Thank you for purchasing a new Weaver® Classic Series Binocular. This manual will help you optimize your viewing experience by
explaining how you can adjust the binocular to your eyes, and how to care for this instrument. Read the instructions carefully before
using your binocular.
NEVER LOOK DIRECTLY AT THE SUN WITH YOUR BINOCULAR, AS IT MAY CAUSE SERIOUS DAMAGE TO
YOUR EYES!
EYECUP ADJUSTMENT
Your Weaver Classic Series 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). 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) 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.
