OBJECTIVE OPERATIONS
For details about the illumination level setting, see "Setting the illumination level" on
page 38.
6 Bring the instrument even closer to the patient, and two bright spots for the working dis-
tance alignment become visible.
When the auto focus function is ON, the instrument changes the split lines into one line.
At this time, the fundus is almost in focus.
The auto focus mechanism will not work for ocular pathology (e.g. strong cataract), myo-
pia and hyperopia (beyond -13 to +12D), etc.
When the auto focus function is OFF, operate the focusing knob to change the split lines
into one line on the color LCD monitor.
7 Operate the control lever until the two alignment bright spots are changed to one spot.
8 Operate the control lever and move the instrument body to bring the bright spot into the ( )
scale on the color LCD monitor.
