Focus the Binocular
For the best results, follow this
two-step process to properly
adjust the Center Focus and
Diopter. Choose an object 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. Look
through the left barrel and adjust the
Center Focus wheel until the image is in
focus. Leave the Center Focus in
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 the
right barrel and adjust the Diopter until
the image is in focus. Make note of the
position of the Diopter setting in case
you need to set it again. From this point
on, you will only need to use the Center
Focus wheel.

BASIC OPERATION
Adjust the Eyecups
The Eyecups on Razor
®
UHD twist up and down allowing anyone
to obtain a full field of view and comfortable viewing despite
differences in facial structure and for use with or without glasses.
When not using glasses,
generally the Eyecups will be
fully extended. When using
glasses, generally the Eyecups
will be fully collapsed.
Adjust the Interpupillary Distance
The interpupillary distance (IPD) is the distance between the
centers of the left and the right eye pupils. Match the IPD of
your eyes to the binocular so that you see a single image free of
edge distortion.
IPD
Rotate the binocular barrels inward
or outward to line your eyes up with
Distance between the centers of
the ocular lenses.
