WELCOME!!!!
First make sure your mast, "the thing the dish mounts on" is level. Next go to the receiver and go to the dish pointing screen. You should find a zip code input some were here depending on what type of receiver you have, there it will show you your settings, the elevation and azimuth, and if you have a oval 2 or 3 dish your tilt. Next set your elevation and use a compass to dry point your dish. Depending on how far you are from the receiver you may want someone telling you what the signal is while you fine tune the dish. Feel free to ask anything else.
