I recently had a defective H20-600 replaced with a H20-100. When it first said 'Searching for satellite", I pressed "Menu" and selected "Setup" in order to set the proper dish type. The screen went directly to the satellite signal level screen for the 101. The signal strengths were all acceptable, so I went to the next satellite. The signal levels there were all good, so I stepped through the other satellites, 99, 103, 110, and 119. Now, here's the "problem". I have the Slimline 3 (non-SWM). How did the signal levels on 110 and 119 show up as good? And I was never presented with an opportunity to select the proper dish type. I assume the new software detected the dish type. Also, I did not have an OTA antenna connected and the screen to set up my primary and secondary zip code for OTA channels never appeared. I assume that the "no antenna connected" condition was also automatically detected. Has anyone else observed this behavior on a H20-100?
