User Tips
- Audio Quality: For better audio quality in noisy environments, consider using external audio recording equipment as the camera's built-in microphone may pick up ambient noise and does not support an expandable microphone.
- Waterproof Seal: Always double-check that the waterproof case is securely closed and the seal is clean before any underwater use to prevent water damage.
- Memory Management: Regularly transfer your videos and photos to a computer or cloud storage to free up space on your MicroSD card and prevent data loss.
- Battery Life: Carry a portable power bank or spare battery if you plan extended shooting sessions, as the 90-minute working time may be insufficient for all-day use.
