8. After 30-seconds, since oxygen is not hooked-up, the
system senses that the oxygen concentration is inadequate.
The audible alarm sounds and the red system light goes on.
9. Move the red set-point needle to 10%. As the red needle
passes the black needle, the audible alarm stops. Both the
alarm and oxygen system lights go out.
