When Viewing a DVI Digital Signal:
T o project a D VI digital signal, be sure to con­nect the PC and the projector using the sup­plied DVI-D signal cable before turning on your PC or projector. Turn on the projector first and select RGB1 –D (digital) from the source menu before turning on your PC. Failure to do so may not activate the digital output of the graphics card resulting in no picture being displayed. Should this happen, restart your PC.
Do not disconnect the supplied DVI-D signal cable while the projector is running. If the sig­nal cable has been disconnected and then re-connected, an image may not be correctly displayed. Should this happen, restar t your PC.
LT156
Quando visionate un segnale digitale DVI:
Per proiettare un segnale digitale DVI, assicuratevi di collegare il PC e il proiettore utilizzando il cavo per segnale fornito DVI-D prima di accendere il vostro PC. Accendete il proiettore e selezionate come prima cosa RGB1 –D (digitale) dal menu della fonte prima di avviare il vostro PC. Un errore nel compiere ciò potrebbe non permettere l'attivazione del segnale digitale della scheda grafica facendo in modo che nessuna immagine appaia sul display . In questo caso , rinizzializzate il vostro PC.
Non scollegate il cavo per segnale fornito D VI­D mentre il proiettore è in funzione. Se il ca vo per segnale DVI-D è stato scollegato e ricollegato ulteriormente, un immagine potrebbe non apparire sul display in maniera corretta. In questo caso, rinizzializzate il vostro PC.
LT156
Beim Betrachten eines DVI-Digitalsignals:
Zum Projizieren eines DVI-Digitalsignals müssen Sie den PC und den Projektor vor dem Einschalten des PCs mit dem mitgelieferten DVI-D-Signalkabel verbinden. Schalten Sie zuerst den Projektor ein und wählen Sie RGB1-D (digital) vom Quellenmenü, bevor Sie Ihren PC einschalten. Andernfalls wird der Digital­Ausgang der Grafikkarte nicht aktiviert und dadurch kein Bild angezeigt. Starten Sie Ihren PC in einem derartigen Fall neu.
Trennen Sie das mitgelieferte DVI-D­Signalkabel nicht ab, während der Projektor in Betrieb ist. Nach dem Abtrennen und Wiederanschließen des DVI-D-Signalkabels wird das Bild möglicherweise nicht richtig angezeigt. Starten Sie Ihren PC in einem derartigen Fall neu.
LT156
Cuando visualice una señal digital DVD:
Para proyectar una señal digital DVI, asegúrese de conectar el PC al proyector utilizando el cable de señal DVI-D antes de encender su PC. Encienda el proyector primero y seleccione RGB1-D(digital) del menú de fuente antes de encender su PC. Fallos al realizar este procedimiento puede hacer que no se active la salida digital de la tarjeta de gráficos ocasionando que no se visualice ninguna imagen. Si esto sucede, reinicie su PC.
No desconecte el cable de señal DVI-D suministrado mientras que el proyector esté funcionando. Si el cable de señal DVI-D ha sido desconectado y luego conectado nuevamente, puede que no se visualice una imagen correctamente. Si esto sucede, reinicie su PC.
LT156
Lors de la projection d’un signal numérique DVI :
Lorsque vous désirez projeter un signal DVI numérique, veuillez connecter le PC au projecteur à l’aide du câble DVI-D f ourni avant d’allumer votre PC ou votre projecteur. Allumez le projecteur en premier et sélectionnez RGB1-D( numérique) du menu de source avant d’allumer votre PC. Si vous ne le faites pas, il se peut que le sig­nal numérique de sortie de la carte graphique ne soit pas activé, ce qui aurait pour conséquence un non affichage de l’image. Dans ce cas, veuillez redémarrer votre PC.
Veuillez ne pas déconnecter le câble DVI-D fourni lorsque le projecteur est en marche. Si le câble DVI-D est déconnecté puis reconnecté ensuite, l’image peut être mal affichée. Dans ce cas, veuillez redémarrer votre PC.

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. Ne v er use strong detergents or solv ents 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.
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 y ou 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.

2. INSTALLATION

This section describes how to set up your MultiSync LT156/LT155/LT154 projector and how to connect video and audio sources.

Setting up Your Projector

Your MultiSync LT156/LT155/LT154 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 3.7 feet (1.1 m) from the wall or screen. The largest the image can be is 300" (7.6 m) when the projector is about 40.1 feet (12.2 m) from the wall or screen.
