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. Ver tical angle of installation must be between -10° and +10° when displaying an image. Placing the projector outside of this range of angles may cause excess heat transfer to the lamp and shorten its life.

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.

To Dealer or Installer:

To prevent the projector from falling, install it in a place and fasten it in a way with sufficient strength to support the combined weight of the projector (7.2 kg/15.9 lbs) and a ceiling mount for an extended period of time as well as to withstand earthquakes.

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 con-

tinues to work for 2 minutes after the projector is turned off with the POWER button).

• While the POWER and the STATUS indicators are alternately flashing.

CAUTION

To protect the Lens Shift mechanism, a hard polyurethane foam pad is attached to the lens. Before using the projector, remove the foam pad. Reattach the foam pad before shipping this projector.

Lamp Replacement

•To replace the lamp, follow all instructions provided on page E-58.

• 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 2 minutes 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 hood 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.

CAUTION: Be careful when you take a PC card out of the PC card slot because the PC card and the slot are hot during or immediately after use.

CAUTION: Do not place hands near lens opening while shifting the lens. Shifting the lens could pinch fingers or hands causing injury.

2. INSTALLATION

This section describes how to set up your GT950 projector and how to connect video and audio sources.

Setting up Your Projector

Your GT950 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.

3. Connect the supplied power cable.

4. Set up the projector.

5. Connect a PC, VCR, DVD player, or other equipment.

6. Make setting or adjustments on the projector.

Distance Chart

Standard Lens (H2.0) – (H2.4)

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 3.9 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 39.4 feet (12.0 m) from the wall or screen.

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˚F (0˚C) and 95˚F (35˚C).

• 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.

For screen sizes between 25" and 300" not indicated on the above table, use formulas below.

down, use the “Menu” and “Select” buttons on your projector cabinet or ▲▼ button on your remote control to correct the orientation. (See page E-43.)

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-43.)
