Warnings and Safety Precaution

The NEC MultiSync Multimedia monitors XP37 Xtra and XM37 Xtra are de­signed and manufactured to provide long, trouble-free service. No mainte­nance other than cleaning is required. Use a soft cloth and if necessary, mild
detergent. Do not use commercial spray cleaners which may damage the
surface. In case of damage, arrange for repairs at an authorized NEC Ser­vice Center.

For operating safety and to avoid damage to the unit, read carefully and
observe the following instructions.

To avoid shock and fire hazards:

1. Provide adequate space for ventilation to avoid internal heat build-up.
Do not cover rear vents or install in a closed cabinet or shelves.
The unit is equipped with cooling fans on the top. If you enclose the unit in
a cabinet or rack, be sure there is adequate space at the top and rear of
the unit to allow heated air to rise and escape. A cabinet or shelves in
which the unit is placed must be maintained below 40°C

2. Do not use the power cord polarized plug with extension cords or outlets
unless the prongs can be completely inserted.

3. Do not expose unit to rain or moisture.

4. Avoid damage to the power cord, and do not attempt to modify the
power cord. Do not place the unit on the power cord. Damage to the
cord may cause shock or fire.

Handle the power cord carefully and avoid excessive bending. A
damaged cord can cause electric shock or fire.

5. Unplug unit during electrical storms or if unit will not be used over a long
period.

6. Do not open the cabinet which has potentially dangerous high voltage

components inside. If the unit is damaged in this way the warranty will be
void. Moreover, there is a serious risk of electric shock.

7. Do not attempt to service or repair the unit. NEC is not liable for any bodily
harm or damage caused if unqualified persons attempt service or open
the back cover. Refer all service to authorized NEC Service Centers.

To avoid damage and prolong operating life:

1. Use only with 100-120V/220-240V 50/60Hz AC power supply. Continued
operation at line voltages other than 100-120V/220-240 Volts
shorten the life of the unit, and might even cause a fire hazard.

2. Handle the unit carefully when moving and do not drop.

3. Locate set away from heat, excessive dust, and direct sunlight.

4. Protect the inside of the unit from liquids and small metal objects. In case
of accident, unplug the unit and have it serviced by an authorized NEC
Service Center.

5. Unplug unit before cleaning. Use only a soft cloth and mild detergent.

Mises en garde et précautions de sécurité

Les moniteurs MultiSync Multimédia XP37 Xtra et XM37 Xtra 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.

Pour un fonctionnement sûr et afin d’éviter d’endommager l’appareil, lire
attentivement et respecter les instructions suivantes.

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.

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.Ne pas poser l’appareil sur le cordon
d’alimentation. Des dommages sur le cordon pourrait provoquer une
électrocution ou un incendie.

Manipuler le cordon d’alimentation avec soin et éviter de le plier
excessivement. Un cordon endommagé peut provoquer une
électrocution ou un incendie.

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 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.

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.
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

endommager.

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.

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.

11.Reposez vos yeux périodiquement.

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.
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.

Using OSM Controls

NEC's OSM, or On-Screen Manager, System offers the ultimate form of
monitor controls. Keys on the remote control unit or front panel allow you to
easily navigate through menus and adjust controls.
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.

OSM keys on the remote control unit function as follows:
PROCEED : accesses the OSM controls. When an

adjustment item is selected, a press of this
button returns to its icon selection screen.

-in the color temperature: proceeds to the
control for RGB gain and bias.

EXIT : exits the OSM controls.

-in the RGB gain and bias: return to the color
temperature screen.

POSITION CONTROL up/down : selects one of the control items.
POSITION CONTROL-/+ : increase or decrease the settings level.

: selects a group icon at top of the OSM screen

when any one of them is highlighted without
any specific control selected.

NORMAL (RASTER/VISUAL) : resets the currently selected control to the

factory setting.

-when a specific group icon is highlighted, this
key resets all the specific controls settings or all
the settings.

-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.

Service and Support Policies

NEC Technologies is committed to providing the highest quality service
and support for your MultiSync presentation monitor. A customer
service group that is dedicated to the support of this product line is
available to provide a single point of contact for technical support,
trouble shooting, service and repair issues.

Please address all questions concerning the following subjects to the
phone number listed below:

For technical support or any questions concerning the
operation of this product.

To arrange for on-site repair service during the warranty period
or after its expiration.

For the location of your nearest authorized NEC service center.
To report a DOA product and verify its status for return

authorization.

1-800-836-0655

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.

On-site Service/Repair Policy

NEC offers on-site service and repair for all of our MultiSync presentation
monitor products of 37" and larger screen size. Warranty repair is
provided by our service-authorized Visual Systems Division Dealers and
network of factory-trained independent service providers. If you are
experiencing a problem with your monitor, please contact the
authorized NEC Visual Systems Division dealer from which it was
purchased. If this is a reseller who is unable to provide service, call NEC
directly at 1-800-836-0655.

DOA Policy

A product is considered DOA if it fails to function according to current
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.

NECTECH reserves the right to repair rather than replace any
product.

Eligibility/Return for Exchange Procedure

If a product is suspected of being DOA, customers must call NECTECH
VSD Technical Support. A representative will assist in making the
product fully functional or verify it as a DOA.

VSD Technical Support 1-800-836-0655
NEC technical support will provide a procedure for repair instead of
exchange.

If the product is determined to be DOA, the Technical Support
Representative will request the following information in order to issue a
Material Return Authorization (MRA) number:

Product model number
Serial number
A complete description of the problem

If approved, an MRA number and return address will be issued. All
product to be returned must be shipped freight pre-paid in its original
carton to a designated NECTECH facility. The customer assumes the
risk of loss. The defective product must be received by NECTECH within
21 calendar days from the date the MRA was issued.

Any questions concerning service and repair policies or procedures
can also be addressed in writing to:
