PREPARATIONS FOR FAX
To use the machine as a fax, the telephone line must be connected and the type of line set.
CONNECTION TO THE TELEPHONE LINE
Be sure to use the provided telephone line cord 
to connect the machine to the wall telephone 
socket. Connect the end of the line cord that 
has the core to the "LINE" socket on the 
machine. Insert the other end (the end without 
the core) into a telephone line socket.
In some countries, an adapter is required to 
connect the telephone line cable to the wall 
telephone socket, as shown in the illustration.
