Operating Range
The PointRacer uses scanning technology to detect the distance and projected image area. The
scanning angle and distance are illustrated in the following figure.
Screen
For best results, point the interactive pen directly at the screen without line of sight interference.
Adjusting the Display
On-screen interference is caused when the image is blocked and shadows are created in the project-
ed image. The PointRacer function requires direct scanning of the image. To avoid interference,
adjust the projected image as suggested in the following.
