Using the unit
Connecting to a PBX
Connecting to a PBX allows you to answer door calls from any telephone. See page
14 for wiring information.
Please use only a Panasonic PBX. See page 8 for the PBX model list that is
compatible and other optional hardware.
Important:
• At first, set “PBX SELECT” to “ON” in the menu settings. (Page 40)
Note:
• If you answer a call from the door station with a PBX extension, the camera
image from the door station will be displayed at the monitor station. If the monitor
station user tries to answer the call, a beep will sound. The display will turn off
when the conversation has ended or when the conversation has continued for
more than 3 minutes.
• If you answer a call from the door station with the monitor station, the call will
continue to ring at the PBX for about 15 to 30 seconds. If the PBX user answers
the call while the call is still ringing, the door station user, the monitor station user,
and the PBX user can speak together.
