Straight out of the factory, your Winegard T4 Road Trip Satellite will be preset for the DirecTV network. If you will be using any of the other available networks, here's how to make the change.
Remove the Roadtrip dome by removing the 6 screws around the base of the satellite
Around the back where the coax cables come in, you can find the dip switches that need to be set.
Set the dip switches according the the diagram for the network you will be using.
That's it! Your satellite is now tuned for your particular network and should be good to go!
