• This product allows playback of MP3 files on CD-ROM, CD-R or CD-RW discs.
• The unit can read MP3 files written in the format compliant with ISO 9660.
However it does not support the MP3 data written by the method of packet write.
• The unit can not read an MP3 file that has a file extension other than “mp3”.
• If you play a non- MP3 file that has the “mp3” extension, you may hear some noise.
• In this manual, we refer to what are called “MP3 file” and “ folder” in PC terminologyas “ track
and album”, respectively.
• Maximum number of directory level is 8, including the root directory. Maximum number of files
and folders per disc is 256.
• The unit may not play tracks in the order of Track numbers.
• The unit plays only the audio tracks if a disc contains both audio tracks and MP3 files.
• When playing a disc of 8 kbps or “VBR”, the elapsed playing time in the display window will
not be correct and also the intro play may not function properly.
“VBR”: Variable Bit Rate.
• The unit supports the playback of WMA files. The playback of ID3 tags for WMA format is not
guaranteed, it depends on versions and availability of Cyrillic alphabet.
• WMA (Windows Media Audio) music data compression format, created by Microsoft
Corporation. This format uses coding algorithm for compression of initial audio-record, greatly
decreasing the file size, but, saving the good sound quality even when the bit rate is low (for
example, 64 Kbit/s).
• Remember that the unit may not play the tracks in order they are written on disc.
Notes on creating your own CD-R or CD-RW containing MP3 files:
• To enjoy high quality sound, we recommend converting to MP3 files with a sampling frequency
of 44.1kHz and a fixed bit rate of 128 kbps.
• DO NOT store more than 256 MP3 files per disc.
• For ISO 9660 - compliant format, the maximum allowable depth of nested folders is 8,
including the root directory (folder).
• When CD-R disc is used, playback is possible only for discs, which have been finalized.
• Make sure that when MP3 CD-R or CD-RW is burned that it is formatted as a data disc and
NOT as an audio disc.
• You should not write non-MP3 files or unneeded folders along with MP3 files on the disc
otherwise it takes a long time until the unit starts to play MP3 files.
• With some CD-R or CD-RW media, data may not be properly written depending on its
manufacturing quality. In this case, data may not be reproduced correctly.
High quality CD-R or CD-RW disc is recommended.
• Up to 16 characters are displayed for the name of an Album or a Track. ID3TAG version 1x is
required.
• Note that the unit may not play Tracks in the order that you wrote them to the disc.
