6. Maintenance
- Cleaning: Use a soft, dry cloth to clean the camera body. For the lens, use a specialized lens cleaning cloth and solution to avoid scratches.
- Waterproof Case: After using the waterproof case in saltwater, rinse it thoroughly with fresh water and let it air dry. Check the O-ring seal regularly for any damage or debris.
- Storage: Store the camera in a cool, dry place away from direct sunlight and extreme temperatures. Remove the memory card if storing for extended periods.
- Battery Care: For optimal battery life, avoid fully discharging the battery frequently. Charge the camera periodically if not used for a long time.
7. Troubleshooting
- Camera not turning on:
- Ensure the battery is charged. Connect to a power source and try again. If the issue persists, try a different charging cable or adapter.
- Cannot connect to WiFi:
- Make sure the camera's WiFi is enabled. Check your phone's WiFi settings to ensure it's connected to the camera's network. Restart both the camera and your phone. Verify you have the correct app and it's up to date.
- Recording issues (e.g., freezing, poor quality):
- Check if the memory card is properly inserted and has sufficient free space. Ensure the memory card is a high-speed card (Class 10 or higher recommended for 4K). Format the memory card (this will erase all data). Ensure the camera's firmware is up to date.
- Water leakage with waterproof case:
- Before each use, perform a dry test of the waterproof case without the camera inside. Inspect the O-ring seal for any dirt, hair, or damage. Ensure the case is properly closed and latched.
8. User Tips
- Versatile Mounting: Experiment with the various mounts and the magnetic feature to find the best perspective for your activity, whether it's on a helmet, bike, or even a pet harness.
- Extended Recording: Utilize the 'record while filling' feature by connecting the camera to a power bank for longer recording sessions, especially during extended outdoor adventures.
- Quick Sharing: Take advantage of the built-in WiFi and mobile app to quickly review, download, and share your footage with friends and family.
- Optimal Storage: For 4K recording, always use a high-speed TF card (U3 or V30 recommended) to ensure smooth video capture and prevent data corruption.
