It appears my 2 HP-1's are Phase 1 only, so the update reminded me of time to update. I also have a bc536 HP and it is a Phase 2 scanner yet after the update to data base, it does not stop on any of the channels except detention and it is to weak to understand. I have read as much "do this, do that" as I could find but have no luck, is it possible I do not have system at Phase 2, should it find it automatically, is there some secret setting, is the data base correct or is there an error. Last question, one can not alter or add to database or can they, as I have found no such info on the web either. The sentinel software for this scanner is completely different than that of my HP-1, of course I had to find that out last year after first buying a bc536 HP. If you don't know, you have to learn/find. thanks if helpful
