Calibration

To use Easy Interactive Function, you need to make sure you perform
calibration to align the pen position on the screen and the mouse position
on the projection screen with the Easy Interactive Pen.
There are two calibration modes: Calibrate (Normal) and Calibrate
(Advanced).
Specify 25 points with Calibrate (Normal), and 49 points with Calibrate
(Advanced).
Make sure you perform calibration the first time you use Easy Interactive
Function. After that, you only need to perform calibration if the usage
environment changes, for example if the connected computer is changed or
the projection area is changed.
