ES820 Hardware Guide: Installation
4
WARNING:
If the
Mesh Point con-
nects to outside-mount-
ed antennas, failure to
provide a low resistive
earth ground can result
in migration of voltage
from lightning or line
surges onto the premis-
es wiring, which can
cause electric shock
and/or fire within the
building or structure.
Grounding:
Ground the ES820 by mounting it with direct
contact to the vehicle chassis.
Radio Frequency:
The Mesh Point’s internal radios conform
to the FCC’s safety standard for human exposure to RF
electromagnetic energy, provided that you follow these
guidelines:
Do not touch or move the antennas while the unit is
transmitting or receiving.
To safeguard Mesh Point transmitting circuitry, relocate
the Mesh Point and its antennas only when the Mesh
Point is powered off.
When the Mesh Point is transmitting, do not hold it so
that the antenna is very close to or touching any
exposed parts of the body, especially the face or eyes.
Antennas must be installed to provide a separation of at
least 20 cm (7.9") from all persons and any co-located
antenna or transmitter.
Regarding use in specific environments: · Do not
operate near unshielded blasting caps or in an
explosive environment. · Limit use in a hazardous
location to the constraints imposed by the location’s
safety director. · Abide by the rules of the Federal
Aviation Administration for the use of wireless devices
on airplanes. · Restrict the use of wireless devices in
hospitals to the limits set forth by each hospital.
