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 techni-
cians in order to ensure proper operation and reduce the risk of bodily injury.
c. In addition, the ceiling must be strong enough to sup-
port 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.
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.
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.
E–3
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 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.

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 youll 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.

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.
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 E-33.)
Reflecting the Image
Using a mirror to reflect your projectors image enables you to enjoy a much larger image. Contact your NEC dealer if you need a mirror. If youre 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-33.)

4. MAINTENANCE
This section describes the simple maintenance procedures you should follow to replace the lamp, clean the filters, and replace the batteries in the remote control.
Replacing the Lamp
After your lamp has been operating for 1000 hours (up to 2000 hours in Eco 2 mode and up to 1500 hours in Eco 1 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 1000 (up to 2000 hours in Eco 2 mode and up to 1500 hours in Eco 1 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 60 seconds, 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 case screws. You could re­ceive an electric shock. The projector will turn off and go into stand by mode after
1100 (up to 2100 hours in Eco 2 mode and up to 1600 hours in Eco 1 mode) hours of service. If this happens, be sure to replace the lamp. If you continue to use the lamp after 1100 hours (up to 2100 hours in Eco 2 mode and up to 1600 hours in Eco 1 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.
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 until the lamp housing is plugged into the socket.
CAUTION
Do not use a lamp other than the NEC replacement lamp (VT45LP). 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.
E–36
5. After you install a new lamp, select [Advanced Menu] [Projector Options]→[Setup]→[Page 4][Clear Lamp Hour Meter] to reset the lamp usage hours.
NOTE: When the lamp exceeds 1100 hours (up to 2100 hours in Eco 2 mode and up to 1600 hours in Eco 1 mode) of service, the projector cannot turn on and the menu 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.
Cleaning or Replacing the Filters
The air-filter sponge keeps the inside of the VT45 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 filters message will be displayed each time the projector is turned on after it has been used in excess of 100 hours. Should this message appear, clean the filters.
The message can be turned on or off using the Menu - Fil­ter Clean Message option on the Setup menu. See page E-
33.
After cleaning the filters and resetting the filter usage time back to zero, the message will not be displayed. See page E-35 for resetting the filter usage time.
Vacuum the filter-through the filter cover.

2. 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.
NOTE: When you replace the lamp, it is also wise to replace the filters. The filters come in the same package with your replace­ment lamp.
NOTE: A mix-up between the two filter covers can cause a dam­age to the projector. The front and the side filter covers appear to be the same shape, but they are not interchangeable with each other.
