cord should always be in use while on your treadmill.

bottom of the display as shown. This magnetic key 
is an emergency shut off and will abruptly stop the 
walking belt should you fall down while using the 
treadmill. Removing this magnetic key while not in 
use will prevent children or unwanted users from 
operating the treadmill.

the treadmill without this cord in place. To deactivate
