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 intercom
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.
