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 radio 
frequency (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 recom-
mended 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, manufac-
tured and tested to ensure they meet government established 
RF exposure levels. In addition, manufacturers also recom-
mend specific operating instructions to users of two-way 
radios. These instructions are important because they inform 
users about RF energy exposure and provide simple proce-
dures 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.

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. Expo-
sure 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. 

Your EFJohnson two-way radio is designed and tested 

to comply with a number of national and international stan-
dards and guidelines (listed below) regarding human expo-
sure 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: 

•

United States Federal Communications Commission, 
Code of Federal Regulations; 47 CFR §§ 2 sub-part J. 

•

American National Standards Institute (ANSI) / Institute 
of Electrical and Electronic Engineers (IEEE) C95. 1-
1992. 

•

Institute of Electrical and Electronic Engineers (IEEE) 
C95.1-1999 Edition. 

To control exposure to yourself and others and ensure 

compliance with the occupational/controlled environment 
exposure limits always adhere to the following procedures.
