coordinates the positioning of the pen 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. You should not need to calibrate again unless the
projector or image is moved, or the image is resized.
Note: You can
start Auto Calibration by pressing the User button on the remote control or by pressing
the Menu button on the remote
control as described here.
