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.
10˚
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.
iii
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.
• When carrying the projector by the carrying handle, make sure the two screws that attach the carrying handle
to the projector cabinet are tight. (VT676/VT670/VT470 only)
Insufficient tightening of the two screws could result in the projector falling and causing injury.
• Do not send the projector in the soft carrying case by parcel delivery service or cargo shipment. The projector
inside the soft carrying 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 50.
• 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.

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.
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 system. If you're using a mir-
ror system 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 41.

2. Installation and Connections
ᕢ Making Connections
NOTE: When using with a notebook PC, be sure to connect between the projector and the notebook PC before turning on the
power to the notebook PC. In most cases signal cannot be output from RGB output unless the notebook PC is turned on after
connecting with the projector.
* 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.

Connecting your PC or Macintosh computer to your projector will enable you to project your computer's screen image
for an impressive presentation.
To connect to a PC or Macintosh, simply:
1. Turn off the power to your projector and computer.
2. Use the supplied RGB/VGA signal cable to connect your PC or Macintosh to the projector.
3. Connect the supplied power cable. See page 20.
4. Turn on the projector and the computer.
5. If the projector goes blank after a period of inactivity, it may be caused by a screen saver installed on the computer
you've connected to the projector.

• VT47: The COMPUTER connector supports Plug & Play (DDC2).
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: The projector is not compatible with video decoded outputs of either the NEC ISS-6020 and ISS-6010 switchers.
NOTE: An image may not be displayed correctly when a Video or S-Video source is played back via a commercially available scan
converter.
This is because the projector will process a video signal as a computer signal at the default setting. In that case, do the following.
* When an image is displayed with the lower and upper black portion of the screen or a dark image is not displayed correctly:
Project an image to fill the screen and then press the AUTO ADJ button on the remote control or the projector cabinet.

• Adjust "Hue" in "Picture". See page 38.
• Reposition the projector to improve its angle to the screen. See page 24.
• Use the Keystone correction function to correct the trapezoid distortion. See page 26.
• Adjust the focus. See page 25.
• Reposition the projector to improve its angle to the screen. See page 24.
• Ensure that the distance between the projector and screen is within the adjustment range of the lens. See
pages 11 for VT676/VT670/VT575/VT470 and 12 for VT47.
• Condensation may form on the lens if the projector is cold, brought into a warm place and is then turned on.
Should this happen, let the projector stand until there is no condensation on the lens.
• Use the VIDEO, the S-VIDEO or the COMPUTER button on the remote control to select your source (Video, S-
Video or Computer). See page 23.
• Adjust the computer image manually with the Horizontal/Vertical in the “Advanced → Page 2”. See page 45.
• Install new batteries.See page 10.
• Make sure there are no obstacles between you and the projector.
• Stand within 22 feet (7 m) of the projector. See page 10.
• See the POWER/STATUS/LAMP Indicator on page 53.
• Press the AUTO ADJ. button on the projector cabinet or the remote control. See page 28.
• When “Off” is selected in Auto Adjust, adjust the computer image manually with Clock/Phase in “Advanced →
Page 2” in the menu. See pages 45 and 46.

7. Appendix
If there is no picture, or the picture is not displayed correctly.
• Power on process for the projector and the PC.
Be sure to connect the RGB cable between the projector and the computer before turning on the computer.
There are some notebook PCs, which do not output signal unless there is a projector or monitor connected first.
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 46 or go to next step.
• 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 projec-
tor. 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.
• 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 projec-
tor) 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.
