Mises en garde et précautions de sécurité  
Les moniteurs MultiSync Multimédia XP37 Plus et XM37 Plus de NEC ont été  
conçus et fabriqués pour assurer une longue durée de service sans  
problèmes. Aucun entretien à l’exception du nettoyage n’est nécessaire.  
Utiliser un chiffon doux et un détergent doux, si nécessaire. Ne pas utiliser  
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.  
5. Débrancher l’appareil pendant les tempêtes ou si l’appareil n’est pas  
utilisé pendant une longue période.  
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.  
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.  
Pour un fonctionnement sûr et afin d’éviter d’endommager l’appareil, lire  
attentivement et respecter les instructions suivantes.  
Pour éviter des dommages et prolonger la durée de service de l’appareil:  
Afin d’éviter tout risque d’électrocution et d’incendie:  
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.  
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.  
5. Débrancher l’appareil avant le nettoyage. Utiliser seulement un chiffon  
doux et un détergent doux.  
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.  
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.  
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.  
Des aérosols et produits de nettoyage disponibles dans le commerce  
risquent d’endommager l’écran et le coffret.

Before you turn on your MultiSync XP37 Plus/XM37 Plus 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

Using OSM Controls  
NEC's new OSM, or On-Screen Manager, System offers the ultimate form of  
monitor controls. Keys on the remote control unit or rear panel allow you to  
easily navigate through menus and adjust controls.  
-when a specific group icon is highlighted, this  
key resets all the specific controls settings or all  
the settings.  
OSM controls include extended controls such as Brightness, Contrast, Size,  
Position, Pin cushion, Keystone, Vertical Linearity, Scan Select and other  
OSM utilities. Adjustments are saved instantly. The currently addressed  
control can be reset to factory settings by pressing the NORMAL key.  
-when a specific control is selected: this key  
resets the selected adjustments.  
NOTE: The NORMAL function is not valid in  
the OSM Turn Off Time, Language Select  
menus, and Volume Control.

Horizontal sync width should exceed 0.9 µsec.  
Horizontal back porch should exceed 2.0 µsec at sync on green and 1.2 µsec at others except when at 15KHz.  
Horizontal blanking should exceed: 7.0µse at fH 15.75kHz, 3.3µsec at 30 kHz<fH<50kHz, 2.9µusec at 51kHz<fH<80kHz,  
and 2.7µsec at 81kHz<fH<95kHz  
Vertical sync duty should be 0.2 to 10%.  
Vertical sync width should exceed 40 µsec or 2 horizontal lines.  
Vertical sync width plus back porch should exceed 0.4 msec.  
Interlaced signals are not recommended.  
Interlaced signals with composite sync may not be displayed.

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:
