The software will set up the ventilator to receive all button presses and control
wheel turns. The test asks the user to press each of the buttons and turn the con-
trol wheel one full turn in both directions. Each time a button is pressed the number
next to the button is reverse-highlighted. If the button is pressed and the number
next to the button does not reverse highlight the test for that button failed. If all of
the buttons are pressed and all of the numbers next to the buttons are reverse-
highlighted the button press test passes. The control wheel turn test works the
same way. The user is prompted to turn the control wheel clockwise and counter-
clockwise one full turn (16 clicks). When the control wheel is turned (one full turn
in either direction) and the control wheel is working, the test passes. If the control
wheel is not working, the test times-out in about 10 seconds and the test fails.
