released.
o Move Venetian blind: Long press on sensor area.
o Stop or adjust Venetian blind: Short press on sensor area.
o Call up light scene: Short press on sensor area.
o Save light scene: Long press on sensor area.
o Set value, e.g. brightness or temperature setpoint: Short press on sensor area.
Cleaning the surface
o Clean the glass surface with a soft cloth. If needed, moisten the cleaning cloth.
i Do not use sharp objects for cleaning.
i Do not use sharp cleaning agents, acids or organic solvents.
i Keep moisture from penetrating into the device.

6.2 Troubleshooting
The programming LED flashes green, the device has no function.
The device has not been programmed.
Load the application software into the device.
When operated, functions are only triggered after a delay or not trigged at all.
The device adjusts the detection characteristics regularly. Long actuation of one or more sensor
areas – e.g. for cleaning or during installation – may cause the detection system to become less
sensitive.
The detection characteristics will automatically readjust to normal conditions after a short
time without operation.
Only ever press one sensor area.
