5. 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.
NOTE: The sound quality of the internal speakers will
differ according to the acoustics of the room.
6. 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. For the X651UHD-2,
the clamps and screws are included with the optional table
top stand.
