What is “Check-in/Check-out”?
After storing audio files on the hard disk of your computer, you can
transfer them to a digital music player, such as the CLIE handheld,
using OpenMG Jukebox.
Transferring audio files to a digital music player from your computer
is called “check-out.” Returning checked-out audio files to that
computer is called “check-in.”
You can check-out the same
song up to three times at any
one time.

If you check-in the song at
