There is radio frequency signal, but no audio signal	The transmitter microphone is not connected or the receiver squelch is too deep
	Sound guidance circuit malfunction
	Setting silent mode
Audio signal background noise is too large	Transmit modulation frequency deviation is too small, receive output electrical Level is low, Or there is an interference signal
Audio signal distortion	Transmitter modulation frequency deviation is too large, receiver output electrical Level is too large
The use distance is short, the signal is unstable	The transmitter setting power is low, and the receiver squelch is too deep. Improper setting of receiver antenna and strong battery interference around.
