Volume setting/Melody selection
Press the "Volume"/"melody forward/backward" button until you hear the
required volume/melody.
You can change the volume at any time and this is independent of the
corresponding transmitter. The last selected volume is automatically saved.
You can still replay different bell tones by pressing "Melody forward/backward".
This does not effect the saved bell tone when coding between transmitter and
receiver.
Installation
Choose a suitable location for the chime and motion detector. Check the selected
location for wiring before drilling any holes.
Tip: Test the desired function before ultimately installing the device at the place
of installation you chose.
Place the motion detector at a suitable location. The non-slip coating is included
in the packaging and provides for a secure grip on the floor or use the assembly
fixture with the enclosed screws. The recommended installation height is
2 - 2.2m, to cover a maximum detection zone.
Note:
• The detection zone depends on the selected location. Wall-mounted or
ceiling installation should be favoured.
• Avoid undesired sources of heat, cold and movement, e.g. fan heaters, direct
sunlight, refrigerators or fans, in the detection zone, to prevent false alarms.
• Avoid the motion detector lens from being shielded, so as not to limit the
detection zone, e.g. by plants or furniture.
• Select the location in a manner, which allows the detection of movement based
on the crossing of several detection zones. The detection of movement is less
precise in the direction of the motion detector than it is crosswise to it.
• Avoid installation opposite windows. In this case, air flow or motion in front of
the window can trigger false alarms.
