Plug it in YouTube or the internet and learn what it does.I won't have any challenges with the "fucked up" part, I can handle that. I might even get a gold star.
I still have not figured out the camera I inherited, it's got so many functions that I'm always wondering how to use it properly. It's not a real fancy camera but has more going on than my other one. Would be nice to understand it better because it has many many settings for various conditions.
