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
(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.
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 LCD 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.
