Check if there is any interference (other transmitters, high-power
cables, Wi-Fi, etc.) that may be interrupting good communication
between the remote control and the control unit. If interference is
present, the manoeuvring tool will not function and the green LED
on the remote control will flash.
Generally speaking, all error messages are reset automatically

The caravan battery could be almost flat when the drive rollers are
engaged. Check the current drop on the caravan battery display.
If this falls to well below 10 Volt immediately, charge or replace

The caravan battery could be overloaded. Check your charger. Try
to discharge the battery a little with an additional consumer (light

control unit.
Poor connections or corroded battery connections can cause inter-
