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

Focusing:
1. Set the right eyepiece (A) to zero and sight on a distant subject.
2. Cover the right front lens with your hand and rotate the focusing wheel (B) until the image in the left eyepiece appears sharp. Keep both eyes open while you make this adjustment.
3. Now cover the left front lens with your hand and rotate the right eyepiece 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.

Notes:
1. Never attempt to clean your binocular internally or try to take it apart.
2. Viewing the sun can cause permanent eye damage. Do not view the sun with this product.
