First of all, here is a direct link to the ONLINE USER"S MANUAL for a similar model (9.31):

This will open a new web browser page automatically for you and allow you to view the information at the website indicated and the contents of the Owner's Manual.
You may need ADOBE READER installed on your computer to read PDF documents.
You can download this free at WWW.ADOBE.COM if necessary.
Click on the DOWNLOAD ADOBE READER button on right side of the ADOBE home page when you get there.
If your treadmill is similar enough to the one in the manual, then there are multiple safety features incorporated into the machine. See page 9 and 10 of the ONLINE USER'S MANUAL for detailed instructions on their operation.
Acccording to the manual, TO RESUME RUNNING after the safety switch trips do the following:
Reattach the magnetic safety key to the display console.
Straddle the running belt.
Press QUICKSTART or the SPEED UP ARROW.
If required, enter the SAFETY CODE (which is 1234 unless previously changed by owner).
The belt should begin moving slowly again, so just step back on carefully while holding handles.
See page 50 of the Online User's Manual for more details about the SAFETY CODE to unlock the belt. As stated, the default Safety Code from the factory is 1 2 3 4.

Error 22 means the drive motor is diconnected. you will hear the fan and other parts make noise but check the red and black anderson connection between the main circuit board and motor.
