Observe radio frequency (RF) and audio frequency (AF) signals in level display, if the interference is greater, the channel should be switched to avoid interference points, can also increase the squelch level to enhance the anti-interference ability. 5. Then turn on the transmitter power, and after pairing the channel well, the level meter should display the radio frequency (RF) signal, adjust the receiver volume to the appropriate level and speak to microphone, then the audio (AF) signal of the receiver level would change according to the volume under normal condition.
