If subject's eyelid or eyelashes covers his/her pupil, the measurement in auto mode might not be performed. In
these cases, ask him/her to open his/her eye wider or to pull up his/her eyelid with his/her hand.
The auto mode might not work for a patient with frequent blinking or with abnormality on the corneal surface due
to a corneal disease and others. In this case, take measurements in manual mode.
The auto alignment function might not work for a patient with glittering eye makeup on her eyelid or its peripheral.
In this case, take measurements in manual mode.
Operate this device with great care because a part of this device might come into contact with a subject's eye or
nose.
If tapping the area other than the one around the pupil, alignment cannot be performed normally, and a part of the
device might come into contact with a patient's nose.
Check the measurement screen.
If the indication of the 3D Auto/Manual switch is “3D A”, it means you are in auto mode.
If the indication is “3D M”, switch it to the auto mode by tapping it.
Alignment can be performed on the LCD touch panel.
Before performing alignment, it is necessary to calibrate the center position of the pupil and focus position manually.
Perform alignment so that the center of the pupil is placed in the reticle by pressing down the screen.
