right-hand diopter adjustment ring (4, red index)
– while still looking with both eyes through the
binoculars in a relaxed manner – so that you see
the target mark sharply.
5. Then adjust the image in the right-hand lens
sharply – with the target mark still displayed or
displayed again, but this time viewing with the
right eye – using the central focusing wheel.
Now look for an observation object at a range of
>100m.
6. Then adjust the image in the left-hand lens to
optimum focus using the left-hand diopter
adjustment ring (4).
7. You can read off the set values at the "+" or "-"
values of the diopter scales (4a).
Note:
When looking with only the left eye or right eye, the
other eye should be kept closed or simply cover the
4
front lens of the corresponding side of the
binoculars.
The viewing eye should be as relayed as possible.
