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, unplug the projector from the power
outlet and refer service to qualified service personnel.
• The power cord has been damaged.
• The internal cooling fans do not come on when the projector is first turned on.
• Liquid has been spilled into the projector.
• The projector has been exposed to excessive moisture.
• The projector does not operate normally.
• The projector has been dropped or the case has been damaged.
• Projector performance has deteriorated.
WARNING
Do not attempt to service the projector yourself. All
servicing must be performed by CHRISTIE qualified
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.
