Make sure you complete the calibration procedure without powering off the monitor mid-way. If the
monitor is powered off after the first point is touched, the touch panel will be deactivated until the
touch calibration is performed again.
If the touchscreen is accidentally mis-calibrated by selecting the wrong spot, you must use another
input device to re-enter calibration mode, for instance, a mouse connected to the PS/2 interface. If
you have the support tool, you can select
which will allow you to access the calibration menu again via the touchscreen.
