des aérosols de nettoyage du commerce qui risquent d’endommager la  
surface de cet appareil. Si l’appareil est endommagé, confier les travaux  
de réparation à un centre de service agréé NEC.  
Ce symbole a pour but de prévenir l’utilisateur de la présence  
d’une tension dangereuse, non isolée se trouvant à l’intérieur de  
l’appareil. Elle est d’une intensité suffisante pour constituer un  
risque d’électrocution. Eviter le contact avec les pièces à  
l’intérieur de cet appareil.  
Pour un fonctionnement sûr et afin d’éviter d’endommager l’appareil, lire  
attentivement et respecter les instructions suivantes.  
Ce symbole a pour but de prévenir l’utilisateur de la présence  
d’importantes instructions concernant l’entretien et le  
fonctionnement de cet appareil. Par conséquent, elles doivent  
être lues attentivement afin d’éviter des problèmes.  
Afin d’éviter tout risque d’électrocution et d’incendie:  
1. Réserver un espace libre suffisant pour la ventilation afin d’éviter une  
accumulation de chaleur interne. Ne pas couvrir les trous d’aération  
arrière ou installer l’appareil dans un coffret fermé ou sur une étagère.  
L’appareil est équipé d’ailettes de refroidissement sur le dessus. Si l’appareil  
est logé dans un coffret ou sur une étagère, s’assurer qu’il y a un espace  
libre suffisant pour la dissipation de la chaleur. Si l’appareil est posé sur un  
coffret ou une étagère, la température doit être maintenue en dessous  
de 40°C.  
AVERTISSEMENT  
AFIN DE REDUIRE LES RISQUES D’INCENDIE OU D’ELECTROCUTION, NE PAS  
EXPOSER CET APPAREIL A LA PLUIE OU A L’HUMIDITE. AUSSI, NE PAS  
UTILISER LA FICHE POLARISEE AVEC UN PROLONGATEUR OU UNE AUTRE  
PRISE DE COURANT SAUF SI CES LAMES PEUVENT ETRE INSEREES A FOND.  
NE PAS OUVRIR LE COFFRET, DES COMPOSANTS HAUTE TENSION SE  
TROUVENT A L’INTERIEUR. LAISSER A UN PERSONNEL QUALIFIE LE SOIN DE  
REPARER CET APPAREIL.  
2. Ne pas utiliser la fiche polarisée du cordon d’alimentation avec des  
prolongateurs ou des prises de courant, sauf si les lames peuvent être  
insérées à fond.  
2. Manipuler l’appareil avec soin pendant son déplacement et ne pas le  
faire tomber.  
3. Eloigner l’appareil des endroits chauds, très poussiéreux et exposés en plein soleil.  
4. Eviter que des liquides et des petits objets métalliques pénètrent à  
l’intérieur de l’appareil. En cas d’accident, débrancher l’appareil et le  
confier à un centre de service agréé NEC.  
3. Ne pas exposer à la pluie ou à l’humidité.  
4. Eviter d’endommager le cordon d’alimentation, et ne pas modifier le  
cordon d’alimentation.Ne pas poser l’appareil sur le cordon  
d’alimentation. Des dommages sur le cordon pourrait provoquer une  
électrocution ou un incendie.  
5. Débrancher l’appareil avant le nettoyage. Utiliser seulement un chiffon  
doux et un détergent doux.  
Manipuler le cordon d’alimentation avec soin et éviter de le plier  
excessivement. Un cordon endommagé peut provoquer une  
électrocution ou un incendie.  
Des aérosols et produits de nettoyage disponibles dans le commerce  
risquent d’endommager l’écran et le coffret.  
6. Ne pas empiler les unités les unes sur les autres, afin d’éviter de les  
endommager.  
5. Débrancher l’appareil pendant les tempêtes ou si l’appareil n’est pas  
utilisé pendant une longue période.  
7. Ne pas poser de liquides sur l’appareil. Si du liquide se répand dans  
l’appareil, débrancher l’appareil et le faire réparer par un centre de  
réparation agrée NEC.  
6. Ne pas ouvrir le coffret. Des composants de haute tension se trouvent à  
l’intérieur. Si l’appareil est endommagé de cette manière, la garantie  
devient caduque. De plus, il y a risque d’électrocution.  
8. Cet appareil est conçu uniquement pour une installation en intérieur. Ne  
pas utiliser cet appareil dans des conditions autres que celles initialement  
spécifiées.  
9. Ne pas utiliser l’appareil sur une surface instable.  
10.Ne pas mettre l’appareil sur fin lorsqu’il est en marche ou en train de  
mémoriser.  
7. Ne pas essayer de réparer ou entretenir l’appareil soi-même. NEC ne  
saura être tenu pour responsable pour toute blessure ou dommage causé  
par des personnes non qualifiées qui essayent de réparer ou d’ouvrir le  
couvercle arrière. Confier toute réparation à un centre de service agréé  
NEC.  
11.Reposez vos yeux périodiquement.  
Pour éviter des dommages et prolonger la durée de service de l’appareil:  
1. N’utiliser qu’une source d’alimentation de 100-120 V/220-240V 50/60 Hz  
CA. Le fait d’utiliser l’appareil en continu à des tensions de ligne  
supérieures à 100-120/220-240 Volts CA réduit sa durée de vie et risque de  
provoquer un incendie.

