It is not required to open the complete control box to access the BS buttons on the PCB and read
out the seven-segment display(s).
To access you can remove the service window cover (see figure). Now you can open the inspection
door of the control box cover (see figure). You can see the 3 BS buttons and the 3 seven-segment
displays and DIP switches.
