3. Setup and Installation
3.1 Important: Pre-Installation Waterproof Test
Before installing your iPhone into the case, it is crucial to perform a waterproof test to ensure the case is sealed correctly and free from damage. Failure to do so may result in water damage to your device.
- Open the Case: Carefully separate the front and back pieces of the case.
- Insert Tissue: Place a piece of dry tissue paper inside the empty case.
- Seal the Case: Close the case securely, ensuring all edges are properly sealed and all port plugs are firmly in place.
- Submerge: Submerge the sealed case in water for at least 30 minutes. Ensure it is fully immersed.
- Inspect: Remove the case from the water, dry the exterior thoroughly, and then open it. Check the tissue paper for any signs of moisture.
- Result: If the tissue paper is completely dry, the case is waterproof and ready for use. If the tissue is wet, do not use the case with your phone. Contact customer support for assistance.

- Inspection: Periodically inspect the case for any signs of wear, tear, or damage, especially around the seals and port plugs. Replace the case if any damage is found to ensure continued protection.

6. Troubleshooting
6.1 Screen Unresponsiveness
If you experience reduced screen touch sensitivity:
- Ensure your phone screen and the case's built-in screen protector are clean and free of dust, smudges, or air bubbles.
- Remove and re-install the case, ensuring proper alignment and a snug fit without any trapped air.
- Verify that no other screen protector is installed on your iPhone, as this can interfere with touch sensitivity.
6.2 Muffled Sound
If sound appears muffled during calls or media playback:
- Check if the speaker and microphone ports on the case are clean and free from debris.
- Ensure the case is properly sealed, but also that the sound membranes are not obstructed.
- Test the phone's sound without the case to determine if the issue is related to the case or the phone itself.
6.3 Difficulty with Buttons
If the volume or power buttons are difficult to press or unresponsive:
- Ensure the phone is correctly seated within the case and the case is fully closed.
- Remove and re-install the case, paying attention to the alignment of the buttons.
