Lamp Replacement

To replace the lamp, follow all instructions provided on page E-34.

Be sure to replace the lamp when the message "The lamp has reached the end of its usable life. Please replace the lamp." appears. 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 to elapse after turning off the projector. Then disconnect the power cable and allow 60 minutes to cool the projector before replacing the lamp.

Fire and Shock Precautions

1.Ensure that there is sufficient ventilation and that vents are unobstructed to prevent the build-up of heat inside your pro- jector. Allow at least 3 inches (10cm) of space between your projector and a wall.

2.Prevent foreign objects such as paper clips and bits of pa- per 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, dis- connect it immediately and have the object removed by a qualified NEC service personnel.

3.Do not place any liquids on top of your projector.

Do not look into the lens while the projector is on. Serious dam- age 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 exten- sive, therefore any kind of abnormal objects that can redirect light coming 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 cap or equivalent 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.
