Full instructions for calibration are given on the screen when the calibration display
appears (see Figure 1-3).
H A small circle with a dot is highlighted in succession in each of three corners.
View the screen directly on to avoid parallax errors and use a small blunt
pointed tool, such as a pencil eraser tip, to produce the best accuracy for the
calibration. Touch the screen directly over the first dot. The dot in the next
corner then lights. Touch the second dot, and then touch the third dot to finish
the calibration.

H After calibration, the screen will display the Paint screen. You can test areas of
the screen for activity by touching the screen at various points. The touch point
will become highlighted. The Clear soft key on the touch screen erases the
highlighted areas of the Paint screen.
