BASIC FUNCTIONS OF THE VIDEO DOOR ENTRY UNIT
2.1 SWITCHING ON THE MONITOR
When there is a door entry call, the monitor of the main IS switches on and the other devices
ring (if enabled for the door entry call). If the answer is from the other video door entry telephone,
the speaker and video connection is automatically transferred.
When the main IS monitor is on press the key of the other IS, without lifting the
receiver, to transfer the image to its monitor.
To switch both monitors on at the same time connect an extra power supply item 336010 to
the video Distributor.
