      Only use the two middle wires on the connector. Make sure you use an RJ11-connector.

          As a last resort you can put the defective unit in a machine and reset the unit in SP5-801. Did you also set the jumper on the FCU to ON?

            The "using handset" message for me has usually meant the machine is plugged into a bad phone line. Or if the fax cable is plugged it into a surge suppressor or line conditioner they could be bad. Get a telephone handset and plug it into where the cable from the machine plugs into. If you don't hear a clean dial tone from the handset, it is most likely the phone company's fault, or the line conditioner or surge suppressor might have has failed.
