3. Use a blower or lens paper to clean the lens, and be careful

not to scratch or mar the lens.

Lamp Replacement

• To replace the lamp, follow all instructions provided on page

E-33.

• Be sure to replace the lamp when the Status light comes

on. If you continue to use the lamp after 1000 hours of use,

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 ONE minute to elapse between turning

the lamp o and on.

High voltage is applied to the lamp immediately when the

power is turned on.

Therefore turning the power o and quickly back on may

shorten the life of your lamp and result in damage to your

projector.

Important Safeguards

These safety instructions are to ensure the long life of

your projector and to prevent re 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 at, 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 inter-

nal components.

5. Handle your projector carefully. Dropping or jarring can dam-

age 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 qualied technicians

in order to ensure proper operation and reduce the risk

of bodily injury.

c. In addition, the ceiling must be strong enough to support

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 ts this requirement before attempting to use your

projector.

2. Handle the power cable carefully and avoid excessive bend-

ing. A damaged cord can cause electric shock or re.

3. If the projector is not to be used for an extended period of

time, disconnect the plug from the power outlet.

E–4

Fire and Shock Precautions

1. Ensure that there is sucient ventilation and that vents are

unobstructed to prevent the build-up of heat inside your pro-

jector. Allow at least 3 inches (10cm) of space between your

projector and a wall.

2. Prevent foreign objects such as paper clips and bits of pa-

per from falling into your projector. Do not attempt to re-

trieve 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

qualied NEC service personnel.

3. Do not place any liquids on top of your projector.

Warnings

• 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 unpre-

dictable outcome such as re or injury to the eyes.

• Do not cover the lens with the supplied lens cap or equiva-

lent 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.

• Do not hold the lens part. Doing so may cause the risk of

injuly.

For the optional full function remote control with

the laser pointer

• Do not look into the laser pointer while it is on and do

not point the laser beam at another person. Serious in-

jury could result.

2. INSTALLATION

This section describes how to set up your MultiSync LT84/LT140

projector and how to connect video and audio sources.

Setting up Your Projector

Your MultiSync LT84/LT140 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 in the supplied

soft carrying case.

NOTE: Do not put a notebook computer in the soft carrying case.

Doing so can cause damage to the computer. When moving the pro-

jector or when it is not in use, cover the lens cap.

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.)

5. To center the image vertically, lift the front edge of the projector

and press the One-Push Tilt buttons on the front side of the pro-

jector, just above the feet, to release the Front Adjustable feet.

(There is approximately 5 degrees of up and down adjustment for

the front of the projector.)

6. If necessary, adjust the front or rear feet to properly position the

projected image on the screen.

If the projected image does not appear square to the screen then

use keystone correction for proper adjustment. The Lever-Type

Adjustable Rear foot height can be changed up to 3 degrees.

2. Connect one end of your RCA cable to the video output connector

on the back of your VCR or laser disc player, connect the other

end to the Video input on your projector. Use standard RCA audio

patch cords to connect the audio from your VCR or laser disc

player to the projector (if your VCR or laser disc player has this

capability). Be careful to keep your right and left channel connec-

tions correct for stereo sound.

3. Turn on the projector and the VCR or laser disc player.

NOTE: Refer to your VCR or laser disc player owner’s manual for

more information about your equipment’s video output requirements.

Connecting Your Computer to the Mouse Output Port

(only when using the optional full function remote control)

NOTE: To use the Mouse Output port, you need the optional serial

cable, the optional mouse adapter(for IBM PS/2 or Macintosh), and

the optional full function remote control.
