Important Safeguards
These safety instructions are to ensure the long life of your LCD projector and
to prevent fire and shock. Please read them carefully and heed all warnings.
Installation
1. For best results, use your LCD 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 LCD 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 LCD projector carefully. Dropping or jarring can damage
internal components.
6. Do not place heavy objects on top of the LCD projector.
7. If installing the LCD projector on the ceiling:
a. The ceiling must be strong enough to support the LCD projector and the
installation must be in accordance with any local building codes.
b. The LCD projector must be installed by qualified NEC service personnel.
Power Supply
1. The LCD projector is designed to operate on a power supply of 100-120 or
220-240V 50/60 HzAC. Ensure that your power supply fits this requirement
before attempting to use your LCD projector.
2. Handle the power cable carefully and avoid excessive bending. A damaged
cord can cause electric shock or fire.
3.If the LCD projector is not to be used for an extended period of time,
disconnect the plug from the power outlet.
Cleaning
1. Unplug the LCD 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.
4. Clean the air filter with a vacuum cleaner after every 100 hours of operation.
a. Clean the outside of the filter with a vacuum cleaner.
b. Do not use water or any other liquid to clean the air filter.
c. Do not operate your LCD projector without the air filter.
Lamp Replacement
• Be sure to replace the lamp when the Status light comes on. If you continue
to use the lamp after 2000 hours 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.
• Allow a minimum of ONE minute to elapse between turning the lamp off and
on. High voltage is applied to the lamp immediately when the power is turned
on. Therefore turning the power off and quickly back on may shorten the life
of your lamp and result in damage to your LCD projector.
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 LCD projector. Allow at least 3
inches (10cm) of space between your LCD projector and a wall.
2. Prevent foreign objects such as paper clips and bits of paper from falling into
your LCD 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 LCD project. If something should fall into your projector, discon-
nect it immediately and have the object removed by a qualified NEC service
person.
3. Do not place any liquids on top of your LCD projector.
• Do not look into the lens while the projector is on. Serious
damage to your eyes could result.
• Do not look into the laser pointer while it is on and do not point
the laser beam at another person. Serious injury could result.

This section describes how to set up your MultiSync MT1020/MT820 LCD
projector and how to connect video and audio sources.
Setting Up Your MultiSync MT1020/MT820
LCD Projector
Your MultiSync MT1020/MT820 LCD 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 LCD Projector Always carry your LCD projector by the
handle. Ensure that the power cord 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.
INSTALLATION2
Carrying handle
Pull out
Selecting A Location The further your LCD projector is from the screen or
wall, the larger the image. The minimum size the image can be is approxi-
mately 20" (0.5 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 40.03 feet (12.2 m) from the wall or screen.

Using A Tabletop Or Cart
1. Place your LCD 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. (A)
5. To center the image vertically (B), lift the front edge of the projector
and press the buttons on the front of the projector, just above the
feet, to release the one-touch tilt feet. (There is approximately 10.5˚
of up and down adjustment for 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 projector cabinet or (▲) (▼) buttons on your
remote control to correct the orientation. (See page 60.)
Reflecting The Image
Using a mirror to reflect your LCD 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. (See page 60.)
Rear Screen Projection
You can use your MultiSync MT1020/MT820 LCD projector to project an image from
the rear onto a transparent screen. The distance the projector must be from the screen is
the same as if you were projecting the image from the front. Contact your NEC dealer
if you need a transparent screen.
If you're projecting the image from the rear and your image is inverted, use the “Menu"
and "Select" buttons on your projector cabinet or (▲) (▼) buttons on your remote
control to correct the image. (See page 60 .)

Remote Control Guideline
1. Plug the serial cable with the remote mouse receiver into your computer's mouse port and restart your computer to gain remote mouse
control.
2. When using the remote control's built-in infrared mouse on a laptop computer, the laptop's mouse, trackball or trackpad will be disabled.
Disconnect the infrared receiver and restart your computer to regain trackball or trackpad mouse control.
3. If the screen goes blank while using your remote control, it may be the result of the computer's screen-saver or power management
software. If you accidentally hit the OFF button on the remote control, wait one full minute and then press the ON button to resume.

3. Use the MultiCable that's supplied to connect your PC or Macintosh computer to the
LCD projector. For a PC, use the smaller 15-pin connector on the cable to connect to
your computer's video port; use the larger 15-pin connector on the cable to connect
to the projector's RGB 1 input. For Macintosh, use the larger 15-pin connector on the
cable to connect to your computer's video port; use the smaller 15-pin connector on
the cable to connect to the projector's RGB 2 input. (You can also use your own
video cable if you wish. For a PC cable, use the smaller 15-pin connector RGB 2 on
the projector. For a Macintosh cable, use the larger 15-pin connector RGB 1 on the
projector.)
4. Turn on the LCD projector and the computer.
5. If the projector goes blank after a period of inactivity, it may be caused by a screen
saver installed on the computer you've connected to the projector.
NOTE: Refer to your computer's owner's manual for more information about your
computer's video output requirements and any special identification or configuring your
projector's image and monitor may require.
