BASIC OPERATION
Adjust the Eyecups
The eyecups on a Viper®HD binocular twist up and down so any
viewer can see the full field of view and enjoy comfortable
viewing—with or without eyeglasses.
When not using eyeglasses or
sunglasses, keep the eyecups
fully extended. For the best
viewing when viewing through
eyeglasses, twist eyecups down.
Adjust the Interpupillary Distance
The interpupillary distance (IPD) is the distance between the
centers of the left and right eye pupils. Match youre eyes’ IPD
to the bonocular’s so that you see a single image that is free of
shading.
IPD
Rotate the binocular barrels inward
or outward to line your eyes up with
ocular lenses.
Distance between the centers of
the ocular lenses.

Properly Focus the Binocular
For the best views, follow this two-step process to properly adjust
the center focus and diopter. Choose an object about 20 yards
away and stay in the same spot until you have adjusted the
binocular for your eyes.
1. Adjust the center focus. Start by closing
your right eye or covering the right
objective lens with your hand. Focus
your left eye on the object and adjust
the center focus wheel until the image
is in focus. Leave the center focus in
this position as you adjust the diopter.
2. Adjust the diopter. Start by closing your
left eye or covering the left objective
lens with your hand. Look through
your right eye, pull the diopter ring
(found on the right eyepiece) toward
your eye, adjusting the diopter until
the object is in focus. Then, push the
diopter ring back down to lock your
settings. Make note of this diopter
setting in case you need to set it again. From this point on, you
will only need to use the center focus wheel.

LENS CARE
Maintain the optical brilliance of the Viper®HD binocular by
keeping lens surfaces free of dirt, oils, and dust.
Protect Lenses While Out in the Field
Make use of the provided eyepiece and tethered objective lens
covers to protect the lenses when not viewing. If the optics are
exposed to moisture, keep the caps off and allow the optics to dry
completely before putting them in the case for storage.
Keep Lenses Clean
In order to enjoy the best views through your binocular, take time
to regularly clean the exterior lenses:
1. Remove any dust or grit from lenses before wiping. Use a can of
pressurized air, soft camel hair brush, or an acrylic optical brush.
2. Clear lenses of smudges, fingerprints, or eyelash oil. Fog the
lenses with your breath, then use a non-abrasive lens cloth to
clean the lenses.
Note: Use lens cleaning fluid and optical paper to clean lenses. Never
use facial tissue, heavy cotton, or flannel clothing on lenses—these
materials can scratch the surface of a lens.
Caution: Binoculars are not intended for looking at the sun, or any
other intense light source. Such viewing could damage the retina
and cornea of your eyes—even to the point of causing blindness.
