OK. Now if all you changed on the order was the dish size, you should have the stock system which has a universal LNB.
Make sure the LNB cable is attched to the "sat in" slot on the back (might be listed as LNB in)
Turn on receiver and lets make sure everything is set up right
-press "menu"
-antenna setup
-select IA5 Ku 97W (should be on there)
-LNB type is Universal
-positioner is OFF or disable
-transponder should scroll to either "12177 V 23000" or "12152 H 22000"
-0/22k should be greyed out and auto
-switch and imput are set to "none"
now that we got the menus set, the elevation on Fortec dishes (from past experience) has been off in some cases so it may not be exactly at 36. Aim dish dead south (hopefully you can see the screen from the receiver...its easier to tune that way then having someone holler)
and SLOWLY move dish west a little bit. KU Band takes more time to think then DBS satellites (Dish & Direct). Dont worry about signal strength, its QUALITY that matters.
If you move it west and dont get anything, slowly move back east. Try raising the elevation on the dish a degree and repeat.
Another option is to use the "aim and scan" technique. Aim it around 186 azimuth and hit the "PScan" button on the remote. What that does is scans the active transponders whereever you are and will load the channels in. You may not be on 97 but with satellites at 91,93,95,99,101 etc you're bound to lock on SOMETHING. Then we can go from there on where to move the dish.
(on a side note I'm kinda shocked you got the order already)
Dont let it get to you. You'll get it soon. PM me if you have some other issues and I might be able to help solve them
