Calibrate Screen

The Calibrate Screen option allows you to calibrate the color touchscreen. This process
makes fine adjustments for optimal display. Use a SOFT fine tip stylus pen or the eraser
end of a pencil.
If your touch screen is still slow to respond, it needs to be recalibrated again. It may help
to use the eraser end of a pencil to calibrate the screen.
