l Selectors 1 through 4: Min. and max. OFF time length of calling signal (Ci)
If the machine detects the OFF state of calling signal (Ci) for a time length which is greater
than the value set by selectors 1 and 2 and less than the value set by selectors 3 and 4, it
interprets the Ci signal as OFF.
l Selectors 5 and 6: Detecting time setting
These selectors set the time length required to make the machine acknowledge itself to be
called. That is, if the machine continuously detects calling signals with the frequency set by
selectors 1 through 4 of WSW14 during the time length set by these selectors 5 and 6, it
acknowledges the call.
