BEFORE USE : Screen Configuration
[Fundus observation screen]
In Normal photography mode
1. Optical working dot charts
Used as a guideline of the vertical position for proper image capture. When the two optical working dots are
clearly visible and positioned on the optical working dot charts, the image capturing unit is in a proper vertical
position for image capture.
2. Orientation tab
Used to show the orientation of captured images.
The orientation tab is not displayed for anterior eye images.
3. Focus split
Indicates the focus condition on the fundus by the displacement between the upper and lower lines.
The focus is optimum when a single line is formed by the upper and lower lines.
4. Fundus focus undetection mark
Indicates that the auto focus did not succeed (with the refractive error of the patient’s eye is outside the
range of -12 D and +15 D) when the anterior eye observation screen changed to the fundus observation
screen.
This mark blinks six times on the appearance of the fundus observation screen, then disappears. In such a
case, perform focusing by the focus knob.
