Bindings with…

I just got a K2 Formula and a NS Evo and the shop mounted the bindings on the board for me. I was just wondering how to take the bindings off the board now because the footbed is covering the screws and I have no idea how to remove the footbed/take the bindings off. Also, when are you supposed to take your bindings off and what side effects happen if you keep you bindings on your board permanetly
