Installation

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.
For further mounting information see page 6.
For stand installation see page 8~9.

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. Not all walls or ceilings are capable
of supporting the weight of the unit. Product
warranty does not cover damage caused by improper
installation, remodeling, 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 (10mm + thickness
of bracket in length). If using
screws longer than 10mm, 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.

Mounting location

The ceiling and wall must be strong enough to support the
monitor and mounting accessories.

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 (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 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 fixtures.
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
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, 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 ex-
tend the lifetime of the monitor. Improper ventilation may
shorten the lifetime of the monitor.
