My intercom buzzer (Comelit Genius -2 wired) isn't ringing no more. I can still open the door, but there's no ring tone! I am posting the pictures of the intercom. Can anyone help me please.
Thanks OwainDIYer for your reply. I have checked connection at the call tone volume switch and its fine nothing is broken. When we dial the intercom from the front door it display an error message as "user is not available"
Problem with receiver switch on handset ? Showing off hook / error , if it's tone gerated call via the handset and the receiver switch is open it won't ring , check the blue/ switch
