Enjoy your ATRAC CD Walkman! The major specifications of the acceptable disc format are: • Maximum directory levels: 8 • Acceptable characters for a file/folder name: A - Z, a - z, 0 - 9, _ (underscore) Notes • When naming files, be sure to add the file extension "mp3" to the file name. • If you add the extension "mp3" to a file other than an MP3 file, the player will not be able to recognize the file properly. • The file name does not correspond to the ID3 tag*. *ID3 tag is a format for adding certain information (track name, album name, artist name, etc.) to MP3 files. The usable number of groups and files • Maximum number of groups: 100 • Maximum number of files: 400 Settings for compression and writing software • This CD player supports MP3 files with the following specifications: transfer bit rate: 16 - 320 kbps and sampling frequencies: 32/44.1/ 48 kHz. Variable Bit Rate (VBR) is also supported. To compress a source for an MP3 file, we recommend setting the transfer bit rate of the compression software to "44.1 kHz," "128 kbps," and "Constant Bit Rate." • To record up to the maximum capacity, set to "halting of writing." • To record at one time up to the maximum capacity on media that has nothing recorded on it, set to "Disc at Once." Notes on saving files on the media • Do not save files in other formats or unnecessary folders on a disc that has MP3 files. • When a disc is inserted, the CD player reads all the information of folders and files on that disc. If there are many folders on the disc, it may take a long time for play to begin or for the next file to start playback. 7
