Important Safeguards
These safety instructions are to ensure the long life of
your projector and to prevent fire and shock. Please read
them carefully and heed all warnings.
Installation
1. For best results, use your projector in a darkened room.
2. Place the projector on a flat, level surface in a dry area away
from dust and moisture.
3. Do not place your projector in direct sunlight, near heaters
or heat radiating appliances.
4. Exposure to direct sunlight, smoke or steam can harm in-
ternal components.
5. Handle your projector carefully. Dropping or jarring can dam-
age internal components.
6. Do not place heavy objects on top of the projector.
7. If you wish to have the projector installed on the ceiling:
a.Do not attempt to install the projector yourself.
b. The projector must be installed by qualified technicians
in order to ensure proper operation and reduce the risk
of bodily injury.
c. In addition, the ceiling must be strong enough to support
the projector and the installation must be in accordance
with any local building codes.
d. Please consult your dealer for more information.
Power Supply
1. The projector is designed to operate on a power supply of
100-120 or 200-240 V 50/60 Hz AC. Ensure that your power
supply fits this requirement before attempting to use your
projector.
2. Handle the power cable carefully and avoid excessive bend-
ing. 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.
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. 
						

							EÐ4
Lamp Replacement
¥ To replace the lamp, follow all instructions provided on page
E-33.
¥ Be sure to replace the lamp when the Status light comes
on. If you continue to use the lamp after 2000 hours (1500
hours : MT1045) of use, 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 ONE minute 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 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.
¥ Do not look into the laser pointer while it is on and do not
point the laser beam at another person. Serious injury could
result.
