If I might not get back to it, I turn it off and unplug. I'm afraid I'll forget and it'll end up plugged in during a storm or surge. I do use surge protectors. If it's just for a bathroom break, etc, I don't shut it off, but I put the 820 in "Eco" mode with that button to the right of the line at the bottom of the screen. Supposed to conserve the light, I guess.
