RF Exposure Warning
RF Exposure Warning
This transmitting equipment conforms to SAR (Specific Absorption Rate) limits regarding exposure of human
beings to radio frequency electromagnetic energy, as defined in the following national and international standards
and guidelines:
1. Industry Canada Radio Standards Specification 102 (RSS-102), Evaluation Procedure for Mobile and
Portable Radio Transmitters with respect to Health Canada’s Safety Code 6 for Exposure of Humans to
Radio Frequency Fields;
2. Health Canada Safety Code 6, Limits of Human Exposure to Radiofrequency Electromagnetic Fields in the
Frequency Range from 3 kHz to 300 GHz
1
;
3. United States Federal Communications Commission, Code of Federal Regulations; 47 CFR Part 1,
§ 1.1310 Radiofrequency radiation exposure limits; and
4. American National Standards Institute (ANSI) criteria for localized SAR in Section 4.2 of “IEEE Standard
for Safety Levels with Respect to Human Exposure to Radio Frequency Electromagnetic Fields, 3 kHz to
300 GHz”
2
.
Notes: A. The SAR limit for uncontrolled exposure of persons not classed as RF and microwave exposed
workers (including the general public) for transmitter equipment operating below 10 GHz, as defined
in the references above, is 2 W/m
2
(0.2 mW/cm
2
).
B. This transmitting equipment is designed for use with an outdoor antenna with a characteristic antenna
gain of 10 dBi, typically mounted at a significant height above ground to provide for adequate signal
coverage. To ensure that the general public is not exposed to a power density above the recommended
limit of 2 W/m
2
(0.2 mW/cm
2
), the equipment must be installed such that the following minimum safe
distances from the antenna are maintained:
6.3 m (20.7 ft) when configured with 100 W PA
3.5 m (11.3 ft) when configured with 30 W PA
1.8 m (5.9 ft) standalone (i.e. no PA) 8 W
C. The following power density formula has been utilized in determining minimum safe distances:

π
=
where: S = Power density (in appropriate units, e.g. mW/cm
2
)
P = Power input to the Antenna (in appropriate units, e.g., mW)
G = Power gain of the antenna in the direction of interest relative to an isotropic radiator
R = Distance to the center of radiation of the antenna (appropriate units, e.g., cm)
