Using Remote Mouse Receiver
The remote mouse receiver enables you to operate your computer’s mouse functions from the remote control (Computer mode). It is
a great convenience for clicking through your computer-generated presentations.To return to the Projector mode, press the PJ button
(lit red).
Connecting the remote mouse receiver to your computer
If you wish to use the remote mouse function, connect the mouse receiver and computer.
The mouse receiver can be connected directly to the computer using the USB terminal.
To connect it to the computer using the mouse (PS/2) terminal, do so using the PS/2 adapter.
NOTE: Depending on the type of connection or OS installed on your computer, you may have to restart your computer or change your
computer settings.
When connecting using the USB terminal
For PC, the mouse receiver can only be used with a Windows
98, Windows ME or Windows 2000 operating system.
NOTE:
•Wait at least 5 seconds after disconnecting the mouse receiver
before reconnecting it and vice versa. The computer may not
identify the mouse receiver if it is repeatedly connected and
disconnected in rapid intervals.
•When using the PS/2 adapter, be sure to attach the PS/2 adapter
to the remote mouse receiver first. Do not connect or discon-
nect the USB connector of the remote mouse receiver with
the PS/2 adapter on the mouse (PS/2) port of your PC. Doing
so can result in your PC failing to detect the remote mouse
receiver.

2. INSTALLATION
This section describes how to set up your VT45 projector and
how to connect video and audio sources.
Setting up Your Projector
Your VT45 Projector is simple to set up and use. But before you
get started, you must first:
1. Determine the image size.
2. Set up a screen or select a non-glossy white wall onto which
you can project your image.
Ensure that the power cable and any other cables connecting to
video sources are disconnected before moving the projector.
When moving the projector or when it is not in use, cover the
lens with the lens cap.

RCANCEL
Screen Top view
Screen Side view
Using a Tabletop or Cart
1. Place your projector on a flat level surface at the optimal dis-
tance from the screen or wall so you realize the size image
you want. (Avoid having bright room lighting or sun light
directly on the screen or wall where you’ll be projecting the
image.)
2. Connect the power cable, remove the lens cap and turn the
projector on. (If no input signal is available, the projector
will display a background image.)
3. Ensure that the projector is square to the screen.5. To center the image vertically, lift the front edge of the pro-
jector and press the One-Touch Tilt button on the front side
of the projector to release the Front Adjustable foot.
Selecting a Location
The further your projector is from the screen or wall, the larger
the image. The minimum size the image can be is approximately
25 (0.64 m) measured diagonally when the projector is roughly
3 feet (1.0 m) from the wall or screen. The largest the image can
be is 300 (7.6 m) when the projector is about 39.3 feet (12.0 m)
from the wall or screen.
4. Move the projector left or right to center the image horizon-
tally on the screen.(There is approximately 10 degrees of up and down adjust-
ment for the front of the projector.)
1. Grip the lens shift lever on the top and bottom.
2. Hold the lever to move the lens vertically or horizontally.
NOTE: It may not be possible to obtain maximum shift range
due to the rounded off area near the edge of the lens. The amount
of lens shift adjustable range depends on the direction that the
lens is shifted. See diagram below.

When the projector is positioned upside down in a place such as a tall cabinet or
shelf, follow the below.
•Place the projector on a flat and level surface.
•To avoid accidental button operation, stick the supplied three non-slip rubber
pads on three locations on the projector top cabinet as shown in the drawing.
They are a peel-and –sticker pad. Before use, peel the paper off the back of the

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.
If your projector is mounted on the ceiling and your image is
upside down, use the “Menu” and “Select” buttons on your pro-
jector cabinet or 
 buttons on your remote control to correct
the orientation. (See page E-35.)
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

 buttons on your remote control to correct the orientation.
