both workers and the general public. These recommended RF exposure levels include substantial margins
of protection. All two-way radios marketed in North America are designed, manufactured, and tested to
ensure they meet government-established RF exposure levels. In addition, manufacturers also recommend
specific operating instructions to users of two-way radios. These instructions are important because they
inform users about RF energy exposure and provide simple procedures on how to control it. Refer to the
following websites for more information on what RF energy exposure is and how to control exposure to
assure compliance with established RF exposure limits:

1.2.1 Federal Communications Commission Regulations
Before it was marketed in the United States, the Unity XG-100M two-way mobile radio was tested to
ensure compliance with FCC RF energy exposure limits for two-way mobile radios. When two-way
radios are used as a consequence of employment, the FCC requires users to be fully aware of and able to
control their exposure to meet occupational requirements. Exposure awareness can be facilitated by the
use of a label directing users to specific user awareness information. The radio has an RF exposure
product label. Also, this Installation and Product Safety Manual and the applicable Operator’s Manual
include information and operating instructions required to control RF exposure and to satisfy compliance
requirements.
1.3 COMPLIANCE WITH RF EXPOSURE STANDARDS
The Unity XG-100M two-way mobile radio is designed and tested to comply with a number of national
and international standards and guidelines regarding human exposure to RF electromagnetic energy. This
radio complies with the IEEE and ICNIRP exposure limits for occupational/controlled RF exposure
environment at duty-cycle times of up to 50% (50% transmit, 50% receive), and it is authorized by the
FCC for occupational use. In terms of measuring RF energy for compliance with the FCC exposure
guidelines, the radio’s antenna radiates measurable RF energy only while it is transmitting (talking), not
when it is receiving (listening), or in a standby mode.
The Unity XG-100M two-way mobile radio complies with the following RF energy exposure standards
and guidelines:
• United States Federal Communications Commission (FCC), Code of Federal Regulations; 47 CFR
§ 2 sub-part J.
• American National Standards Institute (ANSI)/Institute of Electrical and Electronic Engineers (IEEE)
C95.1-2005.
• Institute of Electrical and Electronic Engineers (IEEE) C95.1-2005.
• IC Standard RSS-102, Issue 2, 2005: Spectrum Management and Telecommunications Radio
Standards Specification. Radiofrequency Exposure Compliance of Radiocommunication Apparatus
(All Frequency Bands).
Table 1-1 lists the recommended minimum safe lateral distances
for a controlled
environment and for unaware bystanders in an uncontrolled environment, from
transmitting antennas (i.e., monopoles over a ground plane, or dipoles) at rated radio
power for mobile radios installed in a vehicle. Transmit only when unaware bystanders
are at least the uncontrolled recommended minimum safe lateral distance away from
the transmitting antenna.
Based on the highest radiated RF power and the highest antenna gain in antennas to be used with Unity
XG-100M, the distances listed in Table 1-1 are considered as safe distances for controlled and
