Setup
- Unpack and Inspect: Carefully remove the binoculars and all accessories from the packaging. Inspect for any signs of damage.
- Attach Neck Strap: Thread the neck strap through the attachment points on the binoculars. Ensure it is securely fastened to prevent accidental drops.
- Adjust Interpupillary Distance: Hold the binoculars up to your eyes. Adjust the distance between the two barrels by moving them closer or further apart until you see a single, circular field of view.
- Diopter Adjustment:
- Close your right eye and look through the left eyepiece. Rotate the central focus wheel until the image is sharp.
- Close your left eye and look through the right eyepiece (which has the diopter ring). Rotate the diopter ring until the image is sharp.
- Now, with both eyes open, the binoculars should be adjusted for your vision. Use only the central focus wheel for subsequent focusing.

Operating Instructions
General Use
- Remove all lens caps.
- Hold the binoculars firmly and bring them to your eyes.
- Adjust the interpupillary distance as described in the Setup section until you see a single, clear circle.

Using the Phone Adapter
The included phone adapter allows you to connect your smartphone to the binoculars to capture magnified images or videos.

Maintenance
- Cleaning Lenses: Use the provided lens cleaning cloth or a soft, lint-free cloth specifically designed for optics. Gently wipe the lens surfaces. For stubborn smudges, use a small amount of lens cleaning fluid on the cloth, not directly on the lens.
- Cleaning Body: Wipe the rubber armor with a soft, damp cloth. Avoid harsh chemicals or abrasive materials.
- Storage: Store the binoculars in their carrying bag in a cool, dry place when not in use. Avoid extreme temperatures and high humidity. Always replace lens caps to protect the lenses from dust and scratches.
- Waterproofing: While the binoculars are IP67 waterproof, avoid prolonged submersion or exposing them to high-pressure water jets. After exposure to water, wipe them dry with a soft cloth.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Blurred image | Incorrect focus; Diopter not adjusted; Dirty lenses | Adjust central focus wheel; Perform diopter adjustment (see Setup); Clean lenses with lens cloth. |
| Double image or two overlapping circles | Interpupillary distance not set correctly | Adjust the distance between the barrels until a single, circular field of view is achieved. |
| Fogging inside lenses | Rapid temperature change; Seal compromise (unlikely due to nitrogen-filling) | Allow binoculars to acclimate to ambient temperature. If fogging persists, contact customer support. |
| Difficulty attaching phone adapter | Phone camera not aligned; Adapter not securely fastened | Ensure phone camera is centered over the adapter's opening. Tighten adapter securely to the eyepiece. |
