Caution:
•Placing the projector on a carpet reduces ventilation from the fan on the bottom and might cause problems. Place a hard board or similar item under the projector to facilitate ventilation of the unit.
•Place the projector more than 8 in. from the wall to prevent blocking the intake, exhaust slots and ventilation of this projector because hot air comes out of it.
•Do not use the projector under the following circumstances, which may cause fire or electric shock.
•in a dusty or humid place
•while the projector is lying sideways or upside down.
•near a heater
•in a kitchen or oily, smoky or damp place
•in direct sunlight
•where the temperature is lower than 41° F or higher than 95° F
