• Rest your eyes periodically by focusing on an object at least5 feet away. Blink often.
• Position the monitor at a 90° angle to windows and other light sources to minimize glare and reflections.
• Clean the LCD monitor surface with a lint-free, non-abrasive cloth. Avoid using any cleaning solution or glass cleaner!
• Adjust the monitor’s brightness, contrast and sharpness controls to enhance readability.
• Avoid displaying fixed patterns on the monitor for long periods of time to avoid image persistence (after image
effects).
• Get regular eye checkups.
Ergonomics
To realize the maximum ergonomic benefits, we recommend
the following:
• Use the preset Size and Position controls with standard signals.
• Use the preset Color Setting.
• Use non-interlaced signals.
• Do not use primary color blue on a dark background, as it is difficult to see and may produce eye fatigue due to
insufficient contrast.
Cleaning the LCD Panel
• When the liquid crystal panel is dusty, gently wipe with asoft cloth.
• Please do not rub the LCD panel with hard material.
• Please do not apply pressure to the LCD surface.
• Please do not use OA cleaner as it will cause deterioration or discolor on the LCD surface.
Cleaning the Cabinet
• Unplug the power supply
• Gently wipe the cabinet with a soft cloth
• To clean the cabinet, dampen the cloth with a neutraldetergent and water, wipe the cabinet and follow with a dry
cloth.
NOTE: The surface of the cabinet is composed of many types
of plastic. DO NOT clean with benzene thinner, alkaline
detergent, alcoholic system detergent, glass cleaner,
wax, polish cleaner, soap powder, or insecticide.
Rubber or vinyl should not be in contact with the cabinet
for an extended period of time. These types of fluids
and materials can cause the paint to deteriorate, crack
or peel.

For properinstallation it is strongly recommended to use a trained,NEC authorized service person. Failure to follow NECstandard mounting procedures could result in damage to theequipment or injury to the user or installer. Product warrantydoes not cover damage caused by improper installation.Failure to follow these recommendations could result invoiding the warranty.
Mounting
DO NOT mount the monitor yourself. Please ask dealer.
For proper installation it is strongly recommended to use a
trained, qualified technician. Please inspect the location
where the unit is to be mounted. Mounting on wall or ceiling
is the customer’s responsibility. Not all walls or ceilings are
capable of supporting the weight of the unit. Product
warranty does not cover damage caused by improper
installation, remodelling, or natural disasters. Failure to
comply with these recommendations could result in voiding
the warranty.
DO NOT block ventilated openings with mounting
accessories or other accessories.
For NEC Qualified Personnel:
To insure safe installation, use two or more brackets to
mount the unit. Mount the unit to at least two points on the
installation location.
Please note the following when mounting
on wall or ceiling
• When using mounting accessories other than those that are NEC approved, they must comply with the VESA-
compatible (FDMlv1) mounting method.
• NEC strongly recommends using size M6 screws
(9-10 mm + thickness
of bracket and washer in
length). If using screws
longer than 9-10 mm,
check the depth of the hole.
(Recommended Fasten
Force: 310 - 410 N•cm)
NEC recommends mounting
interfaces that comply
with UL1678 standard in
North America.
• Prior to mounting, inspect the installation location to insure that it is strong enough to support the weight of
the unit so that the unit will be safe from harm.
• Refer to the instructions included with the mounting equipment for detailed information.
Weight of LCD assembly:
- MultiSync V321: 14.3 kg/31.5 lbs
- MultiSync V421: 20.5 kg/45.2 lbs
- MultiSync V461: 24.0 kg/52.9 lbs
Installation
Mounting location
• The ceiling and wall must be strong enough to supportthe monitor and mounting accessories.
• DO NOT install in locations where a door or gate can hit the unit.
• DO NOT install in areas where the unit will be subjected to strong vibrations and dust.
• DO NOT install near where the main power supply enters the building.
• Do not install where people can easily grab and hang onto the unit or the mounting apparatus.
• When mounting in a recessed area, as in a wall, leave at least 4 inches (10cm) of space between the monitor and
the wall for proper ventilation.
• Allow adequate ventilation or provide air conditioning around the monitor, so that heat can properly dissipate
away from the unit and mounting apparatus.
Mounting on ceiling
• Ensure that the ceiling is sturdy enough to support theweight of the unit and the mounting apparatus over time,
against earthquakes, unexpected vibrations, and other
external forces.
• Be sure the unit is mounted to a solid structure within the ceiling, such as a support beam. Secure the monitor
using bolts, spring lock washers, washer and nut.
• DO NOT mount to areas that have no supporting internal structure. DO NOT use wood screws or anchor screws
for mounting. DO NOT mount the unit to trim or to
hanging fixtures.
Maintenance
• Periodically check for loose screws, gaps, distortions, orother problems that may occur with the mounting
apparatus. If a problem is detected, please refer to
qualified personnel for service.
• Regularly check the mounting location for signs of damage or weakness that may occur over time.
Orientation
• When using the display in the portrait position, themonitor should be rotated clockwise so that the left side
is moved to the top and the LED indicator light is on the
bottom. This will allow for proper ventilation and will
extend the lifetime of the monitor. Improper ventilation
may shorten the lifetime of the monitor.
