## **Notes** 

Switching threshold adaptation: 

Only, the first teach-in procedure after switching on is permanently stored. Teach-in can be repeated cyclically. Switching output also during teach-in active. 

Once teach-in process is complete, the switching threshold can be adjusted at any time using 

- the “+” or “–” button. To make minor adjustments, press the “+” or “–” button once. To configure settings quickly, keep the “+” or “–” button pressed for longer. 

- Press both the “+” and “–” buttons together (3 seconds) to lock the device and prevent unintentional actuation. 

- Press both the “+” and “–” buttons together (6 seconds) to define the switching function (light/dark switching). Standard setting: Q = light switching. 

Teach-in (static): Setting the switching threshold without movements of label, cf. operating instruction.
