Texas Instruments MATRIX 3000, DW30 user manual

Section 4: Maintenance

•The projector is equipped with a three-wire plug having a third grounding pin. This is a safety feature – if you are unable to insert the plug into an outlet contact an electrician to have the outlet replaced. Do not defeat the safety purpose of this grounding-type plug.

Ventilation f 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.

Servicing f 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 turn on when the projector is first powered up.

•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.

WARNING

Do not attempt to service the projector yourself. All servicing must be performed by CHRISTIE 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.

WARNING

Never service the projector while it is still plugged in. There are exposed voltages that could cause severe physical injuries and possibly death. Always unplug the projector and wait two minutes to allow the capacitors on the power supply to discharge before removing the projector’s covers.
