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. You can cancel the calibration by pressing the ‘exit’
keypad button on the T4.
