I don't have a link, but I do have experience, what part are you looking for in the instruction manual, the skew setting? If so, and you know the skew setting of a Dish 1000 for your area, it'll be the same.
Hey...I thought only the elevation was the same as the 1000. The skew is the same as the 500; and the skew only becomes the same as the 1000 whenever you convert a 500+ to a 1000+, right?
