Report "Hi, I bought a used norditrack elliptical 600. The console does not turn off and there is an annoying bip. None of the buttons is responding. I have to remove the batteries to make that bip stop. When I get on the elliptical it does work but nothing is responding (time, calories, carbs, everything is showing) but If i want to choose a program, nothing. Whant can I do? Thanks"
