A manual fax is a fax that is transmitted over a previously established telephone connection, usually when you have dialed the call yourself, perhaps had a voice conversation and then wish to send a fax over the connection. The modem does not have to dial the number, only go off hook and start the transmission or reception. The default selections show here are recommended. Note that some modems work better with manual fax if you leave the telephone receiver off hook during transmission or reception, others work better if you hang up the receiver immediately when you hear the modem begin to emit fax tones.
