Important Information
Power Supply
1.The projector is designed to operate on a power supply of 100- 120 or
2.Handle the power cable carefully and avoid excessive bending. A damaged cord can cause electric shock or fire.
3.If the projector is not to be used for an extended period of time, disconnect the plug from the power outlet.
4.Do not touch the power plug with wet hand. Doing so can cause electrical shock or fire.
5.Do not touch the power plug during a thunder storm. Doing so can cause electrical shock or fire.
Cleaning
1.Unplug the projector before cleaning.
2.Clean the cabinet periodically with a damp cloth. If heavily soiled, use a mild detergent. Never use strong detergents or solvents such as alcohol or thinner.
3.Use a blower or lens paper to clean the lens, and be careful not to scratch or mar the lens.
CAUTION
Do not unplug the power cable from the wall outlet under any one of the following circumstances. Doing so can cause damage to the pro- jector:
•While the message "Please wait a moment." appears. This mes- sage will be displayed after the projector is turned off.
•Immediately after the power cable is plugged into the wall outlet (the POWER indicator has not changed to a steady orange glow).
•Immediately after the cooling fan stops working (The cooling fan continues to work for 90 seconds (2 minutes in the optional ex- tended life lamp GT60LPS) after the projector is turned off with the POWER button).
CAUTION
•Do not try to touch the ventilation outlets as they can become heated while the projector is turned on.
•Do not put the projector on its side when the lamp is turned on. Doing so may cause damage to the projector.
•Before shipping this projector, remove the lens and attach the lens hood cap.
The Lens Shift mechanism may encounter damage caused by im- proper handling during transportation.
•Do not eject a PC card or LAN card while its data is being ac- cessed. Doing so can damage your PC card or LAN card.
Lamp Replacement
•To replace the lamp, follow all instructions provided on page
•Be sure to replace the lamp when the message "The Lamp has reached the end of its usable life. Please replace the lamp." ap- pears. If you continue to use the lamp after the lamp has reached the end of its usable life, the lamp bulb may shatter, and pieces of glass may be scattered in the lamp case. Do not touch them as the pieces of glass may cause injury. If this happens, contact your NEC dealer for lamp replacement.
•Allow a minimum of 90 seconds (2 minutes in the optional extended life lamp GT60LPS) to elapse after turning off the projector. Then turn off the main power and disconnect the power cable and allow 60 minutes to cool the projector before replacing the lamp.
•The projector must be operated with two lamp housings installed regardless of whether or not the lamp is active. Failure to do so may degrade the performance of the projector such as screen flicker or loss of lamp life. If one lamp has reached the end of its usable life, replace it with a new one as soon as possible.
Fire and Shock Precautions
1.Ensure that there is sufficient ventilation and that vents are unob- structed to prevent the
2.Prevent foreign objects such as paper clips and bits of paper from falling into your projector. Do not attempt to retrieve any objects that might fall into your projector. Do not insert any metal objects such as a wire or screwdriver into your projector. If something should fall into your projector, disconnect it immediately and have the ob- ject removed by a qualified NEC service personnel.
3.Do not place any liquids on top of your projector.
4.When using a LAN cable:
For safety, do not connect to the connector for peripheral device wiring that might have excessive Voltage.
CAUTION
•Do not look into the lens while the projector is on. Serious damage to your eyes could result.
•Keep any items such as magnifying glass out of the light path of the projector. The light being projected from the lens is extensive, therefore any kind of abnormal objects that can redirect light com- ing out of the lens, can cause unpredictable outcome such as fire or injury to the eyes.
•Do not cover the lens with the supplied lens hood cap or equiva- lent while the projector is on. Doing so can lead to melting of the cap and possibly burning your hands due to the heat emitted from the light output.
