Why do I need to calibrate the system before using the pen for the first time?

• Calibration coordinates the positioning of the pens or finger (BrightLink 1430Wi) with the location of your cursor. You only need to calibrate 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.
