7. Manteniment
To ensure the best performance and longevity of your JJC 67mm CPL Filter and Magnetic Adapter Kit, follow these maintenance guidelines:

- Neteja de l'adaptador: Wipe the magnetic adapter with a soft, dry cloth to remove dust or fingerprints. Avoid using harsh chemicals.
- Emmagatzematge: When not in use, store the filter and adapter in the included storage pouch to protect them from dust and scratches.

8. Solució De Problemes
- Vignetting with Wide-Angle Lens: If you experience dark corners (vignetting) when using the wide-angle lens, ensure the adapter is correctly positioned and that the front ring is extended for larger iPhone models. Using the kit without a phone case is also recommended to minimize this effect.
- Adapter Not Sticking Securely: Ensure your iPhone's back surface is clean and dry. If using a MagSafe-compatible case, verify its magnetic strength. For best results, use the adapter directly on the iPhone without a case.
- Filter Not Threading Properly: Check for any debris in the filter threads on both the CPL filter and the adapter. Ensure the filter is aligned correctly before attempting to thread it.
