Avoid contact with liquids and exposure to damp
Do not use the projector near water (sinks, tubs and so on); do not place objects
containing liquids on or near the projector and do not expose it to rain, humidity,
drops of water or sprays; do not use water or liquid detergent to clean it.
Place the projector on a stable surface
Place the projector on a stable surface or use a suitable ceiling mounting bracket.
Never place the projector on its side or rear, on the lens or top panel or rear.
Do not allow the projector to overheat
To prevent overheating, allow a free space of at least 0.20 m (5 in) on the rear, on the
top, and on the right and left sides of the projector. Do not obstruct the ventilation
slots. Do not place the projector near heat sources such as heaters, radiators or other
devices (including amplifiers) that generate heat. Do not place the projector in an area
where there is insufficient space (shelving units, bookshelves and so on) and in
general avoid placing it in poorly ventilated areas as this may prevent sufficient
cooling and significantly reduce light-source life.
Take special care regarding movement of the lens
Do not place objects in the slots on the side of the lens and also ensure that vertical
lens movements are not impeded by external objects.
Do not hold the projector by its lens.
