Preparation and setup
58
Do not place the control unit loosely in the cab. The control unit for the
electrical potentiometer must be mounted on a suitable retainer in the cab of
the towing vehicle.
Loose objects in the cab can fall down and block control elements, such as
pedals. This can result in a loss of control over the tractor/trailer combination
and thus give rise to dangerous situations (in road traffic).
