CD
The Setup CD section is primarily for defining parameters for a CD jukebox and for the programming of playlists.  Most CD jukeboxes allow a sequence of tracks to be programmed into it that it will later playback.
Maximum Songs in a Playlist
This parameter should be set to the maximum number of tracks that your jukebox will support being programmed at a time.  This is typically around 30.
Maximum Number of Jukebox Slots
This is the number of slots that your jukebox has.  In the case of Pioneer, many of their players have an extra slot for quick playing of a single CD.  You would not include this extra slot in the total.
Number of Digits when Programming Discs
This refers to the minimum number of digits to use when programming a playlist into your jukebox.  When programming a playlist into your jukebox, some manufacturers only require the necessary digits for a disc.  In this case, set this parameter to 0.  Other manufacturers may require a minimum of 2 digits.  An example would be programming disc number 8.  Some jukeboxes may require the disc to be programmed as 0 then 8.  Set the parameter to 2 in this case.
Number of Digits when Programming Tracks
This works the same way as Number of Digits when Programming Discs but sets the requirements for tracks instead of discs.
