If the patient diopter is not in the range of -10 to +15 (D), focusing cannot be performed using the

In this case, use the diopter compensation function (see page 39) to focus with the cross-hair
line in the viewfinder.
When bringing the target into exact focus

focusing.

in the viewfinder and fundus image can be clearly seen at the same time.
