Resetting the device to factory settings

1. Remove the device from the wall bracket by sliding it down carefully and slowly.

It is not necessary to remove the batteries.
2. Press the now visible button and keep it pressed for at least another 10 seconds. The LED will light up continuously during this period (if the LED does not light up, the batteries are dead and must be replaced).
3. After around 10 seconds, the LED will flash five times. Release the button.
4. The device has now been reset and can be integrated again via the software using the search mode.
5. If the device symbol remains greyed out after the device has been integrated, press the reset button again to complete the process.
