New Mini Mac Help Needed

I just got a new mini mac and am stuck at the log in screen (my name or guest user account) with sleep, shut down or re-start options; however, it wont recognize my apple wireless mouse or keyboard. Therefore, I can do NOTHING (cant get to any system preferences or anything beyond this screen) and have already tried a re-start. Please help. I have also already 1) make sure they are disconnected from old mac (yes they do work on other imac), 2) made sure the switch is turned to green and that they are charged.

Help please!
