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.

3. 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.
4. 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.

Before attaching the LCD monitor to the wall, make sure
that the wall can support the weight of the monitor.
