Frequently Asked Questions - 80-10821CP National Geographic

How do I focus the binoculars?

Use the center focus wheel to adjust for your left eye first, then use the diopter adjustment ring on the right eyepiece to fine-tune for your right eye. Once set, you can refocus using the center wheel for both eyes.

How do I set the diopter?

Set the diopter scale to 0. Focus with your left eye using the center wheel, then adjust the diopter ring for your right eye while keeping your left eye closed. Note the setting for future use.

Can I use these binoculars while wearing glasses?

Yes, fold down the rubber eyecups to bring your eyes closer to the lenses, providing a better field of view.

What is the interpupillary distance and how do I adjust it?

Interpupillary distance is the space between your eyes. To adjust, hold the binoculars and move the barrels closer or further apart until you see a single circular field. Most binoculars have a scale on the hinge for reference.

How do I clean the lenses?

Blow away dust or use a soft lens brush. For dirt or fingerprints, clean with a soft cotton cloth in circular motions. You can use photographic lens cleaning fluid applied to the cloth, not directly on the lens.

Is it safe to look at the Sun with these binoculars?

No, never look at the Sun even for a moment. It can cause instant and irreversible eye damage or blindness. Also avoid pointing the device at the Sun.

Are these binoculars waterproof?

The manual does not specify waterproofing. They should be protected from dust and moisture. After use in high humidity, let them acclimatize before storing to dissipate moisture.

What should I do if the binoculars are damaged?

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.
