About MP3

MP3 (MPEG 1 Audio Layer-3) is a standard technology and format for compressing a sound sequence. The file is compressed to about 1/10 of its original size. Sounds outside the range of human hearing are compressed while the sounds we can hear are not compressed.

Notes on discs

You can play MP3 audio tracks recorded on CD-ROMs, CD-Rs (recordable CDs), and CD-RWs (rewritable CDs).

The disc must be in the ISO 9660* level 1 or level 2 format, or Joliet in the expansion format.

*ISO 9660 Format

The most common international standard for the logical format of files and folders on a CD-ROM. There are several specification levels. In Level 1, file names must be in the 8.3 format (no more than eight characters in the name, no more than three characters in the extension “ .MP3” ) and in capital letters. Folder names can be no longer than eight characters. There can be no more than eight nested folder levels. Level 2 specifications allow file names and folder names up to 31 characters long. Each folder can have up to 8 trees.

For Joliet in the expansion format (file and folder names can have up to 64 characters), make sure of the contents of the writing software, etc.

Notes

•Only the letters in the alphabet and numbers can be used for album or track names. Anything else is displayed as “ ” (space).

•When naming, be sure to add the file extension “ MP3” to the file name.

•If you put the extension “ MP3” to a file other than MP3, the unit cannot recognize the file properly and will generate random noise that could damage your speakers.

•The following discs take a longer time to start playback.

•Depending on the encoding/writing software, recording device, or the recording media used at the time an MP3 file is recorded, you may encounter such problems as disabled playback, sound interruptions, and noise.
