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 installing the projector on the ceiling: a. The ceiling must be strong enough to support the projector and the installation must be in accordance with any local building codes.
b. The projector must be installed by qualified NEC service personnel.
Power Supply
1. The projector is designed to operate on a power supply of 100-120 or 220-240
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.
Lamp Replacement
• Perform lamp replacement in accordance with the instructions on page 77.
• Be sure to replace the lamp when the Status light comes on. If you continue to use the lamp after 1000 hours 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.
• Allow a minimum of ONE minute to elapse between turning the lamp off and on. High voltage is applied to the lamp immediately when the power is turned on. Therefore turning the power off and quickly back on may shorten the life of your lamp and result in damage to your projector.
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
(10cm) 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 project. If something should fall into your projector, disconnect it immediately and have the object removed by a qualified NEC service person.
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.
• 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.

Importantes précautions de sécurité
Les points suivants sont des précautions de sécurité importantes destinées à garantir une longue durée de service du projecteur et afin d’éviter un incendie et des risques d’électrocution. S’assurer de lire attentivement ces précautions de sécurité et respecter tous les avertissements décrits ci-dessous.
Installation
1. Pour un fonctionnement optimal, utiliser le projecteur dans une pièce sombre.
2. Placer le projecteur sur une surface à niveau et dans un endroit sec exempt de poussières et d’humidité.
3. Ne pas placer le projecteur en plein soleil, près d’appareils ménagers ou d’autres appareils de chauffage.
6
4. La fumée, la vapeur et l’exposition aux rayons directs du soleil risquent de détériorer sérieusement les composantes internes.
5. Eviter des manipulations brusques lors du déplacement du projecteur, car un choc violent pourrait endommager les composantes internes.
6. Ne pas deposer d’objets lourds sur le dessus du projecteur.
7. Lors de l’installation du projecteur au plafond, respecter les instructions suivantes.
a. Le plafond doit être suffisamment solide pour supporter le poids du projecteur et il doit être installé selon les codes de construction locaux.
b. Le projecteur doit être installé par un personnel qualifié.
Alimentation
1. Le projecteur est conçu pour fonctionner à 100-120 ou 220-240VCA 50/
60Hz. S’assurer que la tension d’alimentation locale satisfait cette exigence avant d’utiliser le projecteur.
2. Manipuler le câble d’alimentation avec précaution et éviter de le plier excessivement. Un cordon endommagé risque de provoquer une
électrocution ou un incendie.
7
3. Si le projecteur n’est pas utilisé pendant une période prolongée, retirer la fiche de la prise secteur.
Nettoyage
1. Débrancher le projecteur de la prise d’alimentation avant le nettoyage.
2. Nettoyer régulièrement le coffret avec un chiffon doux. S’il y a des taches tenaces, utiliser une solution d’un détergent doux. Ne jamais utiliser de détergents puissants ou des solvants, tel que l’alcool ou un diluant pour nettoyer le projecteur.
3. Utiliser un appareil diffuseur chauffant ou du papier de nettoyage de lentille disponible dans le commerce pour nettoyer la lentille.
Ne pas frapper ou rayer la surface de la lentille, car des défauts risquent de se produire sur la surface de la lentille.
Remplacement de la lampe
• Effectuer le remplacement de la lampe suivant les instructions de la page 81.
• Assurez-vous de bien remplacer la lampe lorsque le voyant d’usure s’allume. Si vous continuez d’utiliser la lampe après 1000 heures d’utilisation, l’ampoule peut se briser et des brisures de verre peuvent être
éparpillées dans le compartiment de la lampe. Ne les touchez pas car elles peuvent vous blesser. Dans ce cas, contactez votre revendeur NEC afin de procéder au remplacement de la lampe.
• Attendez minimum UNE minute après avoir éteint la lampe avant de la rallumer. Une haute tension est immédiatement appliquée à la lampe quand celle-ci est mise sous tension. Par conséquent, éteindre, puis tout de suite rallumer peut abréger la vie de votre lampe et endommager votre projecteur.
Précautions pour éviter un incendie ou une électrocution
1. Une ventilation appropriée doit être assurée afin d’éviter une accumulation de chaleur à l’intérieur du projecteur. S’assurer que les trous de ventilation ne sont pas obstrués. Laisser un espace d’au moins 10 cm (quatre pouces) entre le projecteur et les murs.
2. Eviter que des objets étrangers, des agrafes, des clous et du papier, par exemple, pénètrent à l’intérieur du projecteur. Ne pas essayer de récupérer ces objets soi-même ou ne pas insérer des objets métalliques, des fils et des tourne-vis, par exemple à l’intérieur du projecteur. Si un objet tombe à l’intérieur du projecteur, le débrancher immédiatement et contacter un dépanneur qualifié pour retirer l’objet.
3. Ne pas placer des liquides sur le dessus du projecteur.
• Ne regardez pas à l’intérieur de l’objectif lorsque le projecteur est en marche. Vous risquez de vous blesser gravement aux yeux.
• Ne regardez pas à l’intérieur de la flèche laser lorsque celle-ci est en marche et ne dirigez pas le rayon laser sur une autre personne. Vous risquez de provoquer ue blessure grave.

This section describes how to set up your MultiSync LT100 projector and how to connect video and audio sources.
Setting Up Your MultiSync LT100 Projector
Your MultiSync LT100 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.
Carrying The Projector Always carry your projector by the handle. Ensure
that the power cord 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 24"
(0.61 m) measured diagonally when the projector is roughly 4 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 40.35 feet (12.3 m) from the wall or screen.
