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 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 - 240V50 / 60Hz 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 unplug the power cable from the wall outlet under any one of the following circumstances. Doing so can cause damage to the projector:

While the Hour Glass icon appears.
- While the message "Please wait a little." appears. This message will be displayed after the projector is turned off.
- Immediately after the power cable is plugged into the wall outlet (the POWER indicator has not changed to a steady amber glow).
- Immediately after the cooling fan stops working (The cooling fan continues to work for ONE minute after the projector is turned off with the POWER button).
- While the POWER and the STATUS indicators are alternately flashing.

CAUTION

Do not put the projector on its side when the lamp is turned on.

Doing so may cause damage to the projector.

Lamp Replacement

• To replace the lamp, follow all instructions provided on page E-47.
• 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 ONE minute 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.
4. Do not look into the lens while the projector is on. Serious damage to your eyes could result.
5. 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.
6. 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.
7. 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.

2. INSTALLATION

This section describes how to set up your MultiSync MT1055/MT1050/ MT850 projector and how to connect video and audio sources.

Setting up Your Projector

Your MultiSync MT1055/MT1050/MT850 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.

Attaching the lens cap to the lens hood with the supplied string and rivet.

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 30'' (0.76 m) measured diagonally when the projector is roughly 4 feet (1.3 m) from the wall or screen. The largest the image can be is 300'' (7.6 m) when the projector is about 36.8 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.

1. Move the projector left or right to center the image horizontally on the screen.
2. To center the image vertically, lift the front edge of the projector and press the One-Touch Tilt button on the front-left side of the projector to release the Front Adjustable foot.

(There is approximately 5 degrees of up and down adjustment for the front of the projector.)

1. If the projected image does not appear square to the screen then use keystone correction for proper adjustment.
2. Adjust the size of the image using the Zoom ring on the lens.

Adjusting the Tilt Foot

Press and hold the Tilt button on the left side of the projector.

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).

C=Throw distance

D=Vertical distance between lens center and screen bottom (screen top for ceiling installation)

Ceiling Installation

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^ (0^) and 104^ (40^) .
• 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 projector cabinet or button on your remote control to correct the orientation. (See page E-36.)

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 buttons on your remote control to correct the orientation. (See page E-36.)

VCR, DVD Player or LaserDisc Player

NOTE: When using with a notebook PC, be sure to connect between the projector and the notebook PC before turning on the power to the notebook PC. In most cases signal cannot be output from RGB output unless the notebook PC is turned on after connecting with the projector.

NOTE: If using video, S-video, or audio cables, the cables should be 3 m (9.8 feet) or shorter.

Remote Control Guideline for the Remote Control

1. Plug the supplied serial cable with the mouse output port of the projector 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 serial cable from the mouse output port 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.
4. If you accidentally hit the OFF button on the remote control, wait one full minute and then press the ON button to resume.

Connecting Your PC or Macintosh Computer

Connecting your PC or Macintosh computer to your MultiSync MT1055 and MT1050 (XGA) / MT850 (SVGA) projector will enable you to project your computer's screen image for an impressive presentation.

To connect to a PC or Macintosh, simply:

Terminology

PC card	This is the name of a card currently being standardized by the Japan Electronic Industry Association (JEIDA) and PCMCIA (Personal Computer Memory Card Interface Association) of the United States.
ATA card	A type of PC card. ATA was originally a type of interface between computers and fixed disk devices. The ATA card is a standard card-type recording medium.
CompactFlash	CompactFlash card is a small removable card conforming to ATA specifications. It is one-fourth the volume of a PCMCIA card.
TYPE (I, II and III)	PCMCIA 2.1 PC cards are divided into three types according to their thickness: Type I (3.3 mm), Type II (5.0 mm) and Type III (10.5 mm).
BMP	A type of image format. The standard Windows Bit Map format used for MS-DOS/Windows-compatible computers.
JPEG	A type of image format. "JPEG" is the abbreviation of Joint Photographic Experts Group. JPEG compression offers efficient data storage. The data not required for displaying the image is identified and deleted. Since the data is deleted, JPEG algorithms are said to be irreversible. This means that once the image is compressed, the decompressed image it is not the same as the original image.

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

Replacing the Lamp

After your lamp has been operating for 1500 hours (2500 hours : 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 1500 (2500 hours : 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 a full minute, 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 three lamp case screws. You could receive an electric shock.
• The projector will turn off and go into stand by mode after 1600 (2600 hours : Eco mode) hours of service. If this happens, be sure to replace the lamp. If you continue to use the lamp after 1500 hours (2500 hours : 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.

1. Loosen the two screws securing the lamp housing until the screwdriver goes into a freewheeling condition. The three screws are not removable. Remove the lamp housing by pulling out the handle.

NOTE: There is an interlock on this case to prevent the risk of electrical shock. Do not attempt to circumvent this interlock.

1. Insert a new lamp housing until the lamp housing is plugged into the socket.

CAUTION: Do not use a lamp other than the NEC replacement lamp (MT50LP). Order this from your NEC dealer.

Secure it in place with the two screws.

Be sure to tighten the screws.

1. Reattach the lamp cover.

Tighten the lamp cover screw.

Be sure to tighten the screw.

1. After you install a new lamp, select [Menu] [Projector Options] [Setup] [Page 4] [Clear Lamp Hour Meter] to reset the lamp usage hours.

NOTE: When the lamp exceeds 1600 hours (2600 hours : Eco mode) of service, the projector cannot turn on and the message is not displayed. If this happens, press the OFF or Help button on the remote control for a minimum of 10 seconds while in standby mode. When the lamp time clock is reset to zero, the STATUS indicator goes out.

Cleaning or Replacing the Filters

The air-filter sponge keeps the inside of the MultiSync MT1055/MT1050/ MT850 Projector free from dust or dirt and should be cleaned after every 100 hours of operation (more often in dusty conditions). If the filter is dirty or clogged, your projector may overheat.

CAUTION

• Turn off the power and unplug the projector before replacing the filter.
• Only clean the outside of the filter cover with a vacuum cleaner.
• Do not attempt to operate the projector without a filter cover.
• Your projector will not operate unless the filter cover is installed correctly.

To clean the air-filter:

Vacuum the filter-through the filter cover.

To replace the air-filter:

1. Remove the filter cover by pushing up on the catch of the cover until you feel it detach.

1. Reinstall the new filter cover.

NOTE: Do not detach the sponge from the filter cover. Do not wash the filter cover with soap and water. Soap and water will damage the the filter membrane. Before replacing the filter cover, remove dust and dirt from the projector cabinet. Keep out dust and during filter replacement.
