    • C
      Charles AndrewsSep 10, 2025
      If the alarm on your 3M Laboratory Equipment continues to sound even after the unit has been turned off, it indicates that the independent backup safety system has been activated or the over-temperature screw is loose. Unplug the unit and make sure the over-temperature screw is completely tightened. If the screw is missing, turn the unit off and unplug it.
