Other devices
If desired, you can use an answering
machine or an extension telephone
on the same line as your fax. The
answering machine or extension
telephone can be connected directly
to the TEL. SET socket on your fax
(note that this socket is not available
in some countries), or to another wall
socket.
Connecting an answering machine
to the fax or a wall socket will allow
you to receive both voice and fax
messages on the same line while
you are out. For details on using
this feature, see Chapter 6.
You can use an extension phone
connected to the fax or a wall
socket to make and receive calls
like any normal telephone. For
details on receiving faxes from the
extension phone, see Chapter 3.
