2. Installation and Connections
Your projector is simple to set up and use.
But before you get started you must first:
1. Set up a screen and the projector.
NOTE: Using a warped screen can cause an image to appear distorted.
2. Connect your computer or video equipment to the projector. See page 19 to 28.
NOTE: To connect a network, see page 25.
3. Connect the supplied power cable. See page 29.
NOTE: Ensure that the power cable and any other cables are disconnected before moving the projector. When moving the
projector or when it is not in use, close the mirror cover on the top cabinet.
This section describes how to set up your projector and how to connect video and audio sources.
When installing the projector for the first time, read the WT615/WT610 Setup Guide carefully.

2. Installation and Connections

 Setting Up the Screen and the Projector
1.Refer to Throw Distance (C) in the diagram and use a distance between the screen and projector that corre-
sponds to the screen size.
As an example, when projecting to a 60 screen, set the projector with a separation of approximately 10.4/26.3
cm from the screen.
2. Refer to Height (D) below and adjust the screen height, or adjust the height of the projector stand.
As an example, when projecting to a 60 screen, adjust the height from the feet of the projector to the lower
edge of the screen to approximately 19.0/48.2 cm.

Screens Suited
•Screens with a soiled, scratched, or discolored area will not produce a clean image. Care
should be used in the handling of the screen.

Not recommended•Use a panel or tension type screen that has a flat surface.
Do not use roll type screens and other screens that bend or form a wavy
surface easily. Doing so will result in increased distortion of the projected
image. •The projector can accommdate screen sizes from 40” (81.3 cm/32.0” W 
 61.0 cm/24.0” H)
to 100 inch (203.2 cm/80.0” W 
 152.4 cm/60.0” H).
•View the screen directly from the side so that it is perfectly vertical.
A slanted screen will result in increased keystone distortion.
•In using this projector, increasing the screen size will move the projection position upward. To
accommodate this, please use a screen that can be raised and lowered to a given screen
position. See page 16 for information about the positioning relationships between the screen
and this projector.
•High gain type screens are not optimal for use with this projector. The lower the screen gain
(i.e., screen gain on the order of 1), the better the appearance of the projected image.
For more information about screen gain, consult catalogs from screen manufacturers.
•Screen frames or pen shelves that protrude from the front of the screen surface may block
some of the light from the projector.
•Due to the projection angle of the projector, many standard rear projection screens may pro-
duce uneven brightness, hot spotting or not produce maximum brightness to the viewer. For
more details utilizing rear projection screens and their applications with this projector, please
contact your NEC dealer.
•Controlled ambient light environments will allow for an image of higher contrast and depth to
be displayed.
Level
Stands Suited
•Use a stand that will allow this projector to be set up in a level condition. Adjust the feet of the
stand to make sure it is level.
Recommended
Recommended•In using this projector, increasing the screen size will move the projection position upward. To
accommodate this, please use a stand that has a height positioning adjustment. See page 16
for information about the positioning relationships between the screen and this projector.

2. Installation and Connections
Ambient environmental condition
•Do not place the screen near vents.
Air movement hitting the screen, causing the projected image to ripple.
•Do not illuminate the projector with strong light sources such as halogen lamp.
Doing so can cause the object detection sensor to malfunction, resulting in the projector not turning on.
Precautions for using the electronic pen (WT615 only)
•Use a hard-surface screen because you tap the screen using the electronic pen. Supported screen sizes are 40
to 80 (101.6 to 203.2 cm).
•Keep in mind that the electronic pen tip can cause scratches on the screen surface as the pen tip is made of
hard material.
•Do not use the electronic pen under the following conditions. Otherwise, the electronic pen may not work
properly.
-Near a device such as a CRT monitor or a TV set.
-In a room with the ceiling and walls made of metal which is prone to reflect sound waves.
-In a noisy place or a place where loud sounds can be heard
-In direct sunlight or near an inverter fluorescent lamp.
-Near an air conditioner or air blower
•Do not hold any part ahead of the black ring part of the electronic pen. Otherwise, the electronic pen may not
work properly.
•Do not use two or more electronic pens and projectors at the same time in the same room. Be sure to use the
electronic pen and the projector on a one-to-one basis.
•Operational temperature for electronic pen is 59° to 95°F (15° to 35°C).

 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 the RGB output unless the notebook PC is turned on after
connecting with the projector.
* If the screen goes blank while using your notebook PC, it may be the result of the computers screen-saver or power manage-
ment software.
When Viewing a DVI Digital Signal
To project a DVI digital signal, be sure to connect the PC and the projector using a DVI cable (not supplied) before
turning on your PC or projector. Turn on the projector first and select DVI (DIGITAL) from the source menu before
turning on your PC.
Failure to do so may not activate the digital output of the graphics card resulting in no picture being displayed. Should
this happen, restart your PC.
Do not disconnect the DVI cable while the projector is running. If the signal cable has been disconnected and then re-
connected, an image may not be correctly displayed. Should this happen, restart your PC.
NOTE:
•Use a DVI cable or the one compliant with DDWG (Digital Display Working Group) DVI (Digital Visual Interface) revision 1.0
standard. The DVI cable should be within 5 m (196) long. Both single and dual types of DVI cable can be used.
•The DVI (DIGITAL) connector accepts VGA (640x480), SVGA (800x600), 1152x864, XGA (1024x768) and SXGA (1280x1024 @
up to 60Hz).
