Eyecup Adjustment; Ipd (Interpupillary Distance) Adjustment; Focus And Diopter Adjustment; Neckstrap Attachment - Bushnell R Serie Bedienungsanleitung

WARNING: NEVER LOOK AT THE SUN THROUGH ANY OPTICAL INSTRUMENT. IT MAY PERMANENTLY DAMAGE
THE EYES.

EYECUP ADJUSTMENT

Your Bushnell R3 Binocular is fitted with eyecups that provide a comfortable view of the full image and help to exclude
extraneous light. If you need to wear glasses when using binoculars, leave the eyecup in the "down" position (Fig. 1, next page).
For use without eyeglasses or sunglasses, twist up the eyecups (Fig. 2). This will place your eyes farther from the binocular's
ocular lenses at the correct eye relief distance, allowing you to see the full field of view.

IPD (INTERPUPILLARY DISTANCE) ADJUSTMENT

The spacing between the pupils of your eyes, called "interpupillary
distance, " varies from person to person. To match your binoculars to
your IPD or "eye to eye" width:
1. Point them at a white wall or blank area of the sky. Hold the
binoculars and view through them as you normally would.
Don't worry about focus yet.
2. Grasp each side of the binocular firmly. Move the left and right
sides closer together or farther apart (Fig. 3, next page) until
you see a single image with no shaded areas.

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.
