WARNING
• Only use your projector on a solid, level surface. If the projector falls to the ground, you can be injured and the projector severely damaged.
• Do not use the projector where temperatures vary greatly. The projector must be used at temperatures between 41˚F (5˚C) and 95˚F (35˚C).
• Do not expose the projector to moisture, dust, or smoke. This will harm the screen image.
• Ensure that you have adequate ventilation around your projector so
heat can dissipate. Do not cover the vents on the bottom or the side
of the projector.
