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 detection
starting point in the case of automatic line disconnection due to no voice
signal received
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.
