OPERATION
MP3 Disc compatibility with this unit is limited as
follows:
1. Sampling Frequency / 22.05 - 48kHz (MP3),
2. Bit rate / within 16 - 320kbps (include VBR) (MP3),
3. CD-R/CD-RW physical format should be “ISO 9660”
4. If you record MP3 files using software which cannot create a
FILE SYSTEM, for example “Direct-CD” etc., it is impossible to
playback MP3 files. We recommend that you use “Easy-CD
Creator” which creates an ISO9660 file system.
5. Folder or File names should have a maximum 22 letters or less.
ID3 TAG: Title, Artist or Album names should have a maximum
30 letters or less.
The file have an “.mp3” extension e.g. “********.MP3”.
