to move the measuring head to a position that alignment is possible.

tion, “Reaching set limit of stopper. Move measuring head.” is displayed,
and when it is at the limit of movement in the backward direction, “FAR
LIMIT” and the blue arrow prompting movement in the forward direction
are displayed. If the position is detected, “TOO CLOSE” is displayed at a
position closer than 4 mm to the patient’s eye. Check the position of the
patient’s face and the height of the chinrest, and using the
