4) When backup data cannot be uploaded before replacement due to reasons such as
damage of the DC Controller PCB, enter the value of each #PRINT item described on the
service label.
Since the values recorded on the service label may not be the latest at this time, check the
service mode item list (#SERVICE DATA LIST) printed out in advance, and enter the values
on the list.

CAUTION:
Even after turning OFF the main power switch and disconnecting the power plug from
the outlet, power is still supplied between SO-DIMM and Secondary Battery Unit for
backup of the image memory. When the SW3 of the Main Controller PCB is pressed
while image is backed up, all the contents in the memory are cleared, therefore be sure
to output all data in the memory before pressing it.
