E–2

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 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 ac­cordance 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.

CAUTION

Do not turn off the main power or unplug the power cable
from the wall outlet under any one of the following circum­stances. 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 cool­ing fan continues to work for 60 seconds after the pro­jector 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 sus­tained 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.

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.

E–3

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 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 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 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.

• Do not look into the lens while the projector is on. Seri­ous 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.

2. INSTALLATION

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.

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 dis­tance 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 horizon­tally on the screen.

5. To center the image vertically, lift the front edge of the pro­jector and press the One-Touch Tilt button on the front side
of the projector to release the Front Adjustable foot.

Side view

Screen

(There is approximately 10 degrees of up and down adjust­ment for the front of the projector.)

Adjusting the Tilt Foot

1) Press and hold the Tilt button on the front of the pro­jector.

2) Lift the front edge of the projector to the height you
want, and release the button to lock the Adjustable
Tilt Foot.

IMPORTANT:

• The projector should be unplugged if it will not to be used for an
extended period.

• To turn off the image and sound briefly (five minutes or less), use
the “Picture Mute” button instead of turning the projector off and
on.

• The projector will display a black, blue image or logo if no input
signal is present.

• Do not turn the projector off and then immediately back on. The
projector needs to cool for 60 seconds before it can be restarted.

CAUTION

Avoid displaying stationary images for a prolonged period
of time.
Doing so can result in these images being temporarily sus­tained 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 turn off the main power or unplug the power cable
from the wall outlet under any one of the following circum­stances. 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 cool­ing fan continues to work for 60 seconds after the pro­jector is turned off with the POWER button).

Adjusts the brightness level or the back raster intensity.

<Contrast>
Adjusts the intensity of the image according to the incoming
signal.

<Color>
Increases or decreases the color saturation level (not valid
for RGB).

<Hue>
Varies the color level from +/- green to +/-blue. The red level
is used as reference. This adjustment is only valid for Video
and Component inputs (Not RGB).

<Sharpness>
Controls the detail of the image for Video (Not for RGB and
Component).

NOTE: The keystone angle can be corrected between 30 degrees
upward and 30 degrees downward at a 0 degree-projection angle.
Depending on the amount of keystone used, the Picture menu
and adjusment bar menus may lie off the edge of the screen.
Depending on the type of graphics being used, the picture may
get blurred or keystone correction may not be possible when ex­cessive keystone correction is used. The idea is, the closer you
are to native resolution, the better image you will see.

This section describes the simple maintenance procedures you
should follow to replace the lamp and clean the filters.

Replacing the Lamp

After your lamp has been operating for 2000 hours (up to 3000
hours in Eco mode) or longer, the “Status” light in the cabinet
will go on and the message 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.

CAUTION

•

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

• DO NOT REMOVE ANY SCREWS except the lamp
cover screw and two lamp case screws. You could re­ceive an electric shock.
The projector will turn off and go into stand by 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.

To replace the lamp:

1. Loosen the lamp cover screw until the screwdriver goes into
a freewheeling condition and remove the lamp cover. The
lamp cover screw is not removable.
