Technical Information for MP3 Player (US8, US9, or U3L)

The MP3-capable radio will play both standard audio CDs and CD-Rs. The CD-Rs may contain standard audio format (*.cda) or compressed audio in the *.mp3 format.

Customers who make their own music CD-Rs should be aware of the following:

• The files can be recorded on a CD-R disc with a maximum capacity of 700 MB.
• The MP3 files must be recorded onto the disc in either a fixed bit rate (32 kbps, 40 kbps, 48 kbps, 56 kbps, 64 kbps, 80 kbps, 96 kbps, 112 kbps, 128 kbps, 160 kbps, 192 kbps, 224 kbps, 256 kbps, and 320 kbps), or in a variable bit rate.
• Discs recorded in either one session or in multiple sessions will play. Playlists, such as those created with popular MP3 software, are also supported.
• ID3 tag information is available during playback, providing the information was recorded with ID3 tags, version 1 or version 2. CD text information is not available with the US8 radio.
• The radio does not play mixed media CDs, those that contain files in both the *.mp3 and the *.cda format.
• The radio will not play CD-Rs that contain formats of compressed audio other than *.mp3, such as *.wma, *.asf, or *.aac.
• The radio will support a maximum of 50 folders, 50 playlists, 10 sessions, and 255 files. If the information on the disc exceeds these numbers, anything over the maximum allowable will be ignored. Files that are not in the *.mp3 format will not play, but do count toward the maximum number of files.
• The files or playlists can be arranged in folders, up to 11 layers deep, folders within folders, within folders, etc. Anything more than 11 layers deep will be ignored.
• Long names (on files, folders, playlists) or combination of large number of folders and files or playlists may cause player not to be able to read up to the max numbers of folders, playlists, files, or sessions, due to memory limitations. Customers are encouraged to keep shorter names and minimize folder depth for ease of operation.

If these guidelines are not followed, a customer recorded CD may not play. Note that the radio has no ability to record *.mp3 files or any audio to a CD-R, it has only the ability to read information on a CD-R.
