I recently moved and now the Nordic Track elypitical CX 938 - Model # 30621.0 machine makes a beep beep sound, when I try to use it. I put new batteries in and it works for a second and everything flashes and it goes off. It makes a beep beep sound every time you start to pedal on it. I recently lost my job and I can not afford to pay another $900 for another elyptical machine. Can you pretty please help me?
