WARNING
•Carrying the unit
Always carry the unit in the carrying case. Ensure that the power cable and any other cables connecting to video sources are disconnected before moving the unit. When moving the unit or when it is not in use, cover the lens with the lens cap.
•Only use the unit on a solid flat level surface. If the unit falls to the ground, you may be injured and the unit may severely be damaged.
•Do not use the unit where temperatures vary greatly. The unit must be used at temperatures between 5° C (41° F) and 35° C (95° F).
•Do not expose the unit to moisture, dust, or smoke. This will harm the screen image.
•Ensure that you have adequate ventilation around the unit to allow heat dissipation. Do not cover the vents on the bottom or the side of the unit.
Positioning the unit
The projected image becomes larger as the distance between the unit and screen increases. The minimum image size is about 25 inches diagonally at a distance of about 1.2 m (approx. 3.9 feet) and the maximum size is approx. 300 inches at a distance of 12.3 m (approx. 40.4 feet) from the screen. Use the following information when you fix the position of the unit.
