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, 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 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 mobile 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 label directing users to
specific user awareness information.
The DTX 2-way radio has an RF exposure product label. Also, this DTX manual includes information and
operating instructions required to control your RF exposure and to satisfy compliance requirements.
Compliance with RF Exposure Standards:
The DTX 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 50% 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. The DTX 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:
