Otherwise,
the data
on
the
memory disk
is lost
when
the
4395A
is
turned
o.
Backup is also
important as a means of recovering your precious data in the
event of a power
interruption or misoperation. F
or example
, even if you
inadvertently formatted the memory disk
while using the 4395A, you could
easily recover the data (les and disk format) from the backup copy; all you
have to do is turn OFF and ON the 4395A.
The memory disk can endure approximately 100,000 cycles of backup
operation.
