Why is my 3M Intercom System not communicating and all headsets have a flashing green LED?

The 3M Intercom System might not be communicating, and all headsets might have a flashing green LED due to several reasons. First, ensure that the power transformer is correctly plugged into both the wall outlet and the base station. If the LCD display remains off, verify the power at the wall outlet. If the headsets are not registered, register them. If the issue persists, the base station might be defective, and you should call for authorized service.
