Note:
Do not lose the touchmonitor's APR Calibration USB Drive or APR
Calibration file! It is unique to your touchmonitor, and required for
that touchmonitor to function.
If you need to connect this touchmonitor to a different computer, or if
you need to update the touch driver on your computer, you will need
this APR Calibration USB Drive again.
