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.

Parts:

1. Eyepiece/Eyecups

2. Diopter

3. Focus Wheel

How to adjust the diopter setting and center focus:

1. Adjust the diopter scale on the right eyepiece to 0. 

Look through the binoculars 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.

How to adjust the eyecups:

If you wear sun or eyeglasses, fold down the eyecups (1).

This will bring your eyes closer to the lenses thus providing an improved field 

of view.

How to clean:

1. Blow away any dust or debris on the lens (or use a soft lens brush).

2. To remove dirt or fingerprints, clean with a soft cotton cloth by rubbing in 

a circular motion. Use of a coarse cloth or unnecessary rubbing may scratch 

the lens surfaces and eventually cause permanent damage to the binoculars.

3. To thoroughly clean your binoculars, you may use a  photographic - lens 

cleaning fluid. Always apply the fluid to the cleaning cloth, never directly onto 

the lens.
