I've been watching so many reviews and searching several forums, but for the life of me I can't figure out how to completely switch off my old DNA 40W device. 5 click only locks the device, so short of taking out the battery I can't get it complete off. Best I can do at the moment is to unscrew the copper/brass threaded but that hold the battery in place to completely kill it, and I don't want to always keep a screwdriver at hand. Can anyone remember how to switch these off completely please? It's a Pandora's Box specifically.
