1.3 FCC REGULATIONS
1.3.1 LICENSING
For those frequency bands governed by FCC rules, the FCC requires that the radio owner obtain a station
license for his radio before using the equipment to transmit, but does not require an operating license or
permit. The station licensee is responsible for proper operation and maintenance of his radio equipment,
and for ensuring that transmitter power, frequency and deviation are within the limits specified by the
station license. This includes checking the transmitter frequency and deviation periodically using
appropriate methods. Note also, that wideband operation (25/30 kHz channel bandwidth) may not be
permitted.
1.3.2 PRODUCT CERTIFICATION
The High Power DTX modules are certified by the FCC for operation in the United States and by Industry
Canada for operation in Canada on certain frequency bands and sub-bands for transmission of either voice
or data signals when aligned according to the alignment procedure for the proper bandwidth and when
operated as a complete unit in the metal case. Operation of the RF board as a stand-alone unit or in
combination with any other equipment, in any mode outside the alignment procedure, or with the clipper
filter electronically disabled will require the filing of a new type acceptance application with the FCC by
the user.
1.3.3 SAFETY STANDARDS-RF EXPOSURE (DTX-165)
RF ENERGY EXPOSURE AWARENESS AND CONTROL INFORMATION, AND OPERATIONAL
INSTRUCTIONS FOR FCC OCCUPATIONAL USE REQUIREMENTS:
BEFORE USING THIS 2-WAY RADIO, READ THIS IMPORTANT RF ENERGY AWARENESS AND
CONTROL INFORMATION AND OPERATIONAL INSTRUCTIONS TO ENSURE COMPLIANCE
WITH THE FCC’S AND IC’S RF EXPOSURE GUIDELINES.
NOTICE: This radio is intended for use in general population/uncontrolled conditions.
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.
