- Selectors 2 through 4: Detection time length of PABX dial tone, required for starting
Upon detection of the PABX dial tone for the time length set by these selectors, the
machine starts dialing. These selectors are effective only when both selectors 6 and 7 are
set to "1" (Detection).
- Selectors 6 and 7: Dial tone detection in PABX*
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
machine 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 machine
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.
