Appendix A: Touch Screen Calibration
Note: Only units with resistive touch screens need to be calibrated. PCap displays do
not require calibration.
Proper Touch Screen Methods
Before performing the calibration procedure please observe the following guidelines for
proper/improper methods of touching the screen.
• Face the monitor directly.
• Perform the calibration in the position (sitting or standing) that you normally expect
to use the touch screen.
• Touch the calibration target firmly and precisely with your fingertip. During
calibration, be careful to keep your fingernails and other fingers away from the
touch screen as you touch each target.
• The hand and calibration finger should be perpendicular (straight up) from the
touch screen during touch down and removal of the calibration finger. Keep the
other fingers closed and away from the touch screen.
• Do NOT touch the bezel with your other fingers.
