OBU Manual
Version 3.0 August 27, 2020 21
The OBU display shows all booked toll services. If the OBU is not personalized for a toll service, then the name
of the toll service will not be listed. In the example above the toll services Bulgaria (BGria), Portugal (PTvve) and
Hungary (HUgo) are not booked and therefore not listed.
Change number of trailer axles
The driver must always check and/or update the number of trailer axles when entering a new toll domain,
especially in case of coupling or uncoupling the trailer
Example change number of trailer axles
Here the number of trailer axles is changed from zero (no trailer) to three. After updating the value, press right
key for “ok” to save your change. Leave the menu by pressing two times the left key to come back to the
start display.
You can also use this menu to only check the currently set number of axles. If you do not want to change them,
leave the menu by pressing the left key without pressing “ok”. If you press left key without saving and the
number of axles has been modified, an information screen will be displayed for some seconds: “Value not
changed” and the old value is kept.
Change current weight for toll service Germany (DEbag)
For DEbag the user always needs to check and/or update the value to the current gross train weight before en-
tering Germany especially
when a trailer was coupled or uncoupled. The current gross train weight (GTW) is
the maximum permissible combined weight of the tractor and the currently attached trailer.
