• Selectors 1 and 5: CNG detection when sharing a modular wall socket with a telephone
These selectors determine whether or not the machine detects a CNG signal when a line is
connected to a telephone sharing a modular wall socket with the machine. Upon detection
of CNG signals by the number of cycles specified by these selectors, the machine interprets
CNG as an effective signal and then starts FAX reception.
