Having troubles with your microphone?

  • Make sure the connections are tightened.
  • Ensure that the microphone pins on the radio are making a connection with the microphone plug.  If need be, you can very gently spread the pins with a small flathead screwdriver.
  • Make sure your CB mic is plugged in securely. Check for breaks or damage to the plug and cord. Check the pins in the radio for damage as well.
  • Be sure you are pressing the CB microphone button all the way in.
  • If it is a power mic or echo mic, make sure there is a battery in it!
