do not aim at 99W. There is nothing KU Band there and will just frustrate you.
Since your longitude is 89.8, lets use 89W as the true south satellite. Bring up IA8 in the menu. It should be in there if I remember right. Select a strong transponder
(see http://www.satelliteguys.us/showthread.php?t=85225 for the strong transponder)
Make sure the dish elevation and the motor elevation are correct. You should aim the dish pretty much straight south. The quality meter stays red until it locks on the satellite then it turns green. Set up the LNB as "Single" and 10750
