rest reaches the same height as the patient's eye. At this moment, confirm that the eye height
mark of measuring window is at the height of the patient's visual line.
MEASUREMENT IN SEMI-AUTO MODE
If approaching the automatic measuring range, fine alignment and measurement are performed
automatically in Semi-auto mode.
SETTING THE SEMI-AUTO MODE
1 If the large sign "A" is displayed in the button with orange background, it is
in Semi-Auto mode.
2 If the large sign "A" is not displayed in the button with orange background, it
is in other mode. Tap the button to change to Semi-auto mode.
CAUTION
When operating the instrument (for measurement and control panel
operation), be careful that the instrument does not touch the
patient's lip or nose. If touched, clean the instrument as specified in
"CLEANING THE MEASURING WINDOW" on page 56.
NOTE
• Semi-auto mode measurement may not be possible, in case the eyelid
and the eyelashes cover the pupil.
If this occurs, the operator should tell the patient to open their eyes as
wide as possible, or lift the eyelid to allow for measurement.
• Semi-auto mode measurement may not be possible due to frequent blinks
or existing abnormalities in the corneal surface caused corneal disease
etc. In this case, measure in manual mode.
