F/T SWITCH ACTION
Not all fax machines are capable of sending a fax tone (the CNG tone that warns the receiving fax machine that a
fax is coming). For those cases the machine may think that the call coming in is a voice call and rings to alert you of
the call (the amount of time it is going to ring is determined by the <F/T RING TIME> setting above). If you do not
answer the call, one of two things can happen:
1. If you set the <F/T SWITCH ACTION> to 'RECEIVE', the machine will switch to fax receive mode automatically at
that point and start to receive the document. If no document comes in, it disconnects the call after
approx. 40 seconds. The factory default setting is 'RECEIVE'.
2. If you set the <F/T SWITCH ACTION> to 'DISCONNECT', the machine will disconnect the phone call
immediately freeing up your phone line at this point.
