2.2 Buttons and other controls on the screen
When you are using AZ291MA, you usually tap buttons on the touch screen.
You only need to confirm selections or changes in AZ291MA if the application needs to restart, it
needs to perform a major reconfiguration, or you are about to lose some of your data or settings.
Otherwise, AZ291MA saves your selections and applies the new settings without confirmation as
soon as you use the controls.
