Advanced Touchscreen Calibration
The following directions will help you calibrate your touchscreen more accurately.
1. Enter calibrate mode. When the first dot appears, intentionally touch the screen about 1”
away from the dot, diagonally, towards the center of the screen (repeat this procedure
for the second calibration dot; see Figures 1a and 1b). You are now in TEST SCREEN
mode. As you test the screen, you should notice that the crosshair is considerably out of
calibration. By completing this step, you have shown that the machine is accepting
calibration input.
