the power immediately and unplug the power cord from the AC outlet. Then
have the device inspected by qualified Yamaha service personnel.

from the AC outlet, the internal data is retained. However, if the backup
battery fully discharges, this data will be lost. When the backup battery is
running low, the display indicates "LoBT(Low Battery)." In this case,
immediately save the data to a Memory Card (CompactFlash), then have
qualified Yamaha service personnel replace the backup battery.
