3.2 Adjusting Interpupillary Distance

Hold the binoculars with both hands and look through the eyepieces. Adjust the distance between the two barrels by moving them closer together or further apart until you see a single, clear circular field of view. This ensures both eyes are aligned with the optical path.

3.3 Focusing

1. Center Focus: Look through the binoculars at a distant object. Use the central focusing wheel to bring the image in your left eyepiece into sharp focus.
2. Diopter Adjustment: Close your left eye and use the diopter ring on the right eyepiece to focus the image in your right eyepiece. This compensates for differences in vision between your eyes.
3. Once both are set, use only the central focusing wheel for subsequent focusing.

3.4 Eyecup Adjustment

The eyecups can be twisted up or down to provide comfortable viewing, especially for spectacle wearers. Twist them down if you wear glasses to ensure a full field of view, and twist them up if you do not wear glasses.

4. Operating Instructions

Once properly set up, your BRESSER 8x25 Binoculars are ready for use. Hold them steady and use the central focus wheel to adjust for clear images of various distances. The waterproof and fogproof design allows for reliable performance in diverse weather conditions.

5. Maintenance

5.1 Cleaning Lenses

Use the provided lens cleaning cloth to gently wipe dust or smudges from the lenses. For stubborn marks, a small amount of lens cleaning fluid designed for optics can be applied to the cloth, not directly to the lens. Avoid using abrasive materials or excessive force, as this can scratch the lens coatings.

5.2 Storage

When not in use, store your binoculars in the provided carrying bag to protect them from dust, moisture, and impacts. Store in a cool, dry place away from direct sunlight and extreme temperatures.

6. Troubleshooting

• Blurry Image: Ensure both the central focus wheel and the diopter adjustment are correctly set for your eyes and the viewing distance.
• Fogging: While the binoculars are argon-purged and fogproof, extreme temperature changes can sometimes cause temporary external condensation. Allow the binoculars to acclimate to the ambient temperature.
• Double Image: Re-adjust the interpupillary distance until a single, clear circular field of view is achieved.
