Have a look at the face of your bus. You will see the result of your cranking efforts.
The digits need to be adjusted individually on each roll sign. Use [F5] to [F7] to focus each digit band, from the left to the right. The aim is to set line 76. This is the bus line that stops at the hospital and at the farm and interconnects them in Grundorf. If a line has only two digits, as in this case, the last band remains on an empty field.
Please begin with the left digit line number 76. Note: Per digits roll band there are two empty fields and you will have to set the second one. Crank by using the [Page Up] and [Page Down].
