Hello,
I replaced the intercom in the apartment and the object of purchase was a digital uniphone.
However, I have a problem: when connecting red to plus, green to minus and setting the jumpers to "other", the opening works, rings, but you can not hear anything in the handset or in the control panel.
On the other hand, when we set green to plus, red to minus, you can hear through the handset - but when you hold down the button, you won't hear any sound from me in the control panel.
Anyone know what's going on?
