When turning off the main power switch and disconnecting the power plug
from the power outlet, the power is supplied between the SDRAM and the
super capacitor for image memory backup.
If the jumper plug (JP100) is disconnected with the image being backed up,
the contents in the memory are all cleared. Be sure to output all data in the
memory before disconnecting the jumper plug (JP100).
MEMO:
The jumper plug is small. A needlenose pliers or tweezers may be useful in
this operation. To prevent short-circuit, avoid contact of the jumper pin to a
nearby metal through the tool.
