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).

Important Information

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 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. See page 41.

2. Installation and Connections

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.

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.

Connecting Your PC or Macintosh Computer

NOTE: • VT676/VT670/VT575/VT470: The COMPUTER 1 connector supports Plug & Play (DDC2).

• VT47: The COMPUTER connector supports Plug & Play (DDC2).

Replacing the Lamp

After your lamp has been operating for 2000* hours (up to 3000* hours in Eco mode) or longer, the LAMP indicator in the cabinet will blink red and the message “The lamp has reached the end of its usable life. Please replace the lamp.” will appear. Even though the lamp may still be working, replace it at 2000* (up to 3000* hours in Eco mode) hours to maintain optimal projector performance. After replacing the lamp, be sure to clear the lamp hour meter. See page 47.

CAUTION

DO NOT TOUCH THE LAMP immediately after it has been used. It will be extremely hot. Turn the projector off, wait 30 seconds, turn off the main power switch and then disconnect the power cable. Allow at least one hour for the lamp to cool before handling.

DO NOT REMOVE ANY SCREWS except two lamp case screws. You could receive an electric shock.

Do not break the glass on the lamp housing.

Keep finger prints off the glass surface on the lamp housing. Leaving finger prints in the glass surface might cause an unwanted shadow and poor picture quality.

The projector will turn off and go into standby mode after 2100* (up to 3100* hours in Eco mode) hours of service. If this happens, be sure to replace the lamp. If you continue to use the lamp after 2000* hours (up to 3000* hours in Eco mode) of use, 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.

*NOTE: Lamp life for VT575/VT47 is 3000 hours in Normal mode and 4000 hours in Eco mode.

The projector will turn off and go into standby mode after 3100 (up to 4100 hours in Eco mode) hours of service.

To replace the lamp:

Optional lamp and tools needed for replacement:

Replacement lamp VT75LP (VT676/VT670/VT470) or VT70LP (VT575/VT47)

Common Problems & Solutions (See also "Power/Status/Lamp Indicator" on page 53.)

 

 

 

Problem

Check These Items

 

Does not turn on

• Check that the power cable is plugged in and that the power button on the projector cabinet or the remote

 

 

control is on. See pages 20 and 21.

 

 

• Ensure that the lamp cover is installed correctly. See page 51.

 

 

• Check to see if the projector has overheated or the lamp usage exceeds 2100* hours (up to 3100* hours : Eco

 

 

mode). If there is insufficient ventilation around the projector or if the room where you’re presenting is par-

 

 

ticularly warm, move the projector to a cooler location.

 

 

* VT575 and VT47: 3100 hours (up to 4100 hours in Eco mode).

 

 

• The lamp may fail to light. Wait a full minute and then turn on the power again.

 

 

• The lamp has reached the end of its usable life. Replace the lamp.

 

 

 

 

Will turn off

• Ensure that the Power Management is off. See page 45.

 

 

 

 

No picture

• Use the VIDEO, the S-VIDEO or the COMPUTER button on the remote control to select your source (Computer,

 

 

Video or S-Video). See page 23. If there is still no picture, press the button again.

 

 

• Ensure your cables are connected properly.

 

 

• Use menus to adjust the brightness and contrast. See page 38.

 

 

• Remove the lens cap.

 

 

• Reset the settings or adjustments to factory preset levels using the “Default” in the Menu. See page 47.

 

 

• Enter your registered keyword if the Security function is enabled. See page 42.

 

 

• 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.

 

 

• See also the next page.

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.

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 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.

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 “mirroring” 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.
