B
Bit rate
This expresses the read amount per 1 second of video/audio data
recorded in a disc.
M
MP3 (MPEG Audio Layer-3)
This is an internationally standardized audio data compression scheme,
using the “MPEG-1” video compression standard. It compresses the
data volume to about one eleventh its original size while maintaining
sound quality equivalent to a music CD.
S
Sampling frequency
Sampling involves taking a reading of a sound wave (analog signal)
at regular intervals and expressing the height of the wave at each
reading in digitized format (producing a digital signal).
The number of readings taken in one second is called the “sampling
frequency”. The larger the value, the closer the reproduced sound is
to the original.
W
WMA (Windows Media Audio)
This is audio compression technology developed by Microsoft
Corporation.
WMA data can be encoded using Windows Media® Player Ver.7, 7.1,
Windows Media® Player for Windows® XP and Windows Media®
Player 9 Series.
To encode WMA fi les, only use applications authorized by Microsoft
Corporation. If you use an unauthorized application, the fi le may not
work properly.

n Playing CD-R/CD-RW discs
This unit can play back the CD-RW (ReWritable) discs as well as
ordinary Audio CD and CD-R (Recordable) discs.
• This unit can play back Audio CD format and CD-R/CD-RW discs
which contain MP3/WMA music data. However, some discs may
have problems such as unable to play, noise or sound distortion.
For details, please read the instruction manual provided with a
CD recorder.
• The CD-R and CD-RW discs should contain properly-recorded
TOC information so that they can be played back. In CD recorders,
the task of writing TOC information is referred to as fi nalizing the
disc. Discs that are not fi nalized cannot be properly recognized
as an Audio CD and played back by regular CD players and Super
Audio CD players. For details, please read the instruction manual
provided with a CD recorder.
* TOC stands for Table Of Contents and contains information such
as the total number of tracks and total playing time of the disc.
• This player can only be used to play Audio CD-DA format discs
or discs on which MP3 or WMA audio data have been recorded.
Do not attempt to play a disc containing other data, such as a
CD-ROM for PCs, on this unit.
• As the playback of a CD-RW disc necessitates partial change of
the player setup, it may take longer time for reading the TOC
information than when an Audio CD or CD-R disc is played.
n Playing MP3 or WMA fi les
This CD player can be used to play CD-R or CD-RW discs on which
MP3 (MPEG Audio Layer-3) or WMA (Windows Media Audio)
format audio fi les have been recorded.
Support for MP3 ID3 tags enables display of ID3 information,
such as artist names, album titles, track titles and the like, if this
information has been recorded with the tracks.
• Windows Media and the Windows are the registered trademark
and trademark of Microsoft Corporation in the United States and
other countries.
• Music that you have recorded that is subject to copyright laws is
for personal use only, and cannot be used otherwise without the
permission of the copyright holder.

Other specifi cations, such as MPEG-2 Audio Layer-3, MPEG-2.5
Audio Layer-3, MP1 or MP2 are not supported.
• Generally the higher the bit rate, the higher the sound quality.
MP3 bit rates are between 32 - 320 kb/s and for WMA between 64
- 160 kb/s. It is recommended that MP3/WMA recordings with a bit
rate of at least 128 kb/s be used.
• Ensure that MP3/WMA fi les have the extension “.mp3” or “.wma.”
Files with other fi le extensions or without any extension at all cannot
be played on this player.
• Playlists are not supported.

the maximum number of folders is also 255.
• File and folder names up to a length of 32 characters can be
displayed.
• This player supports MP3 ID3 tags.
• The text information, such as ID3 tag information and fi le names that
are displayed during playback of MP3s, support English alphanumeric
characters only.
• When playing variable bit rate fi les, it is possible that the playing time
may not be displayed accurately.
• When writing onto CD-R or CD-RW discs, please use either ISO9660
mode 1 or ISO9660 mode 2-disc format. Multi-session recording is
also supported enabling the playing of data that have been added
to a disc.
• MP3/WMA fi les that have been recorded by “packet writing” cannot
be played back.
• Depending on the condition of the recorded data, it may take some
time to read song information.
• In the case of an Enhanced or Mixed Mode CD having combined
audio format CD-DA along with MP3/WMA fi les, only the CD-DA
audio portion will be played.
• The playback of WMA DRM (Digital Rights Management) fi les is not
supported by this player.
