Focusing the Binocular.
Choose an object that is about 20 yards away from you
and follow this two-step process to properly adjust
the focus. Be sure to stay in the same spot until you
have adjusted both the center focus and diopter.
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 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 dial.
Maintain the optical brilliance of the Raptor binocular
by keeping the lens surfaces free of dirt, oils, and dust.

Caring for the Lenses
Make use of the rainguard and tethered objective lens
covers to protect the lenses when not viewing. Store the
Raptor in its soft carry case.
Keep Lenses Clean.
Along with normal use comes the need to clean the
binocular lenses. Follow these guidelines for cleaning:
1. Remove any dust or grit from lenses before wiping.
Use a can of pressurized air or soft camel hair brush
(acrylic optical brushes also work well).
2. Clear lens of smudges, fingerprints, or eyelash oil.
Fog the lenses with your own breath and wipe with the
non-abrasive lens cloth included with the Raptor binocular.
Cleaning fluid and optical paper can also be used. However, you
should never use facial tissue, heavy cotton, or flannel clothing
on lenses—these materials can scratch the lens surfaces.
