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.

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).

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.)
