Vortex Viper HD 10x42 User manual

IPD
The eyecups on a Viper HD binocular twist up and down so any viewer can see
the full field 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 the IPD of your eyes to that of the binocular so that
you see a single image that is free of shading.
CUSTOMIZING THE VIPER HD

Rotate the binocular barrels inward
or outward to line your eyes up with

ACCESSORIES FOR THE VIPER HD
Attach the padded neckstrap to the Viper HD in three simple steps.
Begin with the right barrel of the binocular and repeat the process for
the left barrel.
Neckstrap
1. Push a few inches of
the strap through the
strap attachment on the
binocular.
3. Adjust the overall
length, then pull the tight
until strap secured within
the buckle.
2. Hold the buckle
and thread the end of
the strap through the
buckle.
Note: If using another type of strap, never attach metal O-rings directly onto
the strap attachment.
Properly focus the binocular
For the best views, follow this two-step process to properly adjust the
center focus and diopter. Choose an object that is about 20 yards
away from you 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.
Adjust the diopter—start by closing your left eye or covering the left
objective lens with your hand. Look through
your right eye and adjust the diopter (ring found
on the right eyepiece) until the object is in
focus. 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.
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.

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 objective lens covers to protect
the lenses when not viewing. Then, store the Viper HD in its carry
case between viewing sessions.
Keep lenses clean
In order to enjoy the best views through your Viper HD 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 own 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.
