I have a R20 that I programmed using ARC20 software from Butel. I wasn't happy with the way I had configured the bands so I changed them in the software. Before I uploaded the new config, I wanted to reset the scanner back to its factory settings, so I followed the instructions in the manual to do so. Now I can't switch to the TV band! I'm following the instructions in the manual but it's as though the scanner has forgotten it can do that! HELP!! What have I done wrong?
