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 heat-
ers or heat radiating appliances.
4. Exposure to direct sunlight, smoke or steam can harm
internal components.
5. Handle your projector carefully. Dropping or jarring can
damage 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 techni-
cians in order to ensure proper operation and reduce
the risk of bodily injury.
c. In addition, the ceiling must be strong enough to sup-
port the projector and the installation must be in ac-
cordance 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
bending. 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.
CAUTION
Do not turn off the main power or unplug the power cable
from the wall outlet under any one of the following circum-
stances. Doing so can cause damage to the projector:
•Immediately after the power cable is plugged into the wall
outlet (when the POWER indicator has not changed to a
steady orange glow).
•Immediately after the cooling fan stops working (The cool-
ing fan continues to work for 60 seconds after the pro-
jector is turned off with the POWER button).
CAUTION
Avoid  displaying  stationary images for a prolonged period
of time.
Doing so can result in these images being temporarily sus-
tained on the surface of the LCD panel.
If this should happen, continue to use your projector. The
static background from previous images will disappear.
CAUTION
Do not put the projector on its side when the lamp is turned
on.
Doing so may cause damage to the projector. 
						

							E–4
Lamp Replacement
•To replace the lamp, follow all instructions provided on
page E-38.
•Be sure to replace the lamp when the message "The
lamp has reached the end of its usable life. Please re-
place 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 scat-
tered 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 60 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 projector. 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
paper 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 screw-
driver 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. Seri-
ous 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 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.
