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.
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 projector:
* While the Hour Glass icon appears.
* While the message Please wait a little. 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 amber
glow).
* Immediately after the cooling fan stops working (The cooling
fan continues to work for 90 seconds after the projector is
turned off with the POWER button).
* While the POWER and the STATUS indicators are alternately
flashing. 
						

							EÐ4
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.

jector to project images from behind the screen, and the projector can
be permanently mounted on a ceiling*
1. The remote control can be
used wirelessly.
Features youÕll enjoy:
¥ Simple set up and operation.
¥ Hot air blown from the vents does not bother the audience dur-
ing your presentation since the vents are located on the side.
¥ A high-performance DC130 watt lamp.
¥ The supplied card wireless remote control that operates the pro-
jector from the front and the rear.
¥ The image can be projected between 36 and 200 inches (mea-
sured diagonally).

so that the image is square.
¥ You can choose between video modes depending on your source:
normal for a typical picture, natural for true color reproduc-
tion.
¥ The built-in PC Card Viewer allows you to start your presenta-
tion even when a PC is not available at the site.
