NOTE: Selectors 5 through 7 are not applicable in those countries where no busy tone detection is supported, e.g., U.S.A. l Selectors 1 through 3: 1st dial tone detection 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) without detection of a dial tone when a line is connected to the PSTN. l 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 remote 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.

NOTE:
Selectors 5 through 7 are not applicable in those countries where no busy tone detection is
supported, e.g., U.S.A.
Selectors 1 through 3:
1st dial tone detection
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) without
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 remote 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.
