Caution:
•Placing the projector on a carpet reduces ventila- tion 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 20 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
•with high temperature, such as the closed car
•where the temperature is lower than 41° F or higher than 95° F
Important:
•Do not put stress on the lens or focus ring, as this may damage them.
•Keep your room dark while using the projector. The image cannot be seen clearly in a bright place.
