We have had our Proform 680 Crosstrainer unplugged for a few months and we are wanting to use it again. At this time when we plug it in we get nothing on the screen except for FF on the bottom right of the screen. I have hit the reset button on the bottom by the power cord, but that doesn't do anything. The model number is 831.24646.0

Thank you for any help.
