Touch screen calibration

The touch screen is calibrated at the factory and rarely needs modification. However, if actual touch
locations do not appear to correspond with responding objects on the display, field adjustment is
available. Ensure SYS_fn Enable is set to YES in the System Menu. To access the field adjustable touch
screen calibration dialog, press and hold both the SYS and F1 key for longer than 2 seconds and a dialog
similar to Figure 5.3 should appear. Thereafter, use a plastic tip stylus and follow the dialog instructions.
For best results in screen calibration, use a stylus with a plastic tip. When the crosshair appears,
touch the center of the crosshair as exactly as possible and release. A small "+" should appear
and will move closer to the center of the crosshair. Once it has done so and disappeared again,
repeat the process until "+" appears in the center of the crosshair. Then move on to the next
step.
