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 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 Qualifi 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 recommends mounting interfaces that comply with 
UL1678 standard in North America.
• 
V552: 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) Bracket hole 
should be under φ 8.5 mm.
• 
V652: NEC strongly recommends using size M8 screws 
(15-17 mm + thickness of bracket in length). If using 
screws longer than 15-17 mm, check the depth of the 
hole. (Recommended Fasten Force: 1125 - 1375N•cm) 
Bracket hole should be under φ10.0 mm.
• 
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.
