CAUTION
This unit can only play MP3 files that
have an MP3 file extension (.mp3)
attached. Do not attach an MP3 file
extension to any other type file as it
could cause noise to be emitted or a
malfunction in the unit.
About ID3 Tag display
lThis unit can only display ID3 Tag
album, track and artist names that have
been input using Ver.1.0/1.1/2.2/2.3/2.4
formats. Any other data that may have
been input cannot be displayed.
lThis unit cannot display some
characters. Characters which cannot be
displayed are indicated by an asterisk
(
).
Specialized glossary
MP3
Abbreviation for“MPEG Audio Layer 3”.
A technical standard for audio
compression as decided by the ISO
*1
MPEG working group. Use of MP3
allows for audio data to be compressed to
approximately a tenth of the source data
size.
*1 International Organization for
Standardization
ISO 9660
An international standard for logical
formatting of CD-ROM files and folders.
It is divided into three separate levels
based on differences in file naming
procedures, data configuration and other
characteristics.

Multi-session
A session is the complete amount of data
recorded from the beginning to the end of
a single period of CD-ROM, CD-R/CD-
RW data recording. Multi-session refers to
the existence of data from two or more
sessions on a single disc.
Sampling
Refers to the process of encoding analog
audio data at regular intervals and
converting it to digital data. The sampling
rate refers to the number of times a
sample is taken in one second and is
expressed in Hz units. Increasing the
sampling rate improves the sound quality
but also increases the data size.
Bit rate
Refers to the volume of data per second,
expressed in bps (bits per second).
Generally, the larger the number of the
transfer bit rate when compressing an
MP3 file, the more information regarding
musical reproduction it carries, and
therefore the better the sound quality.
Packet writing
A general term for the method, similar to
that used for floppy discs or hard drives,
of recording the required file in a single
increment on a CD-R and similar.
ID3 Tag
ID3 tag is a method for storing
information related to the music in an
MP3 file. Information such as track, artist
and album name can be stored. This
content can be freely edited using ID3
editing function software.VBR
Abbreviation for Variable Bit Rate. While
CBR (Constant Bit Rate) is generally
used, VBR varies the bit rate for audio
compression according to compression
conditions and this allows for
compression with preference given to
sound quality.
qOperating Tips for WMA
WMA is short for Windows Media Audio
and is the audio compression format used
by Microsoft.
Audio data can be created and stored at a
higher compression ratio than MP3.
* Microsoft and Windows Media are
registered trademarks of Microsoft
Corporation U.S. in the United States
and other countries.
Playable WMA files are as follows:
Item Content
SpecificationWindows Media Audio Version
7.0, 8.0, 9.0 (standard), 10.0
(standard)
Sampling rate 32/44.1/48 kHz
Bit rate 32―320 kbps
CAUTION
This unit plays files with the (.wma)
file extension as a WMA file. Do not
use the WMA file extension for files
other than WMA files. Otherwise, it
could result in noise or a
malfunction.
lTrack, artist and album name
information is recorded as data termed
“WMA-Tag”, and this information is
displayable.

lWMA files written under specifications
other than the indicated specification
may not play normally or files or folder
names may not display correctly.
lThe file extension may not be provided
depending on the computer operating
system, version, software, or settings.
In this case, add the file extension“.
wma”to the end of the file name, and
then write it to the disc.
qOperating Tips for AAC
AAC stands for Advanced Audio Coding,
which is standardized voice compression
established by the ISO
*1working group
(MPEG). Audio data can be created and
stored at a higher compression ratio than
MP3.
*1 International Organization for
Standardization
Playable AAC file specifications
This unit supports playback of AAC files
recorded in CD-R and CD-RW.
Playable AAC files are as follows:
Item Content
Specification MPEG-4 AAC
Sampling rate8/11.025/12 kHz
16/22.05/24 kHz
32/44.1/48 kHz
Bit rate 24―320 kbps
CAUTION
This unit plays files with the file
extension (m4a) as an AAC file. Do
not use the AAC file extension for files
other than AAC files. Otherwise, it
could result in noise or a
malfunction.
lSong, artist, and album name
information in the AAC file is recorded
as data termed“iTunes, m4a, Meta-
Data applicable”, and this information
is displayable.
lAAC files written under specifications
other than the indicated specification
may not play normally or files or folder
names may not display correctly.
lThe file extension may not be provided
depending on the computer operating
system, version, software, or settings.
In this case, add the file extension“.
m4a”to the end of the file name, then
write it to the disc.
qOperating Tips for USB device
This unit supports playback of MP3/
WMA/AAC files recorded to USB device.
NOTE
lMusic data (MP3/WMA/AAC (.m4a)
format) stored in a USB mass-storage class
compliant device (such as USB flash
memory) can be played.
lPlayback may not be possible depending on
the type and condition of the USB flash
memory even if the audio file complies with
the standard above.
lA copyright protected WMA/AAC file
cannot be played in this unit.
lThe order of the music data stored in the
device may differ from the playback order.
lTo prevent loss or damage of stored data,
we recommend that you always back up
your data.
lIf a device exceeds the maximum electric
current value of 500 mA, it may not operate
or recharge when connected.
