I have a 2yr old A2550 which just recently started showing only demo information. The belt would not come on nor would the key change the system to manual mode. I used information mode just to see if changing the modes might help but after setting it to info mode the console blacked out. Now whenever I turn on the treadmill the lights come on for a second then the console screen goes blank. Please help.
When in Demo Mode, the console will go through a repeating lighting pattern. This
mode will only become active when the treadmill is plugged in, the main on/off switch
is turned on, and the safety key is not inserted into the console.
The Demo Mode was added to attract attention to the treadmill while it is on display. By
default, all treadmills with Demo Mode will come with it turned on. Demo Mode can be
turned off at any time.
Method #1 to switch from the Demo Mode:Press and hold the STOP button while inserting the safety key to enter the user
Look in the Calories window. When Demo Mode is active, the letter 'd' will
Press the SPEED DOWN button to toggle the mode on and off.
Once the mode is set as desired, remove the safety key. Read More At : NordicTrack Treadmill, A2550...
