Chapter 2: Hardware Installation 2-21<br />
Guidelines for Calibrating the Touch Screen (If Equipped)<br />
The following guidelines should be observed for calibrating the touch<br />
screen.<br />
• Calibration should be done at time of installation.<br />
• <strong>Re</strong>calibrate the touch screen when the system is installed at its final<br />
location.<br />
• <strong>Re</strong>calibrate whenever the terminal is moved to a new location.<br />
• <strong>Re</strong>calibrate the touch screen anytime the system has been<br />
disassembled for servicing.<br />
• Only use the Microcal (DOS) program or the Touchware Control<br />
Panel (Windows) to calibrate the touch screen.<br />
Microcal:<br />
a. Set the video resolution. Go to the Tools menu, Video. Select<br />
800 x 600 256 colors.<br />
b. Go to the Tools menu, select Calibrate.<br />
Touchware Control Panel:<br />
a. Go to the Calibrate tab and press Calibrate.<br />
Calibration Procedure<br />
The calibration program looks at where your finger is when you lift it<br />
off the screen, not where you touch it. Therefore, calibrate the screen as<br />
follows:<br />
1. Touch the screen near the calibration target.<br />
2. Keep your finger on the screen and slide it to the center of the<br />
target.<br />
3. Hold your finger firmly on the target for two seconds, then lift it off<br />
quickly.<br />
4. Verify that the calibration was set accurately before making a<br />
service call. Perform the calibration again if necessary.
