Symptom
The playing time of a
checked-out track is
different from the time
that appears on your
computer monitor.
You cannot check out
tracks that will fill up
the remaining recording
time on the disc. (For
example, you cannot
check-out tracks that
total 160 minutes to an
80-minute disc in LP2
stereo mode.
You cannot erase a
track checked out from
your computer.
When using with the
AC power adaptor, the
display window of the
recorder will remain
faintly lit for some time
even after the recorder
is stopped.

Cause
This is due to a calculation discrepancy between the recorder
and the computer.
The minimum recordable time on the disc is normally 2
seconds in stereo, 4 seconds in LP2 stereo mode, and 8 seconds
in LP4 stereo mode. When you check-out a track from your
computer the recorder needs 2 seconds (4 or 8 seconds)-space
for one track even though the track is under 2 seconds (4 or 8
seconds) length. Also the recorder inserts 2 seconds (4 or 8
seconds)-space between tracks when checking out in order not
to erase the previously recorded track or not to be erased by
recorded over. For this reason, the recorder needs 6 seconds (12
or 24 seconds) longer time for a track so that as a result, the
recordable time of the disc become 6 seconds (12 or 24
seconds) shorter than the maximum recordable time of the disc
when checking out.
To erase a track that has been checked out from your computer,
check it back in first, and then erase it using the OpenMG
Jukebox software.
The recorder turns off 3 minutes after the recorder has stopped
in order to allow the charging time on the battery charging stand
to be calculated.
