Adjusting the Angle of the Laser (Touch Unit Auto Setup)
An infrared laser in the shape of a curtain is emitted from the Touch Unit. The infrared laser reflects off your
finger when touched to the projection surface thereby detecting the finger position allowing the projector's
infrared camera to recognize the position being reflected.
Adjust the angle of the laser light coming from the Touch Unit so that the projector can correctly detect the
position of your finger.
If the laser is not emitted parallel to the screen, the projector will not detect touch operations or the position
of your finger correctly.
