You need to reset both the Box and the Motor. Here is an alternate method using ASALS used by my friend rrob, all credits to him:

"First , figure out which satellite is due south. The longitude of your location will be your due south satellite. Then set the motor to 0 on the marks. Using a compass, figure out roughly where due south is and point the motor with satellite centered at this. Follow the instructions for the dish and motor to set the elevation of the dish and motor. I forget these numbers but there should be a calculator for it. Then use your signal meter or receiver and input the strongest transponder for your due south satellite. You can then move the dish/motor assembly left and right and up and down until you hit the due south satellite. Once you get a peaked signal there and if the motor is at 0. You should be able to find the other satellites easily with the USALS settings on the receiver.

If your due south satellite is not exactly at your longitude, find the satellite anyway. For example if your longitude is 71w and your due south is 72w, you would want to find 72w and then move the dish and motor assembly slightly to the left (as you are behind the satellite) you will know you are on when you input 72w on the usals settings and the dish will move back to the right to 72w. You can then peak the dish at the closest usals setting, as long as your pole is plumb, you will then be able to track the arc provided your dish settings are proper.

How do you key in USALS Local Lat & long??

Enter your latitude and longitude, then use the arrow key on the remote to move to a stored city, then arrow back to what you entered, and exit the menu. Return to the latitude/longitude menu and verify that your latitude
