I have not installed an AU9 before, but if it's anything like a
Dish 1000 which has 3 LNB's, you just need to read the directions on the
installation guide for the dish. For Dish 1000, they told me to point the dish at one satellite (119) and peak the signal for that one. If you have set the skew correctly, the other two satellites will be picked up by the other two LNBs once the receiver sends the signal to switch LNBs and tune into the other satellites.
