I just received my 436hp the other day and I am having issues trying to program the darn thing. I used the sentinel software and set up my 5 favorites. I set preferences for the fav's with alerts etc. I transferred the info using the cable to the scanner/ But when I try to scan with it, I get the" nothing to scan" message. Only way to scan is to enable the nationwide database which of course has way more on it than I want to listen to. Any step by step instructions would be appreciated. Thanks.
