E–3
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 heat-
ers 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 techni-
cians in order to ensure proper operation and reduce
the risk of bodily injury.
c. In addition, the ceiling must be strong enough to sup-
port the projector and the installation must be in ac-
cordance with any local building codes.
d. Please consult your dealer for more information.
Power Supply
1. The projector is designed to operate on a power supply
of 100-120 or 200-240 V 50/60 Hz AC. Ensure that your
power supply fits this requirement before attempting to
use your projector.
2. Handle the power cable carefully and avoid excessive
bending. A damaged cord can cause electric shock or
fire.
3. If the projector is not to be used for an extended period
of time, disconnect the plug from the power outlet.
Cleaning
1. Unplug the projector before cleaning.
2. Clean the cabinet periodically with a damp cloth. If
heavily soiled, use a mild detergent. Never use strong
detergents or solvents such as alcohol or thinner.
3. Use a blower or lens paper to clean the lens, and be
careful not to scratch or mar the lens.
CAUTION
Do not turn off the main power or unplug the power cable
from the wall outlet under any one of the following circum-
stances. Doing so can cause damage to the projector:
• Immediately after the power cable is plugged into the wall
outlet (when the POWER indicator has not changed to a
steady orange glow).
• Immediately after the cooling fan stops working (The cool-
ing fan continues to work for 60 seconds after the pro-
jector is turned off with the POWER button).
CAUTION
Avoid displaying stationary images for a prolonged period
of time.
Doing so can result in these images being temporarily sus-
tained on the surface of the LCD panel.
If this should happen, continue to use your projector. The
static background from previous images will disappear.
CAUTION
Do not put the projector on its side when the lamp is turned
on.
Doing so may cause damage to the projector.
E–4
Lamp Replacement
• To replace the lamp, follow all instructions provided on
page E-38.
• Be sure to replace the lamp when the message "The
lamp has reached the end of its usable life. Please re-
place 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 scat-
tered 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 60 seconds to elapse after turning
off the projector. Then disconnect the power cable and
allow 60 minutes to cool the projector before replacing
the lamp.
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 3 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 screw-
driver 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.
• Do not look into the lens while the projector is on. Seri-
ous 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 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.

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.

This section describes how to set up your VT650 projector and
how to connect video and audio sources.
Setting up Your Projector
Your VT650 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.
Carrying the Projector: Always carry your projector by
the handle. 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.

Adjusting the Tilt Foot
1) Press and hold the Tilt button on the front of the pro-
jector.
2) Lift the front edge of the projector to the height you
want, and release the button to lock the Adjustable
Tilt Foot.
To fine-tune the image’s position vertically on the screen,
rotate the foot. Each of the rear feet height can be
changed up to 0.6” (4mm).
Carrying handle
2. INSTALLATION
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
3.5 feet (1.1 m) from the wall or screen. The largest the image
can be is 300" (7.6 m) when the projector is about 36.6 feet (11.2
m) from the wall or screen.
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.
4. Move the projector left or right to center the image horizon-
tally on 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.
(There is approximately 10 degrees of up and down adjust-
ment for the front of the projector.)
6. If the projected image does not appear square to the screen
then use keystone correction for proper adjustment.
7. Adjust the size of the image using the Zoom lever on the
lens.

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 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
your remote control to correct the orientation. (See page E-35.)
