When I first configured my tuner (digital ATSC, USA), I specified a zip code and Digital Terrestrial Lineup to get program guide information for OTA channels.
I now think that I will get better results using the major zip code of the location of the broadcast antennas, but I cannot find any way to change the profile, and the delete button is always greyed out for the first profile - even if you added others.
How do I change the zip code ?
Thanks.
