Operation
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 lookat 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.
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)
