Fax Signal Receive
Your fax will automatically begin reception if you hear a soft fax tone
after answering a call on your fax or an extension phone. If you use a
computer fax modem to send documents on the same line, you must
turn this function off in order to prevent your fax from mistakenly
attempting to receive documents from the computer fax modem.
