Also keep these considerations in mind: ■ Make sure there is plenty of space for ventilation around and under the projector. Do not set the projector on top of loose materials that could block the vents underneath. ■ Make sure the projector is within 9.8 feet (3 m) of a grounded electrical outlet or extension cord. 16 Setting Up the Projector
