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 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 100-240 V 50/60 Hz AC. 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
1. Do not try to touch the ventilation outlet on the right and rear side (when seen from the front) as it can
become heated while the projector is turned on.
2. Do not 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.
Before putting the projector in the soft case, be sure to retract the feet. Failure to do so may cause damage
to the projector.
3. When carrying the projector, heed the following:
• Ensure that the power cable and any other cables are disconnected before moving the projector.
• Cover the lens with the supplied lens cap so as not to scratch the lens surface.
4. 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.
5. Select “High” in the Fan mode if you continue to use the projector for consecutive days. (From the menu,
select [Advanced] → [Fan Mode] → [High].)
6. 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 projector is turned on.
* While the cooling fans are running. (The cooling fans continue to work for 60 seconds after the projector
is turned off).
7. If you accidentally turn off the main power by disconnecting the power cable or press the main power switch
during cooling down, wait 10 minutes and then turn on the projector to resume. This is to protect the lamp.

1. INTRODUCTION
Remote control
• The infrared signal operates by line-of-sight up to a distance of about 22 feet/7 m and within a 60-degree
angle of the remote sensor on the projector cabinet.
• The projector will not respond if there are objects between the remote control and the sensor, or if strong light
falls on the sensor. Weak batteries will also prevent the remote control from properly operating the projector.

2. INSTALLATION AND CONNECTIONS
WARNING
* Installing your projector on the ceiling must be done by a qualified technician. Contact your NEC
dealer for more information.
* Do not attempt to install the projector yourself.
• Only use your projector on a solid, level surface. If the projector falls to the ground, you can be injured and the
projector severely damaged.
• Do not use the projector where temperatures vary greatly. The projector must be used at temperatures between 41˚F (5˚C) and 95˚F (35˚C).
• Do not expose the projector to moisture, dust, or smoke. This will harm the screen image.
• Ensure that you have adequate ventilation around your projector so heat can dissipate. Do not cover the
vents on the side or the front of the projector.
Rear Projection Applications
The projector has the ability to be used in a rear projection application. When used with a third party mirror and
frame system, rear projection allows you to achieve a larger image size in less distance than a traditional front
projection installation. If space constraints exist, please contact your authorized NEC reseller regarding a rear
projection solution. Refer to page E-38 on how to change the projector orientation for use in a rear projection
application.
