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.
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.
Installation
1. For best results, use your projector in a darkened room.
b. The projector must be installed by qualified NEC service personnel.
2. Place the projector on a flat, level surface in a dry area away from dust and
moisture.
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.
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.
2. Handle the power cable carefully and avoid excessive bending. A damaged
cord can cause electric shock or fire.
6. Do not place heavy objects on top of the projector.
3. If the projector is not to be used for an extended period of time, disconnect the
plug from the power outlet.
Cleaning
Fire and Shock Precautions
1. Unplug the projector before cleaning.
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. 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.
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.
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.
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.
• 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.

4. La fumée, la vapeur et l’exposition aux rayons directs du soleil risquent de
détériorer sérieusement les composantes internes.
3. Si le projecteur n’est pas utilisé pendant une période prolongée, retirer la fiche
de la prise secteur.
5. Eviter des manipulations brusques lors du déplacement du projecteur, car un
choc violent pourrait endommager les composantes internes.
Nettoyage
6. Ne pas deposer d’objets lourds sur le dessus du projecteur.
1. Débrancher le projecteur de la prise d’alimentation avant le nettoyage.
7. Lors de l’installation du projecteur au plafond, respecter les instructions
suivantes.
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.
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.
3. Utiliser un appareil diffuseur chauffant ou du papier de nettoyage de lentille
disponible dans le commerce pour nettoyer la lentille.
Alimentation
Ne pas frapper ou rayer la surface de la lentille, car des défauts risquent de se
produire sur la surface de la lentille.
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.
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.
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.
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.
• 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.
• 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.
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.

projector.
When using a Macintosh with the LT80, set the DIP switch of the supplied monitor adapter according to your resolution. After setting, restart your
Macintosh.
See the following pages for setting of the DIP switch.
• When using with a Macintosh, VGA/SVGA (800
ן 600) is recommended if your Macintosh supports this mode. •
When using with a Macintosh PowerBook, output may not be set to 800
ן 600 unless “mirroring” is off on your PowerBook. Refer to owner’s manual supplied with your Macintosh computer for mirroring.

This section describes the simple maintenance procedures you should follow
to replace the lamp and replace the batteries in the remote control.
Replacing The Lamp
After your lamp has been operating for 1000 hours or longer, the “sta-
tus” light in the cabinet will turn red. Even though the lamp may still be
working, replace it at 1000 hours to maintain optimal projector perform-
ance.
Step 3
Step 4
CAUTION
Lamp cover
• DO NOT TOUCH THE LAMP immediately after it has been used. It will
be extremely hot. Allow at least one hour for the lamp to cool before
handling.
• DO NOT REMOVE ANY SCREWS except the lamp cover set screw
and two lamp case screws. You could receive an electric shock.
• Turn off the main power to the projector and disconnect the power cord.
Allow at least one hour for the lamp to cool.
• The projector will turn off and go into stand by mode after 1100 hours of
service. If this happens, be sure to replace the lamp. 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.
Lamp housing

CAUTION: Do not use a lamp other than the NEC replacement lamp.
Order this from your NEC dealer using your projector's model num-
ber.
5. Remove the three screws for the lamp housing.
(There is an interlock on the lamp housing to prevent the risk of electri-
cal shock. Do not attempt to circumvent this interlock.)
6. Holding the handle, pull the lamp housing forward and take it off.
7. Install the new lamp housing and fasten with the three screws.
8. Fasten the three screws for the lamp housing.

mote controller and hold it down for at least ten seconds.
NOTE: If resetting the lamp clock back to zero after 1100 hours of
service, press the "Power Off" (not "Power On") button on the remote
control for ten seconds .
