2. Important Safety Information
- Pre-Dive Test: Before each use, especially for diving, always perform a waterproof test without the camera inside. Submerge the empty case in water for at least 30 minutes to check for any leaks.
- Inspect Seals: Regularly inspect the rubber sealing gasket for any dirt, hair, cracks, or damage. Even a small particle can compromise the waterproof seal.
- Avoid Extreme Temperatures: Do not expose the case to extreme temperatures, as this can affect the integrity of the seals and materials.
- Handle with Care: Avoid dropping or subjecting the case to strong impacts, as this may cause damage and compromise its protective capabilities.
- Proper Closure: Ensure the case is properly closed and latched before submerging it in water.
- Rinse After Saltwater Use: After using in saltwater, rinse the case thoroughly with fresh water and allow it to air dry.
3. Setup and Installation

4. Operation
4.1 Button Functionality
The housing case features external buttons that align with the GoPro Hero 9's controls. These buttons allow you to operate the camera's functions (e.g., power on/off, mode change, shutter) without removing it from the case. Press the buttons firmly but gently to activate the corresponding camera controls.
4.2 Diving Depth
The TELESIN GP-WTP-901 housing case is rated for a maximum diving depth of 45 meters (approximately 147 feet). Do not exceed this depth to prevent potential damage to the camera or housing.
5. Maintenance and Care
5.1 Cleaning
- After each use, especially in saltwater, rinse the entire housing case with fresh water.
- Use a soft, clean cloth to gently wipe the case dry. Avoid abrasive materials that could scratch the lens port or case body.
- For stubborn dirt, use a mild soap solution and rinse thoroughly.
5.2 Storage
- Store the housing case in a cool, dry place away from direct sunlight.
- It is recommended to store the case with the latch open to relieve pressure on the rubber gasket, prolonging its lifespan.
5.3 Gasket Inspection
- Periodically remove and inspect the rubber sealing gasket for any signs of wear, cracks, or deformation.
- Ensure the gasket is clean and free of any foreign particles before reinserting it.
- If the gasket shows signs of damage, replace it with an official TELESIN replacement gasket to maintain waterproof integrity.
6. Troubleshooting
- Leakage: If the case leaks during a pre-dive test, re-check the sealing gasket for proper seating, cleanliness, and damage. Ensure the latch is fully secured.
- Fogging: Fogging inside the case is often caused by temperature differences and humidity. Use anti-fog inserts (desiccants) inside the case to absorb moisture. Ensure the camera and case are dry before sealing.
- Buttons Sticking: If buttons feel stiff or stick, rinse them thoroughly with fresh water. Ensure no sand or debris is lodged around the button mechanisms.
- Poor Image Quality: Ensure the lens port on the housing is clean and free of scratches. Check that the GoPro Hero 9 lens itself is clean.
