When calling from the external panel the video appears on my Classe 100Xbut it doesn't sound! | Legrand België

If your Classe 100X doesn't ring durign a video door call, check that the silent mode is not active on you internal unit.

You could check from the "ringtone" menu on Classe 100X that the volume of the ringtone is high enough; if needed, increase the volume by turning the programming joystick Up.
