Currently, when I need to switch off my Atv and keep it, I just switch off the mains and pull the plug. I am just curious if there is a "proper" way to turn it off, and if my current actions might damage it in any way? I am doing this 1-2 times a day on average. The context is that I am a school teacher using the Atv in my classroom, so I typically keep it after lessons for security reasons and as a power-saving measure. There doesn't seem to be any sort of "off-switch" of any kind. Thanks all for your advice.
