I just finished the install of a new Ku FTA system, and have been scanning channels and getting things set up. I was having trouble with the NBC muxes on SES 3, so I decided to try nudging the dish E/W by going into the USALS menu on the Amiko receiver. After finding that didn't help, I exited the menu but noticed it said "Saving Data" upon exit. Did I just overwrite the USALS position, or are those protected? Also, curious as to what "Go to Reference" in that menu means. Thanks!
