entering data or selecting a test, simply by touching a command button on the touch screen. An
audible beep will alert you to successful button activation.
Note: While using the touch screen, the HFA II-

button you select. Be careful not to pound or press too hard against the touch screen. A light touch
works best.
If you have difficulty activating the touch screen, consi

touch screen are found in “Additional Setup,” on page 2-30, as well as in “Touch Screen
Calibration,” on page 15-11.
Pop-Up Windows
Frequently, when you select an option from a screen, a smaller scr

over the original screen (Figure 2.3). This additional screen is called a “pop-up” window. It may
provide information or require data input. In either case, only command choices (buttons) appearing
within the pop-up window ar
e active at that time. You cannot select an icon button when a pop-up
window is open.
