Fire and Shock Precautions1. Ensure that there is sufficient ventilation and that vents are unob-

structed to prevent the build-up of heat inside your projector. Allow atleast 4 inches (10 cm) of space between your projector and a wall.

2. Prevent foreign objects such as paper clips and bits of paper fromfalling into your projector.

Do not attempt to retrieve any objects that might fall into your projec-tor. Do not insert any metal objects such as a wire or screwdriver intoyour projector. If something should fall into your projector, disconnectit immediately and have the object removed by a qualified NEC ser-vice 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 toyour eyes could result.

5. Keep any items such as magnifying glass out of the light path of theprojector. The light being projected from the lens is extensive, there-fore any kind of abnormal objects that can redirect light coming out ofthe lens, can cause unpredictable outcome such as fire or injury tothe eyes.

6. Do not cover the lens with anything other than the built-in lens shutterwhile the projector is on. Doing so can lead to melting of the coverand possibly burning your hands due to the heat emitted from thelight output.

7. The projector is designed to operate on a power supply of 100-120 or200-240 V 50/60 Hz AC. Ensure that your power supply fits this re-quirement before attempting to use your projector.

8. Handle the power cable carefully and avoid excessive bending.A damaged cord can cause electric shock or fire.

9. If the projector is not to be used for an extended period of time, dis-connect the plug from the power outlet.

10. Do not touch the power plug during a thunderstorm. Doing so cancause electrical shock or fire.

11. Do not handle the power plug with wet hands.

CAUTION1. Do not try to touch the ventilation outlet on the rear as it can become

heated while the projector is turned on.

2. 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 causedamage to the projector.

3. When carrying the projector, heed the following:

* Use the supplied soft carrying case. Before putting the projector inthe soft carrying case, be sure to close the lens shutter so as notto mar the lens.

* Do not handle the projector roughly.

* Do not send the soft carrying case by parcel delivery service orcargo shipment. The projector inside the soft carrying case couldbe damaged. (However, it is possible to use it as a carrier case onboard.)

4. Select “High” in the Fan mode if you continue to use the projector forconsecutive days. (From the menu, select [To Advanced Menu] →[Setup 2] → [Fan Mode].)

5. Do not unplug the power cable from the wall outlet under any one ofthe 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 towork for 60 seconds after the projector is turned off).

3. Slip the cover back over the batteries until it snaps into place. Do notmix different types of batteries or new and old batteries.

Remote Control Precautions• Handle the remote control carefully.

• If the remote control gets wet, wipe it dry immediately.

• Avoid excessive heat and humidity.

• If you will not be using the remote control for a long time, remove thebatteries.

• Do not place the batteries upside down.

• Do not use new and old batteries together, or use different types ofbatteries together

Operating Range for Wireless Remote Control

Remote control

Remote sensor onprojector cabinet

Actual operating range may differ from the above drawing.

• The infrared signal operates by line-of-sight up to a distance of about22 feet/7 m and within a 60-degree angle of the remote sensor on theprojector cabinet.

• The projector will not respond if there are objects between the remotecontrol and the sensor, or if strong light falls on the sensor. Weak bat-teries will also prevent the remote control from properly operating theprojector.

INSTALLATION AND CONNECTIONS

This section describes how to set up your projector and how to connect video and audio sources.

To the wall outlet.

Setting Up the Screen and the ProjectorSelecting a LocationThe further your projector is from the screen or wall, the larger the image. The minimum size the image can be is approximately 30" (0.76 m) measureddiagonally when the projector is roughly 44.5 inches (1.1 m) from the wall or screen. The largest the image can be is 200" (5.0 m) when the projector isabout 305.5 inches (7.8 m) from the wall or screen. Use the drawing below as a guide.

Your projector is simple to set up anduse. But before you get started, youmust first:

� Set up a screen and the projector.

� Connect your computer or videoequipment to the projector. Seepages E-12 to 15.

� Connect the supplied power cable.See page E-17.

NOTE: Ensure that the power cable and anyother cables are disconnected before mov-ing the projector. When moving the projec-tor or when it is not in use, close the lensshutter.

NOTE: Distances may vary +/-5%.

Throw Distance and Screen SizeThe following shows the proper relative positions of the projector and screen. Refer to the table to determine the position of installation.

Reflecting the ImageUsing a mirror to reflect your projector's image enables you to enjoy amuch larger image. Contact your NEC dealer if you need a mirror. If you'reusing a mirror and your image is inverted, use the MENU button andSELECT dial on your projector cabinet or the MENU and the ��buttons on your remote control to correct the orientation. (See page E-33.)

WARNING* Installing your projector on the ceiling must be done by a quali-

fied 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 tothe ground, you can be injured and the projector severely damaged.

• Do not use the projector where temperatures vary greatly. The projec-tor 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 harmthe screen image.

• Ensure that you have adequate ventilation around your projector soheat can dissipate. Do not cover the vents on the side or the front ofthe projector.
