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. Please refer to the following web sites for
more information on what RF energy exposure is and how to control your exposure to assure
compliance with established RF exposure limits.

1.12.1 FEDERAL COMMUNICATIONS COMMISSION REGULATIONS
The FCC rules require manufacturers to comply with the FCC RF energy exposure limits for
mobile two-way radios before they can be marketed in the U.S. 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. Your EFJohnson two-way
radio has a RF exposure product label. Also, your EFJohnson user manual, or product manual, or
separate safety booklet includes information and operating instructions required to control your
RF exposure and to satisfy compliance requirements.
1.12.2 COMPLIANCE WITH RF EXPOSURE STANDARDS
Your EFJohnson two-way radio is designed and tested to comply with a number of national
and international standards and guidelines (listed below) regarding human exposure to radio
frequency electromagnetic energy. This radio complies with the IEEE and ICNIRP exposure
limits for occupational/controlled RF exposure environment at duty factors of up to 50% talk and
100% listen and is authorized by the FCC for occupational use. In terms of measuring RF energy
for compliance with the FCC exposure guidelines, your radio antenna radiates measurable RF
energy only while it is transmitting (during talking), not when it is receiving (listening) or in
standby mode.
Your EFJohnson two-way radio complies with the following RF energy exposure standards
and guidelines:
