You first need to set up your Tuners.
Are you just using 1 cable, from your motorized dish, to one Tuner, and the one from your fixed dish to the other Tuner?
Which image have you got loaded, the original one, from vuplus, or another, like Black Hole?
If you go into the menu, Setup, System Searching, Tuner Configuration, and select the Tuner connected to your fixed dish, e.g. Tuner A, set it to Simple, Mode = Single, and Satellite Astra 2, 28.2E.
If Tuner B is your Motorized, then set that up as Simple, Mode = positioner, and enter your Latitude, and Longitude, if using a Usals motor. Positve Longitude readings = East, Negative = West. You can find your position at dishpointer.com, just enter your postcode, zoom in on the map, and move the icon to your house.
