CAUTION  
Important Safeguards  
Do not unplug the power cable from the wall outlet under any one  
of the following circumstances. Doing so can cause damage to  
the projector:  
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.  
• While the message "Please wait a moment." appears. This message  
will be displayed after the projector is turned off.  
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.  
• Immediately after the power cable is plugged into the wall outlet (the  
POWER indicator has not changed to a steady orange glow).  
• Immediately after the cooling fan stops working (The cooling fan con-  
tinues to work for three minutes after the projector is turned off with  
the POWER button).  
• While the POWER and the STATUS indicators are alternately flashing.  
4. Exposure to direct sunlight, smoke or steam can harm internal com-  
ponents.  
5. Handle your projector carefully. Dropping or jarring can damage in-  
ternal 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.  
CAUTION  
• Do not put the projector on its side when the lamp is turned on.  
Doing so may cause damage to the projector.  
• Before shipping this projector, remove the lens and attach the lens  
hood cap.  
The Lens Shift mechanism may encounter damage caused by improper  
handling during transportation.  
Lamp Replacement  
• To replace the lamp, follow all instructions provided on page E-52.  
• 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.  
To Dealer or Installer:  
To prevent the projector from falling, install it in a place and fasten it in  
a way with sufficient strength to support the combined weight (17.0 kg/  
37.5 lbs) of the projector (12.8 kg/28.3 lbs), the lens (2.0 kg/4.4 lbs)  
and the ceiling mount(2.1 kg/4.7 lbs) for an extended period of time as  
well as to withstand earthquakes.  
• Allow a minimum of three minutes to elapse after turning off the  
projector.Then disconnect the power cable and allow 60 minutes to  
cool the projector before replacing the lamp.  
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.  
Fire and Shock Precautions  
1. Ensure that there is sufficient ventilation and that vents are unob-  
structed 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 re-  
moved by a qualified NEC service personnel.  
3. Do not place any liquids on top of your projector.  
4. When using a LAN cable:  
For safety, do not connect to the connector for peripheral device  
wiring that might have excessive Voltage.  
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.  
CAUTION  
• 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, there-  
fore 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 hood 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.

électrique de 100-120 ou 200-240 V 50/60 Hz. Assurez-vous que  
votre alimentation correspond à ces critères avant d’essayer d’utiliser  
votre projecteur.  
2. Manipulez le câble d’alimentation avec précaution et évitez de  
l’entortiller. Tout câble endommagé peut provoquer une décharge  
électrique ou un incendie.  
3. Si le projecteur ne doit pas être utilisé pendant longtemps,  
débranchez la prise de la source d’alimentation.  
Avertissements  
• Ne regardez pas à l’intérieur de l’objectif lorsque le projecteur est  
en marche. Vous risquez de vous blesser gravement aux yeux.  
• Maintenez tout ce qui s’apparente à une loupe en dehors du faisceau  
lumineux du projecteur. La lumière projetée par l’objectif est très  
puissante, de sorte que tout objet en opposition pourrait dévier le  
faisceau provenant de l’objectif, ce qui pourrait avoir des  
conséquences imprévues telles qu’un incendie ou une lésion  
occulaire.  
Nettoyage  
1. Débranchez le projecteur avant de procéder au nettoyage.  
2. Nettoyez régulièrement le coffret avec un chiffon humide. Si celui-ci  
est très sale, utilisez un détergent doux. N’utilisez jamais de  
détergents puissants, de l’alcool ou d’autres solvants.  
3. Utilisez un ventilateur ou un papier à objectif pour nettoyer l’objectif  
et faîtes attention de ne pas rayer ou d’abîmer l’objectif.  
• Ne bouchez pas l’objectif avec son couvercle fourni lorsque le  
projecteur est allumé. Faire cela pourrait faire fondre le couvercle et  
peut-être brûler vos mains à cause de la châleur émise par le faisceau  
lumineux.  
Information importante  
Ne pas débrancher le câble d’alimentation de la prise du secteur dans  
les circonstances suivantes car cela risque d’endommager le projecteur:  
* Lorsque le message "Veuillez patientez un instant" apparaît. Ce mes-  
sage sera affiché après que le projecteur soit éteint.  
* Immédiatement après que le cordon d’alimentation électrique ait été  
branché sur la prise du mur (l’indicateur POWER n’est pas encore  
devenu orange).  
* Immédiatement après que le ventilateur de refroidissement de soit arrêté  
de fonctionner (le ventilateur de refroidissement continue à fonctionner  
pendant trois minutes après l’extinction du projecteur grâce à  
l’interrupteur POWER OFF).  
* Lorsque les indicateurs POWER (alimentation électrique) et STATUS  
(état) clignotent alternativement.  
ATTETION  
• Ne pas placer le projecteur sur le côté lorsque la lampe est allumée,  
sinon le projecteur risque d’être endommagé.  
• Avant d’expedier ce projecteur, veuillez démonter l’objectif et fixer le  
bouchon d’objectif.

