Too Many Ambient
Sounds Are Picked Up| 1. Make sure the microphone is as close as possible to the subject
2. Adjust the camera volume to 5 positions
3. RX volume adjustment
4. Wear Windproof Sponge
Noisy or distortion, Including electric current, Noise floor, Boom, etc.| Signal is disturbed
1. Try to record indoors, there is less radio frequency interference indoors.
2. Keep the transmitter and receiver away from conductive objects such as metal and water.
3. Overhead telephone lines, fluorescent lights, and metal fences will all cause interference to the wireless microphone.
