To prevent your LEUCHTIE Mini from switching on during shipping, one of the batteries has been inserted upside down as a transport lock. For the first activation this battery must be turned around:
To open the LEUCHTIE, separate the tube at the side of the size sticker from the battery pack with a slight twisting movement, taking care not to use excessive force.
Remove the battery from the end of the tube and turn it around.
Place the battery into the light tube with the negative pole ahead.
Push the battery pack back into the end of the tube. Take care that the spring is centred in the battery pack.
Press tube and battery pack firmly together as far as it can go. There must be no gap between the battery pack and the tube.
