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 occupational/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
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 electric power, radar, 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. The energy levels associated with radio waves from
portable 2-way radios, when properly used, are not great enough to cause biological damage.
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 2-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
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 exposure to assure
compliance with established RF exposure 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 occupational requirements. Exposure awareness can be
facilitated by the use of a product label directing users to specific user awareness information.
Your 2-way radio has a RF exposure product label. Also, the owner’s and service manuals
include information and operating instructions required to control your RF exposure and to
satisfy compliance requirements.
COMPLIANCE WITH RF EXPOSURE STANDARDS
Your 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 exposure limits for
occupational/controlled RF exposure environment at operating duty factors of up to 50%
transmitting and is authorized by the FCC for occupational 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.
Your 2-way radio complies with the following RF energy exposure standards and guidelines:
• United
States Federal Communications Commission, Code of
Federal Regulations; 47 CFR §§ 1.1307, 1.1310, 2.1091 and 2.1093
• 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
