Determine the area to be photographed.
Have the patient stare at the green internal eye fixation lamp. If necessary, press a FIX TARGET
switch to move the internal eye fixation lamp to guide the patientís eye. If you press the blink switch,
the internal eye fixation lamp blinks to make the lamp more noticeable to the patient and helps to
guide the patient’s eye. If the eye cannot be guided by the internal eye fixation lamp, use the external
eye fixation lamp.

Focus on patient’s eye.
Turn the focus knob to make the split lines into a single
line.
While the focus knob is being turned, the image
appears larger.
Concerning the external eye fixation lamp function
In the non-mydriatic mode, you can use either the internal eye fixation lamp or external eye
fixation lamp. The lamp to be used can be selected in the control software.
For details, refer to the Operation Manual of the control software.
Resetting the internal eye fixation lamp position
If you hold down the blink switch for approx. 2 or more seconds, the internal eye fixation lamp
blinks for 2 seconds and can be returned to its initial position.
When the split lines cannot be aligned
If the patient diopter is not in the range of -10 to +15 (D), focusing cannot be performed using the
focus indicator.
In this case, use the diopter compensation function
(see page 34)
to focus the image so that it
appears sharpest in the observation monitor.
