Please start the engine of your motorhome; a few seconds later, the satellite unit should retract by itself due to a safety shutdown.
If this was not successful, reset the satellite unit by disconnecting the vehicle from the power supply. To do this, please switch off the operating panel above the conversion door, disconnect the 230 V connector (if plugged in) from the feed and then set the battery cut-off switch on the transformer/rectifier (EBL) to OFF. After approx. 2-3 minutes, reverse the whole process and try to retract the satellite unit via the operating unit.
If the satellite unit still does not retract, you must manually remove the articulated arm including the parabolic reflector using the two screws on the jointed arm and store it safely in the rear garage of the vehicle and then visit the nearest Bürstner dealer who can analyse and rectify the fault on site.
