CUSTOMIZING THE RAZOR HD

Adjust the eyecups

The eyecups on a Razor 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

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.

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 until the

object is in focus. Make note of this diopter

setting in case you need to set it again.

To adjust the diopter

on the Razor HD,

pull out on the center

focus dial, rotate to

the proper diopter

setting, and push the

focus dial back in to

lock diopter position.

IPD

IPD is the distance between the

centers of the ocular lenses.

Rotate the binocular barrels

inward or outward to line your

eyes up with ocular lenses.

From this point on, you will only need to use the center focus wheel.
