Why can't I switch on my SILENO Pro, max or free when I start it for the first time?

In the state of delivery, the robotic lawnmower is in a so-called "deep sleep".
To deactivate "Deep Sleep", please place the robotic lawnmower once in the charging station with power.
Note: The boundary wires or guide wires do not need to be connected for this.
You can then activate your robotic lawnmower via the on/off button.
