10.)Check the Gain rotary as follows:
a.) When turning the rotary in a clockwise direction, each time you hear a click, right arrows are
displayed in the Test Screen.
b.) When turning in a counter-clockwise direction, each time you hear a click, left arrows are
displayed in the Test Screen.
Note: When performing this step, make sure that a minimum of 32 clicks are heard when turning
the Gain rotary in both the clockwise and counter-clockwise directions to ensure that a
complete check is performed.
11.)Check the On/Off button.
a.) Press the button once; make sure the button is shown as depressed in the Test Screen.
b.) Release the button; make sure the button is no longer showing as depressed in the Test
Screen.
12.)Check the Lights Control (Backlights and Active Lights), as follows:
a.) trackball to the Active Lights button (under Lights Control) and press Set. Make sure that all
the corresponding LEDs are activated (illuminated green - Patient, CW, Application, etc.).
alternatively, check each one (one-by-one) individually.
b.) trackball to the Backlights button (under Lights Control) and press Set. Make sure that all the
extended keyboard backlighting is correctly illuminated.
13.)Trackball to the Battery Light button (top right of Test Screen) and press Set. Make sure that all the
corresponding LEDs is activated (illuminates green).
14.)Trackball to the Ext DC Light button (top right of Test Screen) and press Set. Make sure that all the
corresponding LEDs is activated (illuminates green).
15) Perform the Trackball Test, as follows:
a.) Move the trackball; the position of the trackball cursor on the screen is reflected by a change
in the displayed X and Y coordinate values.
Note:when the trackball cursor is positioned at the extreme top left of the screen:
X = 0 and Y = 0.
b.) As you move the trackball cursor, make sure the coordinate values increase/decrease in small
steps, without jumping more than two or three digits. If for example, the values increment by
steps of 10, this indicates that the trackball operation is faulty (possibly the trackball requires
cleaning, or replacement).
16) When done with all the above tests, trackball to the OK
button and press Set.
