Solving Operation Problems
❒ Turn off the main power switch be-
fore pulling out the plug. If you
pull out the plug with the switch
on, the hard disk and memory may
be damaged and failure could re-
sult.
❒ Make sure that 100% is shown on
the display before you unplug the
machine. If a lower value is shown,
some data is currently present in
memory.
❒ Right after a power failure, the in-
ternal battery needs to be suffi-
ciently recharged to guard against
future data loss. Keep the machine
plugged in and the main power
switch on for about one week after
the power loss.
