Operating Adjustments
Adjusting and Using Your Binocular
Adjusting the binocular begins by setting the interpupillary distance.
This is the distance between the pupils of your eyes. The binocular tubes
pivot on a hinge, moving the tubes closer or further apart. Pivot the binocular
tubes until you see a single image when looking through the binocular.
How to Focus
• Choose an image, sign or a tree approx. 50 m away to view.
• Cover one of the objectives lenses.
• Look through the binocular with both eyes open.
• Turn the eyepiece
(1) of the uncovered lens until the image
appears clear and sharp
• Now repeat the procedure with the opposite lens.
• When viewing through both lenses, all images from 20 m to
infinity will be bright, clear and sharp.
• Make note of your diopter setting as it can be unique to each user.
• Higher power models (10x–20x) may require higher initial
focus distance.
When using binocular,
never point it directly at the sun.
