” mark has not be pressed
accurately, press “Cancel” and re-do from the beginning.
Note:
As far as the Touch Panel Adjustment data is concerned,
the data is finalized when the touch is let go.
For this reason, the knack for adjustment is not to let go the
touch after touching the center section of the “
K
” mark.
After making the touch, first confirm that the touch is at the
dead center of the “
K
” mark. (This means that, if the touch
is not at the dead center of the “
K
” mark, maintain the touch,
and slide the stick to the dead center of the “
K
” mark.)
Then, let the touch go quickly, vertically upward.
