•  Position the monitor at a 90° angle to windows and other light  sources to minimize glare and refl ections.
•  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 fi xed 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 benefi ts, 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 diffi cult to see and may produce eye fatigue due to 
insuffi cient contrast.
Cleaning the LCD Panel
•  When the liquid crystal panel is dusty, please gently wipe with a soft 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.

•  To clean the cabinet, dampen the cloth with a neutral detergent and water, wipe the cabinet and follow with a dry 
cloth.
NOTE:   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 fl uids and materials can 
cause the paint to deteriorate, crack or peel.

EnglishThis device cannot be used or installed without the Tabletop 
Stand or other mounting accessory for support. For proper 
installation it is strongly recommended to use a trained, 
NEC authorized service person. Failure to follow NEC 
standard mounting procedures could result in damage to the 
equipment or injury to the user or installer. Product warranty 
does not cover damage caused by improper installation. 
Failure to follow these recommendations could result in 
voiding the warranty.
Mounting
DO NOT mount the monitor yourself. Please ask dealer. 
For proper installation it is strongly recommended to use 
a trained, qualifi ed 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 Quali ed Personnel:
To ensure 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 
(10-12 mm + thickness 
of bracket and washers in 
length). If using screws 
longer than 10-12 mm, 
check the depth of the hole. 
(Recommended Fasten 
Force: 470 - 635N•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. 
•  Make sure there is no gap between the monitor and the  bracket. 
Installation
Orientation 
•  When using the display in the portrait position, the monitor 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.
LED Indicator
Mounting location 
•  The ceiling and wall must be strong enough to support the 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 in 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 (100 mm) 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 the weight 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 
fi xtures.
Maintenance 
•  Periodically check for loose screws, gaps, distortions, or other problems that may occur with the mounting 
apparatus. If a problem is detected, please refer to 
qualifi ed personnel for service.
•  Regularly check the mounting location for signs of  damage or weakness that may occur over time.

Attaching Mounting Accessories
The monitor is designed for use with the VESA mounting 
system.
1. Attach Mounting Accessories
Be careful to avoid tipping monitor when attaching 
accessories.
VESA Mounting Interface
300 mm
300 mm
Mounting accessories can be attached with the monitor in 
the face down position. To avoid damaging the screen face, 
place the protective sheet on the table underneath the LCD. 
The protective sheet was wrapped around the LCD in the 
original packaging. Make sure there is nothing on the table 
that can damage the monitor.
When using mounting accessories other than NEC compliant 
and approved, they must comply with the VESA-compatible 
mounting method.
2. Using Option Board
1. Turn off the main power switch.
2. Remove the attached slot cover by unscrewing the installed screws ( Figure 1).
3. Insert option board in to the monitor.
NOTE:   Please contact your supplier for available option 
boards.
Do not apply excessive force to manipulate the 
optional board before fi xing it with screws.
Figure 1
3. Installing and removing optional table top stand
CAUTION:   Installing and removing the stand must be done 
by two or more people.
To install, follow those instructions included with the stand or 
mounting apparatus. Use only those devices recommended 
by the manufacturer.
NOTE:  Use ONLY thumbscrews which are included with 
the optional table top stand.
When installing the LCD monitor stand, handle the unit with 
care to avoid pinching your fi ngers.
Optional table top stand
Table Protective Sheet
NOTE:  Install the stand so the long end of the feet face 
forward. Use the ST-322.
4. Ventilation  Requirements 
When mounting in an enclosed space or recessed area, 
leave adequate room between the monitor and the enclosure 
to allow heat to disperse, as shown below.
Allow adequate ventilation or provide air conditioning around 
the monitor, so that heat can properly dissipate away from 
the unit and mounting apparatus; especially when you use 
monitors in multiple screen.
NOTE:  The sound quality of the internal speakers will 
differ according to the acoustics of the room.

5. Prevent Tipping
When using the display with the optional table top stand 
fasten the LCD to a wall using a cord or chain that can 
support the weight of the monitor in order to prevent the 
monitor from falling. Fasten the cord or chain to the monitor 
using the provided clamps and screws.
