General operation
• When a programmed bell push button on the external video unit is pressed, a ringtone is
heard both at the external video unit and at the programmed internal unit, and the image
of the visitor is displayed on the screen of the internal unit. At the same time, the green
LED on the internal unit switches on and stays lit until the receiver is put down again. If a
non-programmed or deleted bell push button is pressed, you will hear a single, short beep
tone and the light relay in the bus control will be activated.
• If the call at the external video unit is not answered, the connection will automatically be
interrupted after 30 seconds, and the green LED on the internal unit will switch off. If the
call is answered within 30 seconds, a speech connection will be established. The speech
connection will be interrupted two minutes after the call is answered or automatically if
the conversation is terminated. At the same time, the green LED on the internal unit will
switch off.
