During the initial commissioning of a twin stick, the LED flashes immediately to signal the first synchronization between the twin sticks.
For all other power-up processes, the LED only flashes if the previous system partner does not answer within 20 s. In this case, communi‐
cation can also be established with a replacement twin stick.
