2.4.3 Calibration of the touch Screen
On the initial boot-up of the PDT, the stylus
calibration screen (Labeled Align Screen)
opens. Use the stylus to press and hold
briefly on the center of each target as it
moves around the screen.
If necessary, adjust the backlight on the PDT
to make the screen readable. (See below
2.4.4. Adjust the brightness).
When you feel the touch screen function is
poor or the operation does not match the
exact location it should be, please
recalibrate the screen by using the stylus to
tap the Start > Settings > Control Panel >
Stylus, to open the “Calibration” to
recalibrate again.
