Hi Emily,   If you're in Program mode, you should just tap "Mode" and it switches to Run. If you press and hold "Mode" it should go to Preset. Are you saying that's not happening? Can you get into Setup by pressing and holding SHIFT and MODE together? If so, go into Setup, press the Up arrow to get to <Test Mode>. Is the middle line of the LCD blank, like the first image, or does it have something written in it, like the second image. If it has something written in it, what does it say?
