1. Console could be in demo mode.
Please press and hold the up and down arrows until all the lights on the console come on. From there a menu screen will come up and the third or fourth option is Demo mode. Select "off" and press enter.
2. Your machine could be too close to a strong wireless signal.
The machine is likely picking up a wireless signal inside your home or business because of the availability of the wireless heart rate monitor. If you can not move the machine far enough away from the wireless signal, simply unplug your machine after each use.
