What is Remote Activation?

If you answer a call that is a fax message, you can use the Remote Activation Code
to make your MFC take over the call. If your MFC answers a telephone call that is for
you, you can use the Remote Deactivation Code (#51) to pick up the call at an extension
phone. You must use a touch tone phone.

Connecting an External or Extension Telephone

You may connect an external telephone to your MFC, as shown below. Use
the "EXT." jack on your machine.
Alternatively, you may wish to use this "EXT." jack to connect a telephone
answering device (TAD). An extension phone is a telephone that is plugged
into a separate wall jack on the same line.
