Operation
CALIBRATE TOUCHSCREEN
This button runs a routine that allows you to calibrate the touchscreen. Since it normally should not be necessary to calibrate the touchscreen, this routine is included as a precaution only.
Warning: Do not attempt to calibrate the touchscreen with your fingertip. Proper calibration requires a stylus or other fine tip. Do not use metal objects such as ball point pens or screwdrivers that can damage the surface of the touchscreen.
Press the Calibrate button to continue.
Follow the directions on the display to complete the calibration process.
