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 the monitor next to a location where the
main power supply is fed into the building.
• DO NOT install the monitor in a location where people
can easily grab and hang onto the unit or the mounting
equipment.
• Allow for adequate ventilation or provide air conditioning
around the monitor, so that heat can properly dissipate
away from the monitor and from the mounting equipment.
Mounting on ceilings
• Ensure that the ceiling is sturdy enough to support the
weight of the unit and the mounting equipment 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 ceiling or to hanging
fi xtures.
Maintenance
• Periodically check for loose screws, gaps, distortions,
or other problems that may occur with the mounting
equipment. 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.
Orientation
• When using the monitor in the portrait position, it should
be rotated clockwise so that the left side is moved to
the top, right side is moved to 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.
• When using the monitor in the portrait position, the NEC
logo ornament position can be changed.
