If you wear eyeglasses, fold down the eyecups to bring your eyes closer to the ocular lenses, maximizing your field of viewSi vous ne portez pas de lunettes, laissez les œilletons en position relevée pour plus de confort. viewing.

4. Fonctionnement

1. Focusing Procedure:
   • Step 1 (Left Eye Focus): Close your right eye. Look through the left eyepiece at a distant object. Rotate the central focus wheel until the image in your left eye is sharp and clear.
   • Step 2 (Right Eye Diopter Adjustment): Close your left eye. Look through the right eyepiece at the same distant object. Rotate the diopter adjustment ring (typically located on the right eyepiece) until the image in your right eye is sharp and clear.
   • Step 3 (General Focusing): With both eyes open, your binocular is now adjusted for your vision. For subsequent focusing on objects at different distances, use only the central focus wheel.
2. Grand angle Viewment: The wide-angle design provides an expansive field of view (430' at 1000yds), which is particularly beneficial for observing fast-moving subjects or scanning broad landscapes without constantly repositioning the binocular.
3. Montage sur trépied: Pour une durée prolongée viewing sessions or to achieve maximum stability, the binocular can be mounted on a standard photographic tripod. Locate the binocular tripod socket, usually covered by a cap, at the front of the central hinge. A tripod adapter (sold separately) may be required to connect the binocular to your tripod.

5. Entretien

• Nettoyage des lentilles : Use the provided lens cloth or a soft, lint-free optical cleaning cloth to gently wipe the lenses. For stubborn smudges or dirt, apply a small amount of lens cleaning fluid specifically designed for optics onto the cloth, then gently wipe the lens surface. Never apply cleaning fluid directly to the lenses.
• Nettoyage du corps : Wipe the rubber armoring and body of the binocular with a soft, damp cloth. Avoid using abrasive cleaners, solvents, or harsh chemicals, as these can damage the finish and rubber coating.
• Stockage: When not in use, store the binocular in its protective carrying case in a cool, dry, and dust-free environment. Ensure the protective eye caps are in place to prevent dust accumulation and scratches on the lenses.
• Résistance à l'eau : The G-840WA features water-resistant construction, offering protection against light splashes and moisture. However, it is not designed for submersion in water. Avoid prolonged exposure to heavy rain or direct water spray.

6. Dépannage

• Image floue : If the image appears blurry, ensure you have followed the complete focusing procedure, including the diopter adjustment for your right eye. Check the lenses for any smudges, dirt, or condensation.
• Double image : A double image typically indicates incorrect interpupillary distance (IPD). Adjust the distance between the binocular barrels until you perceive a single, unified circular field of view.
• Difficultés de concentration : If the central focus wheel or diopter adjustment ring feels stiff or does not move smoothly, do not force it. Ensure no debris is obstructing the mechanism. If the issue persists, contact customer support.
