BASIC OPERATION

Adjust the eyecups

The eyecups on a Apresys 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.

Distance between the centers Rotate the binocular barrels inward or outward

of the ocular lenses. to line your eyes up with ocular lenses.

IPD IPD

Focus the binocular

For the best image, 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. 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. Looking through your right eye, adjust the diopter

so that the object is in focus.
