BASIC OPERATIONS
5 Keeping the luminous point within the alignment mark, slowly move the main body toward
the patient.
When the main body approaches the target eye, the alignment bar of the monitor screen
changes to arrows.
Take care so that eyelashes and eyelid do not come into the minimum pupil diam-
eter mark as they may disturb measurement.
If the instrument is too close to the alignment reference position, “ÅÆ” is dis-
played on the monitor screen, and if too far, “ÆÅ” is displayed.
