Vortex Optics CROSSFIRE II 10X42 ROOF PRISM BINOCULAR - Manual (Page 3)

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.
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 wheel.
The Crossfire II comes with a rainguard for the ocular lenses and
tethered objective lens covers. Use these covers to protect the
lenses whenever you are not viewing.
