Selectors 6 and 7: Dial tone detection in PABX
l
These selectors activate or deactivate the dial tone detection function which detects a dial tone
when a line is connected to the PABX.
Setting both 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.
Other setting combinations deactivate the dial tone detection function so that the equipment starts
dialing after the specified WAIT (3.5, 5.0, or 7.0 sec.) without detection of a dial tone when a line is
connected.
l Selector 8: "R" key function
This selector determines whether or not the 1st dial tone detection function (specified by selectors
1 through 3 of WSW05) is added to the R key.
If this selector is set to "0," pressing the R key automatically activates the 1st dial tone detection
function when the PABX and the automatic calling are selected by using the function switch. If
you press the R key and a dial number in succession, the equipment will automatically carry out
the 1st dial tone detection function following the original transfer function as shown below.
