3. What's in the Box
Upon opening your Leacco 10x25 Compact Binoculars package, you should find the following items:
- 1 x Leacco 10x25 Compact Binoculars
- 1 x Storage Bag
- 1 x Lens Cleaning Cloth
- 1 x Neck Strap

4. Setup and First Use
Follow these steps to set up your binoculars for optimal viewing:
- Adjust Eyecups: Rotate both eyepiece lenses (adjustable rotating eyecups) upward until they are fully extended. This ensures your eyes do not touch the lenses, especially if you wear glasses.
- Adjust Interpupillary Distance: Hold the binoculars up to your eyes and adjust the distance between the two barrels until you see a single, circular field of view without any dark edges or double images.
- Focus the Left Eye: Close your right eye and look through the left eyepiece. Rotate the central focus wheel until the image in the left eyepiece is clear and sharp.
- Focus the Right Eye (Diopter Adjustment): Keep your left eye closed and look through the right eyepiece. Rotate the diopter adjustment ring on the right eyepiece until the image is clear and sharp. Once set, this adjustment typically does not need to be changed unless a different user with significantly different vision uses the binoculars.
- Fine-Tune Focus: With both eyes open, use the central focus wheel to make minor adjustments for overall image clarity as you view different distances.

To get the most out of your Leacco binoculars, consider the following operational tips:
- Steady Viewing: For the steadiest image, hold the binoculars with both hands. If possible, brace your elbows against your body or a stable surface.

6. Maintenance
Proper care and maintenance will extend the life and performance of your binoculars:
- Lens Cleaning: Use only the provided lens cleaning cloth or a soft, lint-free cloth specifically designed for optics. Gently wipe the lenses to remove dust or smudges. Avoid using abrasive materials or harsh chemicals.
- Storage: When not in use, store your binoculars in the included storage bag to protect them from dust, dirt, and scratches. Keep them in a cool, dry place.
- Avoid Extreme Conditions: Do not expose the binoculars to extreme temperatures (very hot or very cold) for prolonged periods, as this can affect the internal components and coatings.
- Handle with Care: Although shock-resistant, avoid dropping or subjecting the binoculars to severe impacts.
7. Troubleshooting
If you encounter issues with your binoculars, refer to the following common solutions:
- Unclear Image: If the image appears blurry, re-adjust the central focus wheel and the right-lens diopter ring as described in the "Setup and First Use" section. Ensure the interpupillary distance is correctly set for a single, clear field of view.
- Fogging Lenses: These binoculars are fog-resistant due to nitrogen filling. If fogging occurs, it may be due to extreme temperature changes on the exterior. Allow the binoculars to acclimate to the ambient temperature. Ensure lens caps are on when not in use to prevent moisture buildup.
- Water Exposure: The binoculars are IPX7 waterproof, meaning they can withstand immersion in water up to 1 meter for 30 minutes. If exposed to water, wipe them dry with a soft cloth. Do not attempt to disassemble them.
