5. Maintenance
To ensure the longevity and appearance of your phone case, follow these maintenance guidelines:
- Cleaning: Wipe the case regularly with a soft, damp cloth. For stubborn dirt, a mild soap solution can be used. Avoid harsh chemicals or abrasive cleaners, as these may damage the material or finish.
- Storage: When not in use, store the case in a clean, dry place away from direct sunlight and extreme temperatures.
- Inspection: Periodically inspect the case for any signs of wear or damage, especially around the corners and the ring holder mechanism, to ensure continued protection.
6. Troubleshooting
If you encounter any issues with your phone case, please refer to the following common solutions:
- Case Does Not Fit Properly: Ensure you have the correct model case for your koobee SL004T phone. Gently re-align the phone and case, applying even pressure to seat it correctly. Verify that no foreign objects are obstructing the fit.
- Ring Holder Stiffness: If the ring holder feels stiff, gently rotate it a few times to loosen the mechanism. Avoid forcing it beyond its intended range of motion.
- Magnetic Attachment Issues: Ensure your magnetic car mount is clean and free of debris. Verify that the magnetic car mount itself is functioning correctly. The case's magnetic function relies on direct contact with a strong magnetic surface.
