Warning

network by keeping the power cord connected to
your machine when you connect it to a telephone
line. Similarly, you can protect yourself when you
want to move your machine by disconnecting the
telephone line first and then the power cord.
If you are sharing one phone line with an
external telephone, connect it as shown
