Basically just go through all of the settings, your going to need the manual that came with it. You need it to be on F for film which will be the first of the settings and when you go through all of the settings towards the end there is a thing that says off, thats all it should say, if there are any numbers in that field then yes it will be shutting off after that many seconds. As long as you go through the manual you should be good.
