In the affected devices, Magnet Rundown Unit (MRU) may not be connected to the magnet. If the MRU is disconnected, the MRU will not function as expected and will not quench the magnet when the button is pressed. In emergency situations, a disconnected MRU could delay removal of a ferrous object from the magnet, potentially resulting in life-threatening injuries. The MRU must be connected to the magnet at all times.
