RF EXPOSURE INFORMATION
RF ENERGY EXPOSURE AWARENESS AND CONTROL 
INFORMATION, AND OPERATIONAL INSTRUCTIONS 
FOR FCC OCCUPATIONAL USE REQUIREMENTS
BEFORE USING YOUR PORTABLE 2-WAY 
RADIO, READ THIS IMPORTANT RF ENERGY 
AWARENESS AND CONTROL INFORMATION 
AND OPERATIONAL INSTRUCTIONS TO 
ENSURE COMPLIANCE WITH THE FCC’S RF 
EXPOSURE GUIDELINES.
NOTICE: This radio is intended for use in occupa-
tional/controlled conditions, where users have full 
knowledge of their exposure and can exercise control 
over their exposure to meet FCC limits. This radio 
device is NOT authorized for general population, 
consumer, or any other use.
This 2-way radio uses electromagnetic energy in 
the radio frequency (RF) spectrum to provide commu-
nications 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 elec-
tromagnetic 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 stan-
dards 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 2-way radios marketed in North 
America are designed, manufactured and tested to 
ensure they meet government established RF expo-
sure levels. In addition, manufacturers also recom-
mend specific operating instructions to users of 2-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 websites for more information on what 
RF energy exposure is and how to control your expo-
sure to assure compliance with established RF expo-
sure limits.

FEDERAL COMMUNICATIONS COMMISSION 
REGULATIONS
The FCC rules require manufacturers to comply 
with the FCC RF energy exposure limits for portable 
2-way radios before they can be marketed in the U.S. 
When 2-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 occupa-
tional requirements. Exposure awareness can be facili-
tated by the use of a product label directing users to 
specific user awareness information. Your EFJohnson 
2-way radio has a RF exposure product label. Also, 
your EFJohnson user manual, or product manual, or 
separate safety booklet includes information and oper-
ating instructions required to control your RF exposure 
and to satisfy compliance requirements. 
COMPLIANCE WITH RF EXPOSURE 
STANDARDS
Your EFJohnson 2-way radio is designed and tested to 
comply with a number of national and international 
standards and guidelines (listed below) for human 
exposure to radio frequency electromagnetic energy. 
This radio complies with the IEEE and ICNIRP expo-
sure limits for occupational/controlled RF exposure 
environment at operating duty factors of up to 50% 
transmitting and is authorized by the FCC for occupa-
tional use only. In terms of measuring RF energy for 
compliance with the FCC exposure guidelines, your 
radio radiates measurable RF energy only while it is 
transmitting (during talking), not when it is receiving 
(listening) or in standby mode. Note: The approved 
batteries supplied with this radio are rated for a 5-5-90 
duty factor (5% talk-5% listen - 90% standby), even 
though this radio complies with the FCC occupational 
RF exposure limits and may operate at duty factors of 
up to 50% talk.
