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 200-240 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 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 moment." 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 orange 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-48.

•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.

•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.

•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.

1. INTRODUCTION

Introduction to the LT158/LT157 Projector

This section introduces you to your new LT158 (XGA/DVI) / LT157 (XGA) Projector and describes the features and controls.

Congratulations on Your Purchase of The LT158/ LT157 Projector

The LT158/LT157 is one of the very best projectors available today. The LT158/LT157 enables you to project precise images up to 300 inches (measured diagonally) from your PC or Macintosh computer (desktop or notebook), VCR, DVD player, document camera, a laser disc player or PC Card Viewer.

You can use the projector on a tabletop or cart, you can use the projector to project images from behind the screen, and the projector can be permanently mounted on a ceiling*1. The remote control can be used wirelessly.

Features you’ll enjoy:

•Simple set up and operation.

•A high-performance 130 watt NSH lamp.

•The supplied wireless remote control operates the projector from the front side or rear.

•The image can be projected between 25 and 300 inches (measured diagonally).

•Keystone correction allows you to correct trapezoidal distortion so that the image is square.

•You can choose between video modes depending on your source: "normal" for a typical picture, "natural" for true color reproduction.

•The built-in PC Card Viewer allows you to start your presentation even when a PC is not available at the site.

•The "Capture" enables you to capture the current projected image.

•An image can be projected from in front or behind a screen, and the projector can even be installed on the ceiling.

•NEC Technologies’ exclusive Advanced AccuBlend intelligent pixel blending technology - an extremely accurate image compression technology - offers a crisp image with UXGA (1600 1200) resolution*2.

•Supports most IBM VGA, SVGA, XGA, SXGA/UXGA(with Advanced AccuBlend)*2, Macintosh, component signal (YCbCr / YPbPr) or any other RGB signals within a horizontal frequency range of 15 to 100 kHz and a vertical frequency range of 50 to 120 Hz. This includes NTSC, PAL, PAL-N*3, PAL-M*3, PAL60, SECAM and NTSC4.43 standard video signals.

NOTE: Composite video standards are as follows: NTSC: U.S. TV standard for video in U.S. and Canada. PAL: TV standard used in Western Europe.

PAL-N: TV standard used in Argentine, Paraguay and Uruguay. PAL-M: TV standard used in Brazil.

PAL60: TV standard used for NTSC playback on PAL TVs. SECAM: TV standard used in France and Eastern Europe. NTSC4.43: TV standard used in Middle East countries.

•The supplied remote control can be used without a cable, and you can even use the remote control and mouse adapter to operate your PC or Macintosh mouse wirelessly from across the room with the built-in remote mouse receiver.

•You can control the projector with a PC using the PC Control port*4.

•USB terminal allows USB mouse operation *5.

•The contemporary cabinet design is light, compact, easy to carry, and complements any office, boardroom or auditorium.

•Eight pointers are available for your presentation.

*1 Do not attempt to mount the projector on a ceiling yourself.

The projector must be installed by qualified technicians in order to ensure proper operation and reduce the risk of bodily injury. In addition, the ceiling must be strong enough to support the projector and the installation must be in accordance with any local building codes. Please consult your dealer for more information.

*2 A UXGA (1600 1200) and an SXGA (1280 1024) image are converted to an XGA(1024 768) crisp image with NEC technology’s Advanced AccuBlend. This applies only to analog RGB signal.

*3 LT158 only.

*4 The PC Control Utility 1.0 is required. This program is included on the supplied CD-ROM.

*5 The USB terminal meets the USB1.1 specification and accepts a USB mouse only.

Getting Started

The fastest way to get started is to take your time and do everything right the first time. Take a few minutes now to review the user’s manual. This may save you time later on. At the beginning of each section of the manual you’ll find an overview. If the section doesn’t apply, you can skip it.

2. INSTALLATION

This section describes how to set up your LT158/LT157 projector and how to connect video and audio sources.

Setting up Your Projector

Your LT158/LT157 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.

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" (0.6 m) measured diagonally when the projector is roughly 3.9 feet (1.2 m) from the wall or screen. The largest the image can be is 300" (7.6 m) when the projector is about 40.4 feet (12.3 m) from the wall or screen.

Screen and Projection Distance

The following shows the proper relative positions of the projector and screen. Refer to the table to determine the position of installation.

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.

4. MAINTENANCE

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 two lamp housing 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 housing. 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.

2.Loosen the two screws securing the lamp housing until the screwdriver goes into a freewheeling condition. The two 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.

Interlock

3.Insert a new lamp housing .

CAUTION: Do not use a lamp other than the NEC replacement lamp (LT57LP). Order this from your NEC dealer.

Secure it in place with the two screws.

Be sure to tighten the screws.

4.Reattach the lamp cover.

Tighten the lamp cover screw.

Be sure to tighten the screw.

5.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 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.

E – 48

Cleaning or Replacing the Filters

The air-filter sponge keeps the inside of the LT158/LT157 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:

When “Clean Filter” option is turned on, the “Please clean the filter” message will be displayed each time the project or is turned on after it has been used in excess of 100 hours. Should this message appear, clean the filter.

•The message can be turned on or off using the “Menu” - “Filter Clean Message” option on the Setup menu. See page E-36.

•After cleaning the filter and resetting the filter usage time to zero, the message will not be displayed.

See page E-38 for resetting the filter usage time.

Vacuum the filter-through the filter cover.
