OPTIONAL OPERATIONS
3 Tap the button and focus on the patient's eye. The alignment
dot is reflected off-focus on the cornea.
4 When the main body is brought closer to the patient's eye, Z alignment arrows appear on the
control panel screen.
NOTE
• Do not allow the eyelash and eyelid to cover the outer alignment mark to
ensure stable measurement.
• If the machine is too close to the patient's eye in comparison with the opti-
mal alignment position, inward Z alignment arrows appear with a mes-
sage "BACKWARD," or if it is too far the arrows are changed to outward
with a message "FORWARD". The number of arrows are reduced accord-
ingly as the optimal alignment reference position comes closer.
