Setup
1. Attaching the Neck Strap
- Thread the ends of the padded shoulder strap through the strap loops on each side of the binoculars.
- Adjust the strap length for comfortable carrying around your neck or over your shoulder.
2. Adjusting Eyecups
The binoculars feature twist-up eyecups for comfortable viewing, whether you wear eyeglasses or not.
- For Eyeglass Wearers: Twist the eyecups down completely to ensure your eyes are close enough to the lenses.
- For Non-Eyeglass Wearers: Twist the eyecups up until they are fully extended. This provides optimal eye relief.

3. Focusing the Binoculars
Proper focusing ensures a sharp and clear image.
- 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. Rotate the 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 adjust focus for different distances. The diopter setting should remain constant unless your vision changes significantly.
4. Attaching Phone Adapter and Tripod
The universal phone adapter and tripod allow for stable photo and video capture through the binoculars.
- Screw the tripod adapter onto the central hinge of the binoculars.
- Attach the tabletop tripod to the tripod adapter.
- Secure your smartphone into the universal phone adapter.
- Carefully align your phone's camera lens with one of the binocular eyepieces. Adjust for optimal view.

Operating Instructions
1. General Usage
Hold the binoculars firmly with both hands. Bring them to your eyes and adjust the interpupillary distance (the distance between the two eyepiece barrels) until you see a single, circular field of view. Then, use the central focus wheel to achieve a sharp image.

Maintenance

- For stubborn dirt, use a lens cleaning fluid specifically designed for optics.
- Clean the body of the binoculars with a soft, damp cloth.
2. Storage
- Store binoculars in the provided carrying case when not in use.
- Keep in a cool, dry place away from direct sunlight and extreme temperatures.
- Ensure lens caps are on to protect the optics from dust and scratches.

Troubleshooting
- Blurry Image: Re-adjust the central focus wheel and the diopter setting on the right eyepiece. Ensure eyecups are correctly positioned for your vision.
- Dark Edges/Incomplete View: Adjust the interpupillary distance by moving the two barrels closer or further apart until you see a single, clear circle.
- Difficulty with Phone Adapter: Ensure your phone's camera lens is perfectly aligned with the binocular eyepiece. The 360° swivel on the tripod allows for fine adjustments.
