This bus has an automatic rollsign control unit.

This eliminates the cranking for adjusting the signs. To enter a destination traditionally, set the device and press "Start". The upper numbers indicate the number of the current target range. Below you can enter the number of the new target. Right to those switches you can set the line. Press start at each part to apply the setting. The red button synchronizes the unit with the rollsign and resets the settings completely.

Please set line 76 and the destination "Nordspitze Bauernhof" by using the new unit. The association between number and destination is written down left above your work area at the sheet.
