Connect the ground terminal of the AC inlet of this unit to the ground terminal provided in the building using an optional three-core power supply cord. • Always use the liquid crystal projector in a horizontal position, if possible. If you operate the liquid crystal projector with its lens upwards, its lens downwards or to the side, the heat generated inside the projector may build up and cause malfunctions or damages. Be especially careful to never block the ventilation holes. • Do not install the LCD projector in a smoky surrounding, since smoke residue may be accumulating on critical parts (i.e. LCD panel, lens, etc.).
