Timer expiration
It would be nice if when the timer expired to end the break that it could kickoff the music player.....assuming the caller was smart enough to load the next record (or maybe a default record). That way it would notify everyone to start to square up (including notifying the caller to get back).
From the CSDS main menu, select 'System | Settings...'.
Select the 'Timer' tab.
Under the 'Break timer' frame, you have options on what to do when the timer elapses.
