If you wear glasses, make sure the eyecups are in the down position — this will bring your eyes closer
to the binocular lens, allowing you to see the full field of view. To lower the eyecups from the full “up”
position, rotate them clockwise. The eyecups may also be left at positions “in between” fully up and fully
down, which may suit some individuals better.
FOCUSING
1. Adjust the interpupillary distance by adjusting the center hinge until you see a single circular
image.
2. The diopter adjustment ring is located directly below the right eyecup. Make sure the diopter
adjustment is set to “zero” for now (raised index tab on the diopter ring is lined up with center mark
on the binocular). Keep both eyes open at all times.
3. Using the attached lens cap or your hand, cover the objective (front) lens on the right side of the
binocular as you look into the eyepieces.
4. Using the center focus knob, focus on a distant object with fine detail (e.g., brick wall, tree
branches, etc) until it appears as sharp as possible on the left side.
5. Uncover the objective lens on the right side, and cover the left objective lens while continuing to
view the same object.
6. Rotate the diopter adjustment ring to bring the object into focus in the right side of the binocular.
Avoid over-turning or forcing the diopter mechanism. If you are unable to bring the object into
focus in the right side by adjusting the diopter ring, make sure the left side is still focused and
that the center focus knob was not moved from its original setting. The diopter adjustment only
affects the right side.
7. Your binocular should now be adjusted for your eyes. Focusing for any distance can now be done
simply by turning the center focus knob. Make a note of the diopter setting you made (index tab
position relative to the +/- scale) for future reference.
