Sony MZ-N1 OpenMG Jukebox NOTES on installing & operating Operating Instructions Manual page 78

Symptom
A track cannot be recorded
to a new group. A new group
cannot be created.
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
Group information has been written to the area where the
disc name is stored. The disc name and track names are
recorded in the same area, which can store a maximum of
approximately 1,700 characters. If the total number
exceeds this amount, a new group cannot be created even
though group mode is on. It is also impossible to make
group settings at this time.
This is due to a calculation discrepancy between the
recorder and the computer.
The minimum recordable time on a 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 a 2-second (or 4-
or 8-second) space for a track even if the track is under 2
seconds (or 4 or 8 seconds) in length. Also, the recorder
inserts a 2-second (or 4 -or 8-second) space in between
tracks during check out so as not to overwrite the previous
track by mistake. For this reason, the recorder needs an
additional 6 seconds (or 12 or 24 seconds) for each track.
This reduces the maximum recording time for each track
by 6 seconds (or 12 or 24 seconds) during check 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 USB
cradle to be calculated.
