Adjusting and using your binoculars

ADJUSTING THE OPTICAL VIEW 

The distance between the eyes varies from one person to the next. To achieve perfect alignment of the eyes and the lens openings, hold the binocular in the normal viewing position and move the two barrels either apart or closer to each other until you have a single, clear field of view. 

FOCUSING YOUR BINOCULAR 

1. Set the diopter adjuster (A) to the center position. 
2. Cover the right front lens with your hand and rotate the focusing wheel (B) until the image in the left eyepiece appears sharp. 
3. Now cover the left front lens with your hand and rotate the diopter adjuster (A) until the image is sharp. 
4. The binoculars have now been adjusted to your eyes. Note the diopter reading of the right eyepiece for future reference. 

TWIST-UP EYE CUPS 

Eyeglass users will normally need the eye cups (C) twisted down. Users not wearing eyeglasses should adjust the eye cups upwards for optimum eye relief.
