After my previous experiment with the emergency stop button messed up things (see http://youtu.be/b29_IsqSx5s)
I decided to move to another location to have a second try. This time it worked by turning the Emergency Stop Button clockwise, and the button popped back.
In addition, I went to yet another location that has a different charger. It had a connection error and I could not reset it the same way. I had to make a call, so that the operator could reset it remotely.
