5. Safety Precautions
Failure to follow these precautions may result in water damage to your phone and void the product warranty.
- Waterproof Test: Before each use, especially the first time, perform a waterproof test without your phone inside. Submerge the empty case in water for at least 30 minutes. Inspect for any leaks. If leaks are detected, do not use the case and contact support.
- Inspect Seals: Always check the O-ring seal for any debris, hair, or damage before closing the case. A clean and intact seal is crucial for waterproofing.
- Proper Closure: Ensure the case is securely and completely latched shut. The security lock must be engaged.
- Depth Limit: Do not exceed the maximum diving depth of 40 meters (130 feet).
- Temperature: Avoid using the case in extreme temperatures that may affect the phone or case materials.
- Impact: Protect the case from drops or impacts, which could compromise its waterproof integrity.
- Button Operation: Due to water pressure, buttons may require firm pressing underwater.
- Phone Preparation: Fully charge your phone before use. Set your phone to the desired camera mode before sealing the case, as touchscreen functionality is limited underwater. Keep the camera app open.
6. Setup Instructions
6.1 Initial Waterproof Test (Mandatory)

- Submerge the empty case in a sink or bucket of water for at least 30 minutes.

7.1 Pre-Dive Phone Settings
- Camera App: Open your iPhone's camera application and select your desired mode (photo, video, etc.) before sealing the case.
- Auto-Lock: Disable auto-lock or set it to a longer duration to prevent the phone from sleeping during your dive.

- Low Power Mode: Disable Low Power Mode to ensure full camera functionality.
7.2 Underwater Operation
- Buttons: Use the physical buttons on the case to control your iPhone's camera functions (e.g., shoot, mode, power). Press firmly due to water pressure.

8. Maintenance and Storage
- Cleaning: After each use, especially in saltwater, rinse the case with fresh water. Use the provided cleaning cloth to gently wipe the lens and screen areas.
- O-ring Care: Periodically inspect the O-ring seal for cracks, tears, or deformation. Clean it gently with a soft cloth. If necessary, apply a thin layer of silicone grease (not included) to maintain its elasticity and sealing properties. Replace damaged O-rings immediately.
- Storage: Store the diving case in a cool, dry place away from direct sunlight and extreme temperatures. Keep the case slightly ajar during storage to prevent compression of the O-ring.
- Avoid Chemicals: Do not use harsh chemicals, solvents, or abrasive cleaners on the case, as they can damage the materials and seals.
9. Troubleshooting
9.1 Water Leakage
- Cause: Improperly closed latches, damaged O-ring, debris on O-ring.
- Solution: Ensure all latches are securely closed and the security lock is engaged. Inspect the O-ring for any foreign particles or damage; clean or replace if necessary. Always perform a waterproof test before use.
9.2 Buttons Not Responding
- Cause: Phone not properly aligned, excessive water pressure, phone screen locked.
- Solution: Re-open the case and ensure the phone is correctly seated. Press buttons more firmly. Ensure the phone's screen is active and the camera app is open before diving.
9.3 Fogging Inside Case
- Cause: Temperature difference between inside and outside the case, high humidity.
- Solution: Ensure the phone is dry before placing it in the case. Consider using anti-fog inserts (not included) if fogging persists in humid conditions.
