3) For the model with a FAX and SEND function, press the SW3 on the main controller to
check that LED10 goes out. (Secondary power cutoff)
CAUTION:
The ADRAM is powered from the secondary battery unit to back up the image memory
even after the main power switch is turned OFF and the power plug is removed from
the outlet.
If the SW3 on the main controller PCB is pressed with the image backed up, the entire
data stored in the memory is cleared. Be sure to output the data stored in the memory
before pressing the SW3.
