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.

Lamp Replacement

• To replace the lamp, follow all instructions provided on page

E-52.

• Be sure to replace the lamp when the message "Lamp Run-

ning Time is Over 1000 Hours!!" 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, con-
tact 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 (10 cm) 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 re-
trieve 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 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

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 coming out of the lens, can cause unpre-
dictable outcome such as fire or injury to the eyes.

• Do not cover the lens with the supplied lens 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.
