Selectors 1 through 3: 1st dial tone detection time length
Upon detection of the 1st dial tone for the time length set by these selectors, the machine
starts dialing.
This setting is effective only when selectors 1 through 3 of WSW05 are set to "1,1,1."
l
Selectors 4 and 5: Time-out length for 1st and 2nd dial tone detection
These selectors set the time-out length for the 1st and 2nd dial tone detection so that the
machine waits dial tone input for the specified time length and disconnects itself from the line
when no dial tone is inputted.
