Important Information

Fire and Shock Precautions

• 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 (10cm) of space between your projector and a wall.

• Do not try to touch the ventilation outlet on the right front (when seen from the front) as it can become heated while the projector is turned on and immediately after the projector is turned off.

• 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 project. If something should fall into your projector, disconnect it immediately and have the object removed by a qualified service personnel.

• Do not place any objects on top of the projector.

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

• 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.

• Do not look into the lens while the projector is on. Serious 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 black 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.

• 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.

• Handle the power cable carefully. A damaged or frayed power cable can cause electric shock or fire.

- Do not use any power cables than the supplied one.

- Do not bend or tug the power cable excessively.

- Do not place the power cable under the projector, or any heavy object.

- Do not cover the power cable with other soft materials such as rugs.

- Do not heat the power cable

- Do not handle the power plug with wet hands.

•Turn off the projector, unplug the power cable and have the object removed by a qualified NEC service personnel under the following conditions:

- When the power cable or plug is damaged or frayed.

- If liquid has been spilled into the projector, or if it has been exposed to rain or water.

- If the projector does not operate normally when you follow the instructions described in this user's manual.

- If the projector has been dropped or the cabinet has been damaged.

- If the projector exhibits a distinct change in performance, indicating a need for service.

- If the projector is not to be used for an extended period of time.

• Disconnect the power cable and any other cables before carrying the projector

•Turn off the projector and unplug the power cable before cleaning the cabinet or replacing the lamp.

CAUTION

• Do no use the tilt-foot for purposes other than originally intended. Misuses such as using the tilt foot to carry or hang (from the wall or ceiling) the projector 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 [Setup - Options] → [Fan Mode] → [High].)

• Do not unplug the power cable from the wall outlet or projector when the projector is powered on. Doing so can cause damage to the AC IN connector of the projector and (or) the prong plug of the power cable.

• Do not turn off the AC power for 60 seconds after the lamp is turned on and while the POWER indicator is blinking green. Doing so could cause premature lamp failure.

Important Information

Remote Control Precautions

• Handle the remote control carefully.

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

•Avoid excessive heat and humidity.

• Do not heat, take apart, or throw batteries into fire.

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

• Ensure that you have the batteries' polarity (+/–) aligned correctly.

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

• Dispose of used batteries according to your local regulations.

Lamp Replacement

•To replace the lamp, follow all instructions provided on page 47 to 49.

• 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 dealer for lamp replacement.

A Lamp Characteristic

The projector has a high-pressure mercury lamp as a light source. A lamp has a characteristic that its brightness gradually decreases with age. Also repeatedly turning the lamp on and off will increase the possibility of its lower brightness.

CAUTION:

When removing the lamp from a ceiling-mounted projector, make sure that no one is under the projector. Glass fragments could fall if the lamp has been burned out.

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 104˚F (40˚C). (Eco mode selected automatically at 95°F to 104°F/35°C to 40°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 when a smaller space is required. Contact your NEC dealer if you need a mirror system. If you're using a mirror system and your image is inverted, use the MENU and SELECT buttons on your projector cabinet or your remote control to correct the orientation. (→ page 41)

2. Installation and Connections

 Making Connections

Connecting Your PC or Macintosh Computer

NOTE: When using with a notebook PC, be sure to connect the projector and notebook PC while the projector is in standby mode and before turning on the power to the notebook PC. In most cases the output signal from the notebook PC is not turned on unless connected to the projector before being powered up. * If the screen goes blank while using your remote control, it may be the result of the computer's screen-saver or power manage-

ment software.

Enabling the computer’s external display

Displaying an image on the notebook PC’s screen does not necessarily mean it outputs a signal to the projector. When using a PC compatible laptop, a combination of function keys will enable/disable the external display. Usually, the combination of the ‘Fn” key along with one of the 12 function keys gets the external display to come on or off. For example, NEC laptops use Fn + F3, while Dell laptops use Fn + F8 key combinations to toggle through external display selections.

NOTE: You can check the horizontal frequency of the current signal in the projector’s menu under Information. If it reads “0kHz”, this means there is no signal being output from the computer. See page 44 or go to next step.

• Enabling the computer’s external display.

• Non-standard signal output from the computer

If the output signal from a notebook PC is not an industry standard, the projected image may not be displayed correctly. Should this happen, deactivate the notebook PC’s LCD screen when the projector display is in use. Each notebook PC has a different way of deactivate/reactivate the local LCD screens as described in the previous step. Refer to your computer’s documentation for detailed information.

• Image displayed is incorrect when using a Macintosh

When using a Macintosh with the projector, set the DIPswitch of the Mac adapter (not supplied with the projector) according to your resolution. After setting, restart your Macintosh for the changes to take affect.

For setting display modes other than those supported by your Macintosh and the projector, changing the DIP switch on a Mac adapter may bounce an image slightly or may display nothing. Should this happen, set the DIP switch to the 13” fixed mode and then restart your Macintosh. After that, restore the DIP switches to a displayable mode and then restart the Macintosh again.

NOTE: A Video Adapter cable manufactured by Apple Computer is needed for a PowerBook which does not have a mini D-Sub 15-pin connector.

• Mirroring on a PowerBook

* When using the projector with a Macintosh PowerBook, output may not be set to 1024 x 768 unless “mirror-

ing” is off on your PowerBook. Refer to owner’s manual supplied with your Macintosh computer for mirroring.

• Folders or icons are hidden on the Macintosh screen

Folders or icons may not be seen on the screen. Should this happen, select [View] → [Arrange] from the Apple menu and arrange icons.
