How to adjust the distance between your eyes:

The distance between your eyes is called interpupillary distance. It varies from person to person. To achieve  perfect 

alignment of the lenses to eyes, follow these simples steps.  

1. Hold your binoculars in the normal viewing position.

2. Grasp each barrel firmly. Move the barrels closer together or further apart until you see a single circular field. 

Always reset your binoculars to this position  before using. Most binoculars have a graduated area at the top of the 

center hinge for reference in setting interpupillary distance for subsequent use.

How to adjust the diopter setting and center focus:

1. Adjust the diopter scale on the right eyepiece to 0. Look through the binoculars at an object about 150 feet away. 

2. Shut your right eye, and focus correctly for your left eye using the center focus wheel (3). 

3. Now shut your left eye, and adjust the focus for your right eye, using the diopter setting (2).  

4. Now the binoculars are correctly adjusted. You can vary the focus using the center focus wheel and both eyes will 

always remain in focus. Make note of the diopter setting on the right side, for future use.
