Since the MFC is grounded through the power 
outlet, you can protect yourself from potentially 
hazardous electrical conditions on the telephone 
network by keeping the power cord connected to 
your MFC when you connect it to a telephone line. 
Similarly, you can protect yourself when you want 
to move your MFC by disconnecting the telephone 
line first and then the power cord.
