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 turn off the main power or unplug the power cable from the wall outlet under any one of the following circumstances. 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 cooling fan continues to work for 60 seconds after the projector 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 sustained on the surface of the LCD panel.

If this should happen, continue to use your projector. The static background from previous images will disappear.

Lamp Replacement

• To replace the lamp, follow all instructions provided on page E-36.
• 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 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.

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.

Introduction to the VT45 Projector

This section introduces you to your new VT45 (SVGA) Projector and describes the features and controls.

Congratulations on Your Purchase of The VT45 Projector

The VT45 is one of the very best projectors available today. The VT45 enables you to project precise images up to 300 inches across (measured diagonally) from your PC or Macintosh computer (desktop or notebook), VCR, DVD player, document camera, or even a laser disc player.

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.
• Eco Mode, two selectable options (120 watt for Eco 1 and 110 watt for Eco 2) that allow users to reduce the projector's light output, resulting in a doubling (Eco 2) of usable lamp life and decreased lamp replacement costs throughout the projector's life.
• A high-performance 130 watt NSH lamp.
• Manual horizontal (max 1/3 of width) and vertical (max 1/2 of height) lens shift provides simple imaging positioning.
• The lamp life can be extended up to 2000 hours by using the Eco 2 mode.
• The supplied wireless remote control that operates the projector from the front side or rear.
• Manual zoom control enables you to adjust the image between 25 (0.63 m) and 300 inches (7.6 m) (measured diagonally).
• Keystone correction allows you to correct trapezoidal distortion so that the image is square.
• Color Management feature includes Gamma Correction, White Balance, and Color Correction that provides natural and true color reproduction.
• You can choose between video modes depending on your source: “normal” for a typical picture, “natural” for true color reproduction.
• 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 SXGA (1280 × 1024) resolution ^*2 .

• Supports most IBM VGA, SVGA, XGA* ^2 , SXGA* ^2 , Macintosh, component signal (YCbCr / YPbPr) or any other RGB signals within a horizontal frequency range of 15 to 80 kHz and a vertical frequency range of 50 to 100 Hz. This includes NTSC, PAL, PAL60, SECAM and NTSC4.43 standard video signals.

• The supplied remote control can be used without a cable.

• You can control the projector with a PC using the PC Control port.
• The contemporary cabinet design is light, compact, easy to carry, and complements any office, boardroom or auditorium.

*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 An XGA image (1024×768) and SXGA image (1280×1024) are converted into an 800×600 crisp image with NEC technology's Advanced AccuBlend.

2. INSTALLATION

This section describes how to set up your VT45 projector and how to connect video and audio sources.

Setting up Your Projector

Your VT45 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" (0.64 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 39.3 feet (12.0 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 side of the projector to release the Front Adjustable foot.

(There is approximately 10 degrees of up and down adjustment for the front of the projector.)

Using the Lens Shift

1. Grip the lens shift lever on the top and bottom.
2. Hold the lever to move the lens vertically or horizontally.

NOTE: It may not be possible to obtain maximum shift range due to the rounded off area near the edge of the lens. The amount of lens shift adjustable range depends on the direction that the lens is shifted. See diagram below.