Remote Control Precautions  
Operating Range for Wireless Remote Control  
The infrared signal operates by line-of-sight up to a distance of ap-  
proximately 7m (20 feet) and a 60 degree angle of the remote sensor.  
The projector will not function if there are objects between the remote  
sensor and the remote control or if strong light falls on the remote  
sensor. Weak batteries will also prevent the projector from operating  
properly.  
• The remote control system may not function when direct sunlight or  
strong illumination strikes the remote control sensor of the main unit,  
or when there is an obstacle in the path.  
• When remote control buttons are pressed and held, projector’s func-  
tion keys may not operate.  
• Do not subject to strong shock.  
• Do not allow water or other liquid to splash on the remote control. If  
the remote control gets wet, wipe it dry immediately.  
• Avoid exposure to heat and steam.  
Remote sensors on the projector cabinet  
• Remove the batteries from the remote control when the remote con-  
trol is not going to be used for a long period.

lens. The lens can be shifted within the shaded area as shown using  
the normal projection position as a starting point.  
Lens Shift Adjustable Range  
NOTE: Lens shift feature is not available on GT10RL(fixed lens).  
Maximum Possible Range for GT19ZL/GT34ZL (GT13ZL):  
Up: 0.5 V (0.43V)  
Down: 0.5 V (0.43V)

Optional Lens Installation  
This section describes how to install the lens.  
Before installation  
* Determine the optional lens to be used to obtain a desired projection distance. There are four optional lenses available:  
GT10RL (Fixed short throw lens)  
GT19ZL, GT13ZL and GT34ZL (Zoom lens)  
* Press the power button (ON/STAND BY) on the projector or POWER OFF button on the remote control, wait three minutes for the cooling fan to stop, then  
disconnect the power cable.  
Check that the projector has cooled off sufficiently before proceeding.  
CAUTION  
* The projector and lens contain high-precision parts. Do not induce shock to the projector or the lens.  
* Do not touch the lens surface. Doing so can degrade the optical performance.  
Preparation: Tools needed for installation:  
A hexagonal driver and dust-protective sheets are supplied with the optional lens.  
1. Remove the lens hood cap and lens hood.  
1 Press and hold the catches on both ends of the lens hood cap, and 2 then remove it.  
3 Loosen the 4 screws on the lens hood using the hexagonal driver until the hexagonal driver goes into a freewheeling condition and 4 remove  
the lens hood. The 4 screws are not removable.

Pour remplacer le filtre à air:  
Nettoyage ou remplacement du filtre  
Le coussin éponge du filtre à air maintient l’intérieur du projecteur  
GT2150 à l’abri de la poussière ou de la saleté et doit être nettoyé  
toutes les 100 heures d’utilisation (plus souvent dans les endroits  
poussiéreux). Si le filtre est sale ou bouché, le projecteur risque de  
surchauffer.  
1. Retirez-vous le le filtre en poussant au-dessus sur la prise.  
PRECAUTION  
• Coupez l’alimentation et débranchez le projecteur avant de remplacer  
le filtre.  
• Nettoyez uniquement le couvercle extérieur du filtre avec un aspirateur.  
• N’essayez pas de faire fonctionner le projecteur sans filtre.  
• Votre projecteur à affichage à cristaux liquides ne fonctionnera pas  
tant que le filtre ne sera pas installé correctement.

NOTE: Pins 1, 4, 6 and 9 are used inside the projector.  
NOTE:: Jumper “Request to Send” and “Clear to Send” together on both ends  
of the cable to simplify cable connection.  
Gravity Stack  
Up to two units can be gravity stacked without external support. In some cases, however, two images will not align on the  
screen correctly. This will become more apparent when displaying small text and detailed graphics.  
1. Note : Gravity Stacking Two GT2150 Projectors  
The optional lenses for GT2150 have different geometrical distortions in wide zoom and tele. Select the best zoom position for  
stacking where the geometrical distortion is as small as possible. The recommended throw distances are as follows:

• Lens position  
Horizontal lens position must be as close to the center of the lens opening as possible.  
2. Note: Gravity Stacking in link mode  
A distribution amplifier is recommended for Gravity stacking in link mode to distribute one input source to two projectors.  
3. Note: Gravity stacking in link mode without a distribution amplifier  
In this configuration, horizontal position of each projector will need to be adjusted before enabling Link mode.This adjustment will  
prevent image alignment.
