You can monitor the conversation of the substation at this time and the substation will not know your monitoring. The volume can be adjusted with volume control button.
4) Recording function
You can real-time record the conversations of each substation with a recorder (having microphone input port) or LB-PT2002 digital recording monitor system.
5) Cutting off the conversation of substation:
Press the router button (MODE key) to select the substation you will cut off. Pressing the router button (MODE key) once will increase one call. The LED of selected substation will lighten. Press and hold the time setup button (UP/RET key) for 2 second when the LED is lightening to cut off the conversation of the selected substation. If the time disappears from the digital tube, the conversation has been cut off. If you will cut off other conversations, repeat above procedures.
6) Restoring the conversation having been cut off
Press the router button (MODE key) to select the substation you will restore. No time display indicates that this substation is in cutting off status. Press and hold the time setup button (UP/RET key) for 2 second, the time will appear on the digital tube and the conversation has been restored. If you will restore other conversations, repeat above procedures.
 
Note:
Insert the connector on the extension (WBT-10G) to the interface on the extension on the master station to make up of 20-call master station (WBT-20)…
