For contents, please refer to the contents sheet.
This 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 your
supplier. 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, re-
modeling, 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 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
NEC recommends mounting interfaces that comply with
UL1678 standard in North America.
NEC strongly recommends
using size M6 screws
(8-10 mm + thickness
of bracket and washers in
length). If using screws
longer than 8-10 mm,
check the depth of the hole.
(Recommended Fasten
Force: 470 - 635 N•cm). Bracket
hole should be under ϕ 8.0 mm.
Prior to mounting, inspect the installation location to
ensure that it is strong enough to support the weight of
the unit so that the unit will be safe from harm.
For detailed information, refer to the instructions included
with the mounting equipment.
Make sure that there is no gap between the monitor and
the bracket.
When used in a video wall configuration for a longer
time, slight expansion of the monitors may happen due to
temperature changes. Due to this it is recommended that
over one millimeter gap is kept between adjacent monitor
edges.
When installing, do not apply pressure to the screen or
excessive force to any part of the monitor by pushing
or leaning on it. This may cause the monitor to become
distorted or damaged.

To prevent the LCD monitor from falling off from the wall or
ceiling, NEC strongly recommends using a safety wire.
Please install LCD monitor in a spot of the wall or ceiling
strong enough to support the monitor.
Prepare the LCD monitor using mounting accessories such
as hook, eyebolt or mounting parts and then secure the LCD
monitor with a wire. The safety wire must not be tight.
CAUTION: Do not attempt to hang the monitor using an
installation safety wire. The monitor must be
properly installed.
Please make sure the mounting accessories are strong
enough to support the LCD monitor before mounting it.
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 the monitor next to a location where the
main power supply is fed into the building.
DO NOT install the monitor in a location where people
can easily grab and hang onto the unit or the mounting
equipment.
Allow for adequate ventilation or provide air conditioning
around the monitor, so that heat can properly dissipate
away from the monitor and from the mounting equipment.
Mounting on ceilings
Ensure that the ceiling is sturdy enough to support the
weight of the unit and the mounting equipment 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 ceiling or to hanging
fixtures.
Maintenance
Periodically check for loose screws, gaps, distortions,
or other problems that may occur with the mounting
equipment. 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.
