Calibrating the Touch Screen
1. With all the components connected and switched on (as listed in previous section), press the
calibration button on the back of the touch screen.
The program moves the pointer to a position at the top left of the screen
2. Touch and hold your finger at position indicated by the pointer until until you hear a long beep.
3. The pointer moves to three further positions in a sequence—touch each point in turn until you hear
the beep.
This completes the calibration procedure. Test the calibration by touch the screen at different
positions and check that the cursor follows you finger.
