Experts in science, engineering, medicine, health, and industry work with organizations to develop
standards for exposure to RF energy. These standards provide recommended levels of RF exposure for 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:

1.3 FEDERAL COMMUNICATIONS COMMISSION REGULATIONS
Before it was marketed in the United States, the XL 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 using a label directing users to
specific user awareness information. The radio has an RF exposure product label. Also, the Product Safety
Manual and the applicable Operator’s Manual include information and operating instructions required to
control RF exposure and to satisfy compliance requirements.
1.4 COMPLIANCE WITH RF EXPOSURE STANDARDS
The XL Mobile two-way mobile radio is designed and tested to comply with multiple 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.
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.
