FUNCTION

As soon as a visitor rings the doorbell by pressing on the doorbell
button, the image will appear instantly on the monitor in the house.
This way you can see who is at the door before you decide to open it
(or pretend you're not at home). To speak to the visitor, you simply
press the monitor button. If you have also installed an electric door
opener, you can open the door by pressing on the door-open button.
(Only works if you have an image on the monitor)
If you wish to look outside without anyone having rung the doorbell,
press the monitor button. You cannot be heard outside when you do
this.
If you wish those outside to hear you, press the intercom button.
You can switch off the monitor's bell with the mute button. The
on/mute button then changes from red to blue. Pressing the mute
button again reconnects the bell. And the blue colour changes back
to red.
