FOCUS AND DIOPTER ADJUSTMENT
1. Adjust the eyecups and IPD as described in the previous sections.
2. Using a lens cap or your hand, cover the objective lens on the right side of the
binocular.
3. 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 when viewed through the left
side of the binocular.
4. Uncover the objective lens on the right side, and cover the left objective lens while
continuing to view the same object.
5. Rotate the diopter adjustment ring (NOT the center focus knob) located directly below the right eyecup (Fig. 4) 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 for your right eye by adjusting the diopter ring/eyecup, make sure the
left side is still in focus (repeat steps #2-4 if necessary). The diopter adjustment essentially provides "fine focus" on one
side of the binocular (right only) to allow for slight differences in the vision of your left and right eyes.
6. 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 your diopter setting (position of plus and minus marks on diopter ring relative
to index mark on binocular near the ring) for future reference in case the ring is moved accidentally or by another
person using your binocular.
NECKSTRAP ATTACHMENT
To attach the neckstrap, thread the ends of the neckstrap through the strap lug
(Fig. 5) on each side of the binocular, then back through the plastic buckle on the
strap (Fig. 6). Adjust the position of the binoculars on your chest as they hang around
your neck to your preference, by changing the length of the strap section which
passes through the strap channel and buckle by an equal amount on each side. If you
prefer to use an aftermarket strap that has metal O-rings, attach them to a plastic zip
tie placed on the strap lugs rather than installing them directly on the lug, to avoid
damaging the finish on the binocular via contact with the rings.
TRIPOD MOUNTING
To attach the binocular to a tripod or monopod, unscrew the cap which covers the
threaded (1/4-20UNC) socket at the far end of the center hinge (Fig. 7), and set it aside
in a safe place. Use a compatible binocular tripod adapter accessory (90
such as the Bushnell #161002CM, to attach your binocular on any standard tripod in a
horizontal position, to provide a stable image during prolonged viewing, especially with
high power optics. Tripod mounting not available on FRP models.
