Selectors 1 through 4: Min. and max. OFF time length of calling signal (Ci)
If the equipment detects the OFF state of calling signal (Ci) for the time length which is
above the value set by selectors 1 and 2 and less the value set by selectors 3 and 4, it inter-
prets the Ci signal as OFF.
●
Selectors 5 and 6: Detecting time setting
These selectors set the time length required to make the equipment acknowledge itself to be
called. That is, if the equipment 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.
●
Selector 7: Delay
Setting this selector to "0" allows the equipment to insert a 900 ms WAIT after
acknowledgement of the call until the equipment turns on the CML relay to start receiving
operation.
