For best results:
•
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.
5. Repeat this procedure for the second target.

registers immediately when you touch the screen.
