Eyecup Adjustment
Your binocular is fitted with eyecups which can be rolled or twisted up or down
(depending on your model) to optimize the view for your eyes and to exclude
extraneous light. If you are not wearing eyeglasses or sunglasses, keep the eyecups
fully extended (“up” position). If you are wearing glasses, roll down the eyecups or
twist them to the down position. This will bring your eyes closer to the binocular’s
eyepiece (ocular) lens to ensure you can see the entire image (full field of view with
no “cutoff” or “tunnel vision”).
IPD (Interpupillary Distance) Adjustment
The distance or spacing between the center of the pupils, called “interpupillary
distance” (IPD) varies from person to person. To adjust the binocular to match your
eyes, follow these simple steps:
1. Hold your binocular in the normal viewing position. Grasp each barrel firmly.
2. Move the barrels closer together or further apart until you see a single circular
field (don’t worry about focus yet).
3. Always re-set your binocular to this position before using it.

Diopter Adjustment and Focusing
1. Adjust eyecups interpupillary distance as described in the previous sections.
2. Set the diopter adjustment ring to zero and view a distant object.
3. Keep both eyes open at all times.
4. Using a lens cover or your hand, cover the objective (front) lens of the same side
of the binocular that has the diopter adjustment ring. This is usually the right side.
5. Using the center focus wheel, focus on a distant object with fine detail (e.g., brick
wall, tree branches, etc.) until it appears as sharp as possible.
6. Uncover the objective lens on the diopter side, cover the other objective lens, the
left side, then view the same object.
7. Using the diopter adjustment ring, move the dipoter adjustment marker to the “+”
or “-” till you reach focus.
Caution should be used as over turning or forcing the diopter ring can cause
damage or cause the eyepiece to break away from the chassis.
8. Your binocular should now be adjusted for your eyesight. Focusing for any
distance can now be done simply by turning the center focus wheel. Make a note of
your diopter setting for future reference.
Neckstrap Attachment (If included. Models will vary.)
To securely attach your binocular to the binocular strap:
1. Thread the end of the strap from the bottom up through the strap attachment
loop.
2. Hold the buckle and thread the end of the strap inside the buckle.
3. Adjust the overall length and pull the strap webbing tight so it is secure within the
buckle.
Waterproof / Fogproof Models (Models will vary.)
National Geographic binoculars are designed and built utilizing the latest waterproof
and fogproof technology (this will be noted on the product packaging). Waterproof
models are O-ring sealed for complete moisture protection. Fogproof protection is
achieved from dry nitrogen purging that removes all internal moisture.
Tripod Mounting (Models will vary. Tripod and tripod adapter not included.)
To attach the binocular to a tripod or mono-pod, unscrew (counter-clockwise) the
cap which covers the threaded socket at the far end of the center hinge, and set it
aside in a safe place. Use a compatible binocular tripod adapter accessory to attach
your binocular to any standard tripod in a horizontal position to provide a stable
image during prolonged viewing.
Care and Cleaning
Your National Geographic binocular will provide years of trouble-free service if it
receives the normal care you would give any fine optical instrument.
• Do not expose non-waterproof models to heavy rain or other excessive moisture.
• If your binocular has roll-down, flexible eyecups, store it with the eyecups up. This
avoids excessive stress and wear on the eyecups in the down position.
• Avoid sharp impacts. Use the included neckstrap to avoid accidentally dropping the
binoculars to prevent mis-alignment of the optics.
• When not using them, store your binoculars in the provided case in a cool, dry
place.
• Avoid storing the binoculars in hot places, such as the passenger compartment of
a vehicle on a hot day. The high temperature could adversely affect the lubricants
and sealants. Never leave the binocular where direct sunlight can enter either the
objective or the eyepiece lens. Damage may result from the concentration (burning
glass effect) of the sun’s rays.
• All moving parts of the binocular are permanently lubricated. Do not try to lubricate
them.
To Clean Your Binoculars Lenses
1. Blow away any dust or debris on the lens (or use a soft lens brush).
2. To remove fingerprints or other smears, clean with a soft cotton cloth rubbing in
a circular motion. A “microfiber”cleaning cloth (available from camera or computer
retailers) is ideal for the routine cleaning of your optics.
3. For a more thorough cleaning, photographic lens tissue and photographic-type
lens cleaning fluid or isopropyl alcohol may be used. Always apply the fluid to the
cleaning cloth – never directly on the lens.
