•Do not expose the Data projector to moisture, dust, or smoke. This will harm the screen image.
•Ensure that you have adequate ventilation around your Data projector to allow heat dissipation. Do not cover the vents on the bottom or the side of the projector.
Positioning the unit
The projected image becomes larger as the distance between the unit and screen increases. The minimum image size is about 24 inches (0.61
m)diagonally at a distance of about 1.2 m (3 feet) and the maximum size is about 300 inches (7.6 m) at a distance of 12.0 m (39.37 feet) from the screen. Use the following information when you fix the position of the unit.
