Why doesn't the green light turn on when charging my 3M Headsets?
If the green light on the charger never comes on, the battery may be defective and needs to be replaced.
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.
What to do if there is no vehicle alert tone in all headsets of my 3M Intercom System?
If there is no vehicle alert tone in all headsets, here are a few things you can check: 1. Ensure the external vehicle detector is receiving power by plugging it into a power outlet or replacing the detector fuse. 2. Try resetting the vehicle detector by removing power for a few seconds. 3. Adjust the alert tone volume on the base station. 4. Verify that the system is not in Always On order taking mode by changing the talking mode.
Why won't all 3M Intercom System headsets go into standby when the vehicle leaves the menu sign?
If all headsets do not go into Standby (silence) when the vehicle leaves the menu sign, consider these possible causes: * If using a pulse (air switch) type of vehicle detector, press the Page switch to silence the menu microphone. * If a loop is used, check for and remove any large metal objects near the loop in the driveway. * Reset the loop detector by unplugging it from the AC outlet and plugging it back in. * The system could be in Always On order taking mode, so change the talking mode.
