NOTE:
Selectors 6 and 7 take effect only in the V.34 mode.
l
Selector 3: Dialing during document reading into the temporary memory in in-memory
message transmission
If this selector is set to "0," the machine waits for document reading into the memory to
complete and then starts dialing. This enables the machine to list the total number of pages
in the header of the facsimile message.
l
Selectors 4 and 5: No. of CNG cycles to be detected (when the line is connected via the
external
telephone except in the external TAD mode)
The machine 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.
l
Selectors 6 and 7: No. of CNG cycles to be detected (when the line is connected via the
external telephone in the external TAD mode)
The machine 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.
