3. Setup
- Unpacking: Carefully remove the binoculars and all accessories from the packaging. Ensure all components are present: binoculars, carrying case, neck strap, lens caps, and cleaning cloth.
- Attaching the Neck Strap: Thread the neck strap through the strap lugs on each side of the binoculars. Adjust the length for comfortable carrying around your neck.
- Adjusting Interpupillary Distance (IPD): Hold the binoculars with both hands and look through them. Bend the body of the binoculars until you see a single, clear circular field of view. This adjusts the distance between the eyepieces to match your eyes.
- Adjusting Eyecups: If you wear eyeglasses, twist the eyecups down to their lowest position. If you do not wear eyeglasses, twist the eyecups up to achieve the optimal eye-relief.

4. Operating Instructions
- Focusing:
- Close your right eye and look through the left eyepiece with your left eye. Rotate the central focus wheel until the image is sharp.
- Close your left eye and look through the right eyepiece with your right eye. Rotate the right diopter adjustment ring (located on the right eyepiece) until the image is sharp.
- Now, with both eyes open, use only the central focus wheel to focus on objects at varying distances. The diopter setting should remain constant unless your eyesight changes.

5. Maintenance and Care
- Cleaning Lenses: Use the provided cleaning cloth or a soft, lint-free cloth to gently wipe the lenses. For stubborn dirt or smudges, use a few drops of lens cleaning fluid on the cloth, then wipe. Avoid using abrasive materials or excessive force.
- Storage: Store your binoculars in the carrying case in a cool, dry place when not in use. Avoid exposing them to direct sunlight or extreme temperatures for extended periods.
- Waterproof & Anti-Fog: While the binoculars are O-ring sealed and nitrogen-filled for waterproof and anti-fog performance, avoid submerging them unnecessarily. If they get wet, wipe them dry with a soft cloth.

6. Troubleshooting
- Blurry Image: Ensure both the central focus wheel and the diopter adjustment ring are correctly set for your eyes and the object's distance. Check for dirt or smudges on the lenses and clean if necessary.
- Double Image: Adjust the interpupillary distance (IPD) by bending the binocular body until a single circular field of view is achieved.
- Fogging: While the binoculars are anti-fog, extreme temperature changes can sometimes cause temporary internal fogging. Allow the binoculars to acclimate to the ambient temperature. If fogging persists, contact customer support.
- No Image: Ensure lens caps are removed from both objective and eyepiece lenses.