This section describes how to select a computer or video source and how to  
adjust the picture and sound.  
4. Turning Off The monitor.  
General Controls  
Before you turn on your MultiSync XP37 Xtra/XM37 Xtra monitor ensure that  
Press the POWER OFF button on the remote control or press the POWER  
button on the front panel.  
the computer or video source is turned on.  
1)To adjust:  
Degaussing  
1. Turn On The Monitor  
The earth's magnetic field and other magnetic sources can magnetize a color  
picture tube causing patches of impure colors. This monitor automatically  
demagnetizes the picture tube for 5 seconds each time the monitor is switched  
on. Sometimes during transportation a severe magnetic field can be  
encountered which may require demagnetizing to clear the problem. Also, if  
powered on for extended periods of time, magnetic fields can be produced by  
the CRT itself, causing color impurities. In these cases, use the DEGAUSS  
key once to demagnetize the picture tube. Pressing this key once  
demagnetizes the picture tube for 5 seconds.  
The power button is on the front panel of the monitor. By turning this switch on,  
the STANDBY/POWER indicator will turn to green and the monitor will  
become ready to use. OSM is also usable from the rear panel.  
After you press the POWER OFF button on the remote control, the monitor will  
go into its standby mode and the STANDBY/POWER indicator will glow red.  
2. Select The Computer Or Video Source  
Press the “VIDEO 1” or “VIDEO 2” (VCR, document camera, or laser disc  
player), or “RGB 1” or ” RGB 2”(computer) button on the remote control to  
display the image. Or press the button on the rear panel to select your video  
source: “VIDEO 1”, “VIDEO 2”, “RGB 1”, or “RGB 2”.  
NOTE 1: In the U.S.A. the standard video signal format is NTSC, therefore  
make sure that the AUTO or NTSC is selected on OSM system control  
menu. See page 41.  
CAUTION: Please allow a minimum of 30 minutes to elapse between uses of  
the DEGAUSS key, when not switching from mode to mode. Do not hold the  
key down continuously to avoid decreasing the life of the degauss circuitry.  
NORMAL (RASTER/VISUAL) : resets the currently selected control to the  
factory setting.

DOA Policy  
For technical support or any questions concerning the

published specifications because of defects in NECTECH factory  
materials and/or workmanship during the first 30 days from the date of  
purchase by the end user. After the 30 day period any defective  
product will be considered a warranty repair.

A product is NOT considered DOA if it is functional but the box is  
damaged or it is missing contents such as manuals, cables, etc.  
1-800-836-0655  
NECTECH reserves the right to repair rather than replace any  
product.  
Due to the size and weight of large screen presentation monitor  
products, it is preferable to solve problems on-site rather than to incur  
the expense and risk of damage in return shipping. NECís service  
policies and procedures make it as effortless as possible for you to  
receive factory authorized and trained service at your location.  
Any questions concerning service and repair policies or procedures  
can also be addressed in writing to:
