Mounting location
CAUTION
• The ceiling or 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.
NOTE: 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 fixtures.
