YES 1. NO • Selectors 1 and 2: Application of DC wetting pulse and overvoltage limiter These selectors take effect only when the UK version of the facsimile equipment is set up for the British Telecom's caller ID service or its equivalent. Selector 2 takes effect only when selector 1 is set to "1." • Selectors 4 and 5: No. of CNG cycles to be detected The equipment interprets a CNG as an effective signal if it detects a CNG signal by the number of cycles specified by these selectors when the line is connected via the external telephone except in the external TAD mode. • Selectors 6 and 7: No. of CNG cycles to be detected (For those models not equipped with a built-in TAD) The equipment interprets a CNG as an effective signal if it detects a CNG signal by the number of cycles specified by these selectors when the line is connected via the external telephone in the external TAD mode or via the facsimile equipment in F/T mode. • Selector 8: FAX reception after the time-out of pseudo ring backtones in F/T mode If this selector is set to "0," the equipment enters the facsimile receive mode after issuing pseudo ring backtones. If it is set to "1," the equipment disconnects the line after issuing pseudo ring backtones.
