ENGLISH
	file format with a data compression ratio of 1:10
	MP3 is an abbreviation of Motion Picture Experts
	Group (or MPEG) Audio Layer 3. MP3 is simply a
	(128 Kbps*). That means, by using MP3 format,
	one CD-R or CD-RW can contain 10 times as
	much data volume as a regular CD can.
	* Bit rate is the average number of bits that one
	second of audio data will consume. The unit
	used is Kbps (1024 bits/second). To get a
	better audio quality, choose a higher bit rate.
	The most popular bit rate for encoding is 128
	Kbps.
	This unit is incorporated with an MP3 decoder.
	You can play back MP3 files (tracks) recorded on
	CD-Rs, CD-RWs, and CD-ROMs.
	Compatible with ID3v1 (Version 1)

Precautions when recording MP3 files on a CD-R or CD-RW

This unit can only read MP3 files that are recorded in the format that is compliant with ISO 9660 Level 1, Level 2, or Joliet.

How are MP3 files recorded and played back?

MP3 “files (tracks)” can be recorded in “folders” —in PC terminology.

During recording, the files and folders can be arranged in a way similar to arranging files and folders of computer data.

“Root” is similar to the root of a tree. Every file and folder can be linked to and be accessed from the root.

Playback order, file search order, and folder search order of the MP3 files recorded on a disc are determined by the writing (or encoding) application; therefore, playback order may be different from the one you have intended while recording the folders and the files.

The illustration on the next page shows an example of how MP3 files are recorded on a CD-R or CD-RW, how they are played back, and how they are searched for on this unit.

Notes:

•The unit can read a CD-ROM containing MP3 files. However, if non-MP3 files are recorded together with MP3 files, this unit will take a longer time to scan the disc. It may also cause the unit to malfunction.

•The unit cannot read or play an MP3 file without the extension code—mp3.

•This player is not compatible with the data encoded with Layer 1 and Layer 2 formats.

•The unit is not compatible with Playlist**.

**A playlist is a simple text file, used on a PC, which enables users to make their own playback order without physically rearranging the files.
