specified by NEC Solutions (America), Inc. in this manual. Failure to comply with this government regulation could
void your right to operate this equipment. This equipment has been tested and found to comply with the limits for a
Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable
protection against harmful interference in a residential installation. This equipment generates, uses, and can radi-
ate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful
interference to radio communications. However, there is no guarantee that interference will not occur in a particular
installation.
If this equipment does cause harmful interference to radio or television reception, which can be determined by
turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the
following measures:
•Reorient or relocate the receiving antenna.
•Increase the separation between the equipment and receiver.
•Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
•Consult the dealer or an experienced radio / TV technician for help.
For UK only: In UK, a BS approved power cable with moulded plug has a Black (five Amps) fuse installed for use with
this equipment. If a power cable is not supplied with this equipment please contact your supplier.
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 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 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 accor-
dance with any local building codes.
d. Please consult your dealer for more information.
Place the projector in a horizontal position
The tilt angle of the projector should not exceed 10 degrees, nor should the projector be installed in any way other than
the desktop and ceiling mount, otherwise lamp life could decrease dramatically.
10˚

Important Information
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 4 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 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.
4. Do not look into the lens while the projector is on. Serious damage to your eyes could result.
5. 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.
6. 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.
7. Do not place any objects, which are easily affected by heat, in front of the projector lens or a projector exhaust
vent.
Doing so could lead to the object melting or getting your hands burned from the heat that is emitted from the
light output and exhaust.
8. The projector is designed to operate on a power supply of 100-240V AC 50/60 Hz. Ensure that your power
supply fits this requirement before attempting to use your projector.
9. Handle the power cable carefully and avoid excessive bending.
A damaged cord can cause electric shock or fire.
10. If the projector is not to be used for an extended period of time, disconnect the plug from the power outlet.
11. Do not touch the power plug during a thunderstorm. Doing so can cause electrical shock or fire.
12. Do not handle the power plug with wet hands.
CAUTION
•Do not try to touch the ventilation outlet on the left side (when seen from the front) as it can become heated
while the projector is turned on.
•Do no use the tilt-foot for purposes other than originally intended. Misuses such as gripping the tilt-foot or
hanging on the wall can cause damage to the projector.
•Do not send the projector in the soft case by parcel delivery service or cargo shipment. The projector inside
the soft case could be damaged.
•Select [High] in Fan mode if you continue to use the projector for consecutive days. (From the menu, select
[Advanced] → [Fan Mode] → [High].)
•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 cooling fans are running. (The cooling fans continue to work for 30 seconds after the projector is
turned off). 
						

							iv
Lamp Replacement
•To replace the lamp, follow all instructions provided on page 46.
•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 30 seconds to elapse after turning off the projector. Then turn off the main power switch,
disconnect the power cable and allow 60 minutes to cool the projector before replacing the lamp.
