h) Setting the volume
• The playback volume at the indoor unit can be set with the controller (9).
• The playback volume at the outdoor unit can be set with the dial switch (22) (turn to the left counter-
clockwise = volume down, turn to the right clockwise = volume up).
• The dial switch (23) can be used to set the microphone sensitivity and thus indirectly the volume on the
indoor unit (turn to the left counter-clockwise = reduce sensitivity, turn to the right clockwise = increase
sensitivity).
9. Troubleshooting
No picture, no sound
• Check the voltage/power supply (plug-in mains adapter) and the correct wiring of the outdoor and indoor
unit.
Door opener does not work
• Check the correct wiring of the door opener at the outdoor unit.
• The video-door intercom may control two door openers.
Note that the door opener connected to the screw terminals “D/O” is supplied with voltage/power di-
rectly (12 V, max. 1 A) if you push the button “
” (3).
The screw terminals “GATE” in contrast are potential-free. Only an internal relay is switched here (for
contact resilience, see chapter “Technical data"). If a door opener is to be actuated at the screw termi-
nals “GATE", you need an additional external voltage/power supply for the door opener.
When pushing the door opener, the display will go out for a few seconds.
• This is normal.
Flickering image on the indoor unit display
• This is caused, e.g. by counter-light or mirroring objects in the area of the outdoor unit's camera. Align
the camera in the outdoor unit differently if necessary.
Image too light or too dark, bad colours
• Adjust the brightness, contrast and colours in the setting menu of the indoor unit, see chapter 8. f).
