This two-way radio uses electromagnetic energy in the radio frequency (RF) spectrum to provide
communications between two or more users over a distance. It uses RF energy or radio waves to send and
receive calls. RF energy is one form of electromagnetic energy. Other forms include, but are not limited
to, electric power, sunlight, and x-rays. RF energy, however, should not be confused with these other
forms of electromagnetic energy, which, when used improperly, can cause biological damage. Very high
levels of x-rays, for example, can damage tissues and genetic material.
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,
this 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.
