Q1
I installed the video/audio door phone and the external panel is giving a continuous tone, is there any problem?

No, there’s no problem. The continuous tone just appears in case the alarm function is activated. There’s a contact switch behind the second screw on the external panel. You need to fasten the second screw then the alarm tone will disappear immediately.

Our video door phone has been installed and everything works fine, except that on the indoor terminal I got a blue screen.

Most probably you’ve done a mistake during installation, please check the connections Vout and GNV on the external panel, Vin and GNV and Vout and GNV on the power supply and (for 2 or 3 family versions only on the connection box Vin, Vout, Vout1 and Vout 2) and Vin and GNV on the indoor terminal.
