Hi josie,
I had the same prob with my oven.  It's very simple, just press 'minute minder' and 'cooking period' bottons together and set the correct time of the day by using '+' or '-' bottons.  Once time is set release the bottons simultaneously.  The auto sign will disappear and the oven will start working.  Good luck
