What are MP3 files? MP3 (MPEG 1 Audio Layer-3) is a standardised technology and format for the
compression of sound sequen ces. The sound file is compressed to about
1/10th of its original size. Sounds th at are out of the human hearing range
are excluded while those that are within the range are compressed.Accepted recording formatsIt is possible to play MP3 files recorded on CD-ROMs, CD-Rs and CD-RWs. The unit supports MP3 discs that have been formatted using the ISO 9660
standard level 1 or 2. The unit can also play discs recorded using the Romeo

8.3 format (8 characters maximum for the name of the file + 3 characters for
the extension “.MP3”. Folder names ca
nnot be more than 8 letters long.

information on each recorded CD is contained within an area marked by two
data labels called “Lead-in” for the be ginning of the area and “Lead-out” for
the end of the area. A multi-session CD will allow for multiple segments that
contain their own “Lead-in” and “Lead-out”.
