• Q: Why the Sound is very weak
  A: The sound not only depends on the mic volume but also depends on the FM receiver volume. So please add the volume of the microphone with pressing “+” once by once(Do NOT hold on ). And also please volume up FM receiver. If no sound after adjusting the volume, the wireless may be disconnected and please re-pair it via adjusting transmitter and receiver to the same frequency
