disassembled for servicing.
• Only use the Microcal (DOS) program or the Touchware Control
Panel (Windows) to calibrate the touch screen.

Calibration Procedure
The calibration program looks at where your finger is when you lift it
off the screen, not where you touch it. Therefore, calibrate the screen as
follows:
1. Touch the screen near the calibration target.
2. Keep your finger on the screen and slide it to the center of the
target.
3. Hold your finger firmly on the target for two seconds, then lift it off
quickly.
4. Verify that the calibration was set accurately before making a
service call. Perform the calibration again if necessary.
