After cleaning your trackle with soap and water, simply place it in its white storage box in the morning. Make sure there is sufficient air circulation so that the sensor can dry completely. 

The sensor should sit loosely in the box. Simply turn it slightly until you find the position where it slides easily into the holder.

PS: You can also close the storage box tightly if you want to transport the trackle safely, for example. To do this, turn the lid of the box slightly. The oval shape holds it firmly in place on the holder.
