FOCUSING/DIOPTER ADJUSTMENT
1. Adjust the interpupillary distance (Fig. 1) until you see a single circular image.
2. The diopter adjustment ring is located directly below the right eyecup.
(Legend Series L and M only): unlock the diopter adjustment before adjusting
it, by pulling the ring straight up (Fig. 2). This may be easier if you twist the
right eyecup up first (if you wear glasses, you can return the eyecup to the down
position after unlocking the diopter ring).
3. Start with the diopter adjustment set to "zero" (red index mark on diopter
ring is lined up with line between plus and minus marks on binocular). Keep
both eyes open at all times.
4. 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.
5. 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.
6. Uncover the objective lens on the right side, and cover the left objective lens
while continuing to view the same object.
7. Rotate the diopter adjustment ring 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 in 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 (repeat steps #3-6 if
necessary). The diopter adjustment only affects the right side.
8. (
Legend Series L and M only): once the diopter ring is set for your eyesight,
push the adjustment ring back down to lock it in place (Fig. 3).
