Adjusting for interpupillary distance
In order to see one singular image, you must adjust the two barrels of the
binoculars to your interpupillary distance (the distance from left pupil to right).
To do this, turn the barrels of the binoculars on their central hinge until you see
one singular field of view with no disturbing shadows.
Focusing your binoculars
The Denali features a large center focus knob along with a diopter adjustment
ring on the right ocular. The diopter adjusts for differences between your
individual eyes. The correct procedure for attaining proper focal balance using
the center focus knob and the diopter adjustment ring is:
A. Adjust the binocular barrels for your interpupillary distance.
(see top of page).
B. With your right eye closed (or with your hand over the right
objective lens), focus your left eye on a distant object with the
center focus wheel until the targeted object is in sharp focus.
C. Now adjust for your right eye. To do this, close your left eye
(or, again, place your hand over the left objective lens) and focus
your right eye on that same distant object. Focus using the diopter
adjustment ring until the object is sharply focused. Your binoculars
should now be adjusted to provide a clear and comfortable image.
