The Buddy System allows an authorized, trained Supervisor or Safety Officer to quickly adjust the "Warning" and "Shutdown" (red-Zone) distances to suit the application and the size of the CM. However, the Supervisor will need a 'Little-Genius' unit and the correct security access code to do this.

The Little-Genius wireless trouble shooting unit lets anyone check the complete system without getting close to the CM.
