Adjusting the Interpupillary Distance (IPD)
The interpupillary distance, or the distance between the pupils, varies from
person to person. The binoculars must be correctly aligned (adjusted)
to the distance between your pupils to achieve a single, clear image. To
adjust this distance, lift the binoculars up to your eyes (using both hands)
and look at an object in the distance. Move the two barrels (halves) of
the binoculars closer together or further apart until you see a single, clear
image. Check that the interpupillary distance is set correctly every time you
use your binoculars.
WARNING: Viewing the Sun may cause permanent eye damage. Do not
view the Sun with your binoculars or even with the naked eye.
Eyecup Adjustment
Leave the rubber eyecups up if you do not wear eyeglasses but fold them
down if you do wear eyeglasses to obtain the maximum field of view
Focusing
1. Adjust the interpupillary distance by moving the center hinge until you
see a single circular image.
2. The diopter adjustment ring is located directly below the right eyecup
(A). 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 binoculars). 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 binoculars as you
look into the eyepieces.
4. Using the center focus knob (B), 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 (A) to bring the object into focus in
the right side of the binoculars. Avoid over-turning or forcing the diopter
mechanism. If you are unable to bring the object into focus on the right
side by adjusting the diopter ring, make sure the left side is still focused
and that the center focus knob was not moved from its original setting.
The diopter adjustment only affects the right side.
7. Your binoculars should now be adjusted for your eyes. Focusing for any
distance can now be done simply by turning the center focus knob. (B)
