Why do I need to calibrate the system before using the pen for the first time?
Calibration coordinates the positioning of the pens with the location of your cursor. You need to calibrate only the first time you use your projector, and you do not need the pens or a computer for calibration.
Note: You should not need to calibrate again unless the projector or image is moved or the image is resized.
