Guidelines for Calibrating the Touch Screen (If Equipped)
The following guidelines should be observed for calibrating the touch
screen.
•
Calibration should be done at time of installation.
•
Recalibrate the touch screen when the system is installed at its final
location.
•
Recalibrate whenever the terminal is moved to a new location.
•
Recalibrate the touch screen anytime the system has been
disassembled for servicing.
•
Only use the Microcal (DOS) program or the Touchware Control
Panel (Windows) to calibrate the touch screen.
Microcal:
a. Set the video resolution. Go to the Tools menu, Video. Select
800 x 600 256 colors.
b. Go to the Tools menu, select Calibrate.
Touchware Control Panel:
a. Go to the Calibrate tab and press Calibrate.
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.
