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
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. | 7 |
