FOCUSING
1. Adjust interpupillary distance. (Figure 1)
2. Set the “diopter setting” (Figure 2) to zero and view a distant object.
3. Keep both eyes open at all times.
4. Using a lens cover or your hand, cover the objective (front) lens of the
same side of the binocular that has the “diopter setting.” This is usually
the right side. (The left side on zoom models.)
5. Using the center focus wheel, focus on a distant object with fine detail
(e.g., brick wall, tree branches, etc.) until it appears as sharp as possible.
6. Uncover the objective lens on the diopter side, cover the other objective lens, then view the same object.
7. Using the “diopter setting” adjustment ring, focus the same object being viewed. Caution should
be used as over turning or forcing the diopter eyepiece can cause damage or cause the eyepiece to
break away from the chassis.
8. Your binocular should be adjusted for your eyes. Focus at any far or near distances can now be
attained simply by turning the center focus wheel. Make a note of the diopter setting for your eyes
for future reference.
EYECUPS (Figure 3)
Your Bushnell binocular is fitted with rubber roll-down eyecups designed for
your comfort and to exclude extraneous light. If you wear sun/eyeglasses, roll
down the eyecups. This will bring your eyes closer to the binocular lens thus
providing improved field of view.
