In case of intercommunicating calls to different fl ats, in case of calls coming from outdoor sets and in case of
call at fl oor, all the user monitors always ring. It is also necessary to consider the following information:
♦
0 and 1 extensions, at call reception, ring immediately; 2 and 3 extensions ring following;
♦
if the case of a call comes from a videophone outdoor station, the monitor whose bracket is set as 0
extension, turns on; monitors connected to the other brackets set with the same user address, but with
other extensions, are able to turn on entering the 0 extension monitor, by pressing the “_” button (“video
transfer” function); the transfer is the cause of the power down of the monitor, which was previously turn
on.
