Understanding safety alert messages

Observe these precautions to avoid exposure to RF radiation, a potential safety
hazard:
The antenna must be installed in a location not readily accessible to children and
in a manner that prevents human exposure to potentially harmful levels of
radiation.
Antennas mounted in Puerto Rico, the continental United States, or at any site
with a greater than 30° elevation angle must be installed such that the lower lip
of the antenna reflector is at least 5 ft above any surface upon which a person
might be expected to stand, and 3 ft 3 inches from any opening (such as a door
or window) in a building or adjacent structure.
Antennas mounted in Canada, Alaska, Hawaii, or any site with a less than 30°
elevation must be installed such that the lower lip of the antenna reflector is at
least 5 ft 9 inches above any surface upon which a person might be expected to
stand, and 3 ft 3 inches from any opening (such as a door or window) in a
building or adjacent structure.
The antenna must be mounted such that no object that could reasonably be
expected to support a person is within 6 ft 7 inches of the edges of a cylindrical
space projecting outward from the antenna reflector toward the satellite.
If the above distance requirements cannot be met, the antenna must be
mounted in a controlled area inaccessible to the general public, such as a fenced
enclosure or a roof.
A fenced installation must have a locked entry, and the fenced area must be
large enough to protect the general public from exposure to potentially harmful
levels of radiation.
Access to a roof installation in a commercial, industrial, or institutional
environment must be limited by a door or a permanently fastened ladder that is
locked to deny access to the general public.
Once the transmitter becomes operational, maintain a safe distance; at least 3
feet.
Failure to observe these cautions could result in injury to eyes or other personal
injury.
