I have a 3900 as a third receiver. I installed it in my work shop which is about 2 miles from my house. I have an xtra dish with a
Dish Pro LNB. I cannot get anything and it keeps telling me no switch detected. It was working, but I was only getting 110.
Still cannot get anything. On the peak screen should I be on Dish 500. If so how do I move down to check the box. It will only move back and forth from the Zip to the Sat #. I have hooked it up directly to the 119 LNB. On the screen it continues to tell me Installed device unkown.
