My Quinton Treadmill display shows all 8s and will not operate. What is wrong?

If your Quinton treadmill powers up and displays all 8s but will not operate, the Limited Access Switch has been activated.  The treadmill will not operate unless the magnetic key is in its place on the display or the Limited Access Switch has been deactivated.

How to Deactivate the Limited Access Switch:

• Press POWER to turn off the treadmill
• At the same time, press and hold the +, -, and POWER keys.  Continue holding all keys until the 8s on the display disappear.  Release the keys.

The Limited Access Switch will remain deactivated until the magnetic key is put in its place on the display.
