Calibrate the touchscreen to adjust the touch pressure (sensitivity) needed to activate functions on the touchscreen.
Lower percentage = less pressure, more sensitive
Higher percentage = more pressure, less sensitive.
To calibrate the screen:
From the Main Menu, tap Tools.
Tap Screen Calibration.
Follow the instructions on the screen to perform the calibration. Time Remaining counts down the 15 seconds given to complete each step. A screen message informs you if the calibration succeeded or failed.
