Belt will not move:
If you press the “Start” button, the belt does not move and you are not
getting an “Err” message on the control panel, please check the red
safety shut off key. If the red safety key is not inserted properly into the
control panel, you will hear two beeps when you press the “Start” button.
When the key is inserted in properly, you will only hear one beep and
then the belt will start moving.
