Calibrate Touchscreen Function
If the touchscreen does not seem to accurately register your taps on the screen, you can use the Calibrate Touchscreen function to recalibrate it. The Calibrate Touchscreen function presents a series of
targets that you tap. If there is a difference between the location you tap and the target’s actual coordinates, the difference is saved and the offset is used to interpret subsequent screen taps.
The function can be performed at any time.
See Figures 6-17 and 6-18.
