Slots and vents in the projector provide ventilation. Never block or cover these
openings. This ensures reliable operation of the projector and prevents overheating.
◊ Do not place the projector over a radiator or heat register. The projector should
not be placed in an enclosure unless proper ventilation is provided.
◊ Do not “poke” objects into the ventilation openings of the projector. They may
touch dangerous voltages or short-out components resulting in a fire or shock
hazard. Do not spill liquids of any kind into the projector. Should an accidental
spill occur, immediately unplug the projector and have it serviced by a qualified
service technician.
If any of the following conditions exist, immediately unplug the projector from the
power outlet and ask a qualified service technician to look at it.
◊ The power cord has been damaged.
◊ The internal cooling fans do not start operating when the projector is first turned
on. (NOTE: Fans in the lamp ballast will start once lamp is ignited.)
◊ Liquid has been spilled into the projector.
◊ The projector has been exposed to excessive moisture.
◊ The projector is not operating normally or its performance has significantly
deteriorated in a short period of time.
◊ The projector has been dropped or the shipping case (if applicable) has been badly
damaged.
Do not attempt to service the projector yourself. All
servicing must be performed by manufacturer accredited
service technicians.
Use replacement parts that are manufacturer-approved
only. Use of any other part other than the ones specified
by the manufacturer can result in fire, electric shock or
risk of personal injury and irreparable equipment
damage.
The projector itself requires little or no cleaning if it is operated in an environmentally
controlled environment. However, if you find that the projector may need some
cleaning based on its performance call a qualified service technician.
The table below provides cleaning instruction for those items on the projector that
may require periodic cleaning.
Always power down and unplug the projector before any
cleaning or servicing.
