Calibrating the Screen (Windows CE Terminals Only)
The first time you start your PDT 7500 terminal (and whenever the
terminal is cold-booted), the calibration screen displays. This
section describes how to calibrate your terminal so the cursor on the
touch screen aligns with the tip of your stylus.
Note: If your terminal came loaded with another software ap-
plication, the calibration screen may not display.
To calibrate your PDT 7500 terminal:
1. If necessary, adjust the contrast on the PDT 7500 so the screen
is clear and readable. See “Controlling the Screen Contrast”
on page 8 for instructions.
2. As the screen instructs, carefully press and briefly hold the sty-
lus on the center of each target. Repeat as the target moves
around the screen.
3. Tap the screen when prompted to accept new calibration.
