Key Pad Problem

When I tried to set my alarm a few minures ago I pushed the far right button on top for nightime. I barely touched it and it started running between all the top settings buttons in a red light, back and forth. My S-N-L said the batteries needed to be changed. I changed them, and now NOTHING lights up in red while pushing the buttons to set the alarm. But it DOES still beep. Whats wrong and how do I fix it?
