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.

2. Diopter settings
3. Center focus wheel
How to adjust the eyecups:
If you wear sunglasses 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.
Note: It is important to protect this device from dust and moisture. When using in high humidity conditions, let the device acclimatize for a short period of time before storing so that residual moisture can dissipate.
