This section describes the standard procedures for taking images using Auto fundus observation, AF 
(Auto-focus), and AS (Auto-shot) functions.

Align the retinal camera with the eye to be photographed. 

When adjusting the position of the retinal camera in the front-back direction, slowly bring the main 
unit closer to the patient while looking at the patient’s eye from the side. The patient’s eye may be 
injured if the objective lens makes contact with it.

1.  Move the stage until the eye to be photographed appears on the observation monitor. 
2.  Adjust the center of the patient's pupil and the pupil alignment circles. 
3.  Have the patient stare at the green blinking internal eye fixation lamp. 

Pupil alignment circles 

During examination of the anterior segment of a patient who is extremely near- or far-sighted, the 
patient may not be able to see the internal eye fixation lamp. 

•  To move the main unit slightly to the left or right, tilt the 

operation lever to the left or right. 

•  To move the main unit slightly to the front or back, tilt the 

operation lever to the front or back. 

•  To move the main unit up or down, turn the main unit 

vertical movement ring. 

When the vertical position cannot be fully adjusted by using the operation lever 
Adjust the height of the chin rest with the CHIN REST button to raise or lower the patient's face. 

Tilt the operation lever forward or backward to unify the top and bottom of the image of 
the pupil.
