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
• 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.

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.

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.
3. Si le projecteur n’estpasutilisépendant une période prolongée, retirerlafiche
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.
7
Remplacement de la lampe
• 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
DLP.
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.

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.
4. Move the projector left or right to center the image horizontally on
the screen. (A)
5. To center the image vertically (B).

6. Fine tune the image’s vertical position by adjusting the front feet of
the projector.
Adjustment method
A. Start with the adjustable feet screwed in the locked position.
B. Screw down the feet until proper angle is reached.
Note: Adjust feet so that lens surface is parallel to the screen. If you use
the projector with the screen tilted, the picture will be distorted.
7. Adjust the size of the image using the zoom ring lever on the lens.
Note: The set up angle of the projector should not exceed 15 degrees,
otherwise lamp life could decrease dramatically.

Remote Control Guideline
1. Plug the serial cable with the remote mouse receiver into your computer's mouse port and restart your computer to gain remote mouse
control.
2. When using the remote control's built-in infrared mouse on a laptop computer, the laptop's mouse, trackball or trackpad will be disabled.
Disconnect the infrared receiver and restart your computer to regain trackball or trackpad mouse control.
3. If the screen goes blank while using your remote control, it may be the result of the computer's screen-saver or power management
software. If you accidentally hit the OFF button on the remote control, wait one full minute and then press the ON button to resume.
