E-2

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 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.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.

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, disconnect the plug from the power outlet.

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

CAUTION

1.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.

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 cause damage to the projector.

3.Enable High-Speed Fan mode if you continue to use the projector for consecutive days. (From the menu, select [Advanced] → [High Speed Fan Mode].)

4.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 60 seconds after the projector is turned off).

Lamp Replacement

•To replace the lamp, follow all instructions provided on page E-25.

•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 60 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.

What's in the Box?

Make sure your box contains everything listed. If any pieces are missing, contact your dealer.

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 32˚F (0˚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.

Reflecting the Image

Using a mirror to reflect your projector's image enables you to enjoy a much larger image. Contact your NEC dealer if you need a mirror. If you're using a mirror and your image is inverted, use the MENU and SELECT buttons on your projector cabinet or your remote control to correct the orientation. (See page E-22.)

*If the screen goes blank while using your remote control, it may be the result of the computer's screen-saver or power management software.

*If you accidentally hit the POWER (ON/STAND BY) button on the remote control, wait 60 seconds and then press the POWER (ON/STAND BY) button again to resume.
