The part number system for a stand-alone RF board/Heat Sink assembly is the same as that for a
module except that “F” designator (regulator option) does not exist and a “D” is appended at the
end.

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.

SAFETY STANDARDS-RF EXPOSURE (DTX-165/265, 365/465))
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
COMPLI
ANCE WITH THE FCC’S AND IC’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/IC
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, 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.
