NOTE: Selectors 5 through 7 are not applicable in those countries where no busy tone detec-
tion is supported, e.g., U.S.A.
Selectors 1 through 3:
These selectors activate or deactivate the 1st dial tone detection function which detects the
1st dial tone issued from the PSTN when a line is connected to the PSTN.
Setting all of these selectors to "1" activates the dial tone detection function so that the
equipment starts dialing upon detection of a dial tone when a line is connected. (However, in
those countries which support no dial tone detection function, e.g., in the U.S.A., setting
these selectors to "1" makes the equipment start dialing after a WAIT of 3.5 seconds.) For
the detecting conditions of the 1st dial tone, refer to WSW07 and WSW08.
Other setting combinations deactivate the dial tone detection function so that the equipment
starts dialing after the specified WAIT (3.5, 7.0, 10.5, 14.0, 17.5, 21.0, or 24.5 seconds) with-
out detection of a dial tone when a line is connected to the PSTN.
Selector 4: Max. pause time allowable for remote ID code detection
This selector sets the maximum pause time allowable for detecting the second digit of a re-
mote ID code after detection of the first digit in remote reception.
If selector 4 is set to "0" (2 seconds), for instance, only a remote ID code whose second digit
is detected within 2 seconds after detection of the first digit will become effective so as to
activate the remote function.
