When I turn off my HP-2, I want it off. Uniden, however gives me some choices to keep it running. I don't want anything to keep running. After I get the admonition about running the battery down, I have to push the "ALL OFF" button. Ever since I bought it, I've never done anything but push that button when I shut it down. Is there any way to just turn it off using the top-mounted button only?
