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-165-RR-SIG two-way radio has an RF exposure product label. Also, this DTX-165-RR-
SIG manual includes information and operating instructions required to control your RF exposure
and to satisfy compliance requirements.
Compliance with RF Exposure Standards:
The DTX-165-RR-SIG 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 general population/uncontrolled 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:
Guidelines:
• User awareness instructions should accompany device when transferred to other users.
• Do not use this device if the operational requirements described herein are not met.
