Note:
Selectors 1 through 5 are applicable to models equipped with built-in TADs.
- Selectors 1 through 3: Erasing time length of ICM tone recorded preceding the tone
If the machine has disconnected the line after detection of disconnection tone in ICM
recording, it erases tone recorded preceding the tone detection starting point for the time
length set by these selectors.
- Selectors 4 and 5: No. of CNG cycles to be detected (when the line is connected via the
external telephone in the external TAD mode or via the machine in
F/T 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 or via the machine in F/T mode.
- Selectors 6 and 7: Number of DTMF tone signals for inhibiting the detection of CNG
during external TAD operation
If the machine receives this specified number of DTMF tone signals during external TAD
operation, it will not detect CNG afterwards.
If these selectors are set to "1, 1," the CNG detection will not be inhibited.
