Order of Play Tracks are played in the following order: File System and Naming The song name that displays is the name that is contained in the ID3 tag. If the song name is not present in the ID3 tag, then the radio displays the file name without the extension (such as .mp3) as the track name. Track names longer than 32 characters or four pages are shortened. The display does not show parts of words on the last page of text and the extension of the filename does not display. • The radio does not support playlist files. • Order of play differs depending if the compressed audio disc is fully scanned or unscanned. See "Scanning Compressed Audio Disc" previously in this section. • When playing an unscanned disc, the next and previous screen buttons may be required to switch away from the current folder when quickly seeking rather than allowing the last song of a folder to play to completion. Playing a Compressed Audio Disc As stated earlier in this section, the player can be used for CDs with conventional CD audio, MP3, or WMA compressed files. Read the information under "CD Player" for more information on playing an audio disc. • Play begins from the first track under the root directory. When all tracks from the root directory have been played, play continues from files according to their numerical listing. After playing the last track from the last folder, play begins again at the first track of the first folder or root directory. • A scanned compressed audio disc in artist/album modes only play songs within the current category. The next and previous screen buttons change to different artists or albums. When play enters a new folder, the display does not automatically show the new folder name. The new track name displays. 3-13
