- Attach the Lens: Screw the Apexel 20-40X telephoto lens onto the threaded opening of the universal phone clip. Turn clockwise until securely fastened.

5. Maintenance
Proper care will extend the life and performance of your lens:
- Cleaning the Lens: Use the provided cleaning cloth or a soft, lint-free microfiber cloth to gently wipe the lens surfaces. For stubborn smudges, use a small amount of lens cleaning solution applied to the cloth, not directly to the lens.
- Storage: When not in use, store the lens in its EVA carrying bag to protect it from dust, scratches, and impacts. Keep it in a dry, cool place.
- Avoid Extreme Conditions: Do not expose the lens to extreme temperatures, humidity, or direct sunlight for prolonged periods.
- Handle with Care: Avoid dropping the lens or subjecting it to strong impacts, as this can damage the optical elements.
6. Troubleshooting
If you encounter issues, refer to the following common problems and solutions:
- Blurry Images:
- Ensure the focus ring is properly adjusted for your subject.
- Verify the lens is clean and free of smudges.
- Use the tripod for stability, especially at higher zoom levels.

- The lens may not be perfectly aligned with your phone's main camera. Re-align carefully.
- Slightly zoom in on your phone's screen to crop out the dark edges.

- Ensure the phone clip is tightened firmly but not excessively.
- Verify your phone model is compatible with the universal clip design.
