BASIC OPERATIONS
4 When the main body is brought closer to the patient's eye, alignment arrows appear on
the control panel screen.
Do not allow the eyelash and eyelid to cover the outer alignment mark to ensure
stable measurement.
If the machine is too near to the patient in comparison with the optimal alignment
position, the alignment arrows are displayed outward with the message "BACK-
WARD," or if it is too far from the patient, the alignment arrows are displayed
inward with the message "FORWARD." The number of arrow are reduced accord-
ingly as the optimal alignment reference position comes closer.
