4. Setup
Follow these steps to set up your Svbony SV28 spotting scope:
- Attach the Tripod:
Unfold the legs of the tabletop tripod. Locate the tripod mounting screw on the top of the tripod head. Align the screw with the threaded hole on the bottom of the spotting scope. Rotate the scope clockwise to securely attach it to the tripod. Ensure it is firmly tightened but do not overtighten. - Adjust Tripod Angle:
The included tabletop tripod allows for 360-degree rotation and angle adjustments between 160-180 degrees. Loosen the adjustment knob on the tripod to set your desired viewing angle, then tighten to secure. - Attach Phone Adapter (Optional):
If you wish to use your smartphone for photography, attach the universal phone adapter to the eyepiece. Adjust the adapter to securely hold your phone, ensuring the phone's camera lens is aligned with the spotting scope's eyepiece. The adapter supports phone widths from 52-100mm.

5. Operating Instructions
To use your Svbony SV28 spotting scope effectively, follow these operational guidelines:
- Remove Covers:
Remove the objective lens cover and the eyepiece cover before use. - Adjust Eyecup:
The eyepiece features a fold-down eyecup. If you wear eyeglasses, fold down the eyecup for a full field of view. If you do not wear eyeglasses, keep the eyecup extended for comfortable viewing. - Adjust Magnification:
Rotate the zoom ring on the eyepiece to adjust the magnification from 25x to 75x. Start with the lowest magnification (25x) to locate your target, then gradually increase to your desired level. - Focusing:
Once your target is in view, slowly rotate the focus knob until the image appears sharp and clear. Fine-tune the focus for maximum clarity. - Extend Sunshade:
Pull out the extendable sunshade located around the objective lens to reduce glare and protect the lens from rain or dust.

6. Maintenance
Proper care and maintenance will ensure the longevity and performance of your spotting scope:
- Cleaning Lenses:
Use the provided lens cleaning cloth or a soft, lint-free cloth to gently wipe the objective and eyepiece lenses. For stubborn smudges, use a small amount of lens cleaning fluid specifically designed for optical surfaces. Avoid using abrasive materials or excessive force, as this can scratch the lens coatings. - Cleaning Body:
Wipe the body of the spotting scope with a soft, damp cloth. Do not use harsh chemicals or solvents. - Storage:
When not in use, store the spotting scope in its EVA carrying case to protect it from dust, dirt, and impacts. Keep it in a cool, dry place away from direct sunlight and extreme temperatures. - Waterproof and Fogproof:
The SV28 spotting scope is IP65 rated, meaning it is protected against dust ingress and low-pressure water jets from any direction. It is also fogproof. While it can withstand light rain, avoid submerging it in water.

7. Troubleshooting
If you encounter issues with your spotting scope, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Image is blurry or out of focus. | Incorrect focus adjustment. | Rotate the focus knob slowly until the image becomes sharp. Ensure you are focusing on the correct distance. |
| Dark edges or vignetting in the view. | Eyecup not properly adjusted or eye not centered. | Adjust the fold-down eyecup (down for eyeglasses, up for bare eye). Position your eye centrally and at the correct distance from the eyepiece. |
| Image is dim or unclear. | Lenses are dirty or sunshade is not extended. | Clean the objective and eyepiece lenses with the provided cloth. Extend the sunshade to reduce glare. Ensure sufficient ambient light. |
| Difficulty attaching phone adapter. | Phone not within supported width range or improper alignment. | Ensure your phone's width is between 52-100mm. Carefully align your phone's camera lens with the spotting scope's eyepiece before tightening the adapter. |
| Tripod feels unstable. | Tripod legs not fully extended or screw not tightened. | Ensure tripod legs are fully extended and stable on a flat surface. Tighten the mounting screw connecting the scope to the tripod. For outdoor use, a full-size camera tripod is recommended for better stability. |
