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.
