data of a CA-86 board is automatically restored when it has
been destroyed during startup of this unit.
In this case, perform the touch operation of a GUI screen
or the mouse-based operation according to the display on a
screen.
USB memory in which software was written may be
required halfway. Prepare the USB memory used during
