A touch screen calibration page may be evoked from the user interface default operating screen:
Perform a diagonal action or "swipe" from the top right area of the LCD to the bottom left area:

NOTE: Both the targets must be tapped correctly for the calibration to take effect. This is done to prevent the calibration
from changing dramatically from the default.
Calibration will be ignored if the user does
not tap in the general area of the target
(correct area is the size of the target icon)
If the user does not tap in the general area
of the first target, then calibration will not
be saved no matter what happens in the
second target
Count down timer; calibration will be
ignored when time runs out

CAUTION: Do not use a pen, pencil or
other sharp object to tap on the CXC

may void the warranty.
