The touch panel is calibrated (also called compensated) at the factory. The factory
calibration is used by the system until it is periodically updated. VeriFone strongly
recommends that the touch panel be calibrated daily during a period of inactivity.
During calibration, the unit must not be touched. VeriFone also recommends that
the display backlight be turned off during calibration. Use the
setDspBrightness() function to turn off the backlight. Use the
touchCompNSave() function to perform the daily touch panel calibration.
