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, 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.
http://www.fcc.gov/oet/rfsafety/rf-faqs.html
http://www.osha.gov/SLTC/radiofrequencyradiation/index.html
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

4
a product label directing users to specific user awareness information. Hytera’s 2-way radio has a
RF exposure product label. Also, Hytera’s user manual, or product manual, or separate safety
booklet includes information and operating instructions required to control your RF exposure and
to satisfy compliance requirements.
This device complies with part 15 of the FCC Rules. Operation is subject to the following two
conditions: (1) This device may not cause harmful interference, and (2) this device must accept
any interference received, including interference that may cause undesired operation.
Any Changes or modifications not expressly approved by the party responsible for compliance
could void the user's authority to operate the equipment.
Compliance with RF Exposure Standards
Hytera’s 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.
Hytera’s 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
RF Exposure Compliance and Control Guidelines and Operating Instructions
To control your exposure and ensure compliance with the occupational/controlled environment
exposure limits always adhere to the following procedures.
Guidelines:
•Do not remove the RF Exposure Label from the device.
• 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.

5
Operating Instructions:
•Transmit no more than the rated duty factor of 50 % of the time. To transmit (talk), push the
Push-To-Talk (PTT) button. To receive calls, release the PTT button. Transmitting 50 % of the
time, or less, is important because this radio generates measurable RF energy exposure only when
transmitting (in terms of measuring for standards compliance).
• Hold the radio in a vertical position in front of face with the microphone (and the other parts of
the radio, including the antenna) at least one inch (2.5 cm) away from the nose. Keeping the
radio at the proper distance is important because RF exposures decrease with distance from the
antenna. Antenna should be kept away from eyes.
• When worn on the body, always place the radio in a Hytera’s approved clip, holder, holster, case,
or body harness for this product. Using approved body-worn accessories is important because the
use of Hytera’s or other manufacturer’s non-approved accessories may result in exposure levels,
which exceed the FCC’s occupational/controlled environment RF exposure limits.
•If you are not using a body-worn accessory and are not using the radio in the intended use
position in front of the face, then ensure the antenna and the radio are kept at least 2.5 cm (one
inch) from the body when transmitting. Keeping the radio at the proper distance is important
because RF exposures decrease with increasing distance from the antenna.
• Use only manufacturer’s name approved supplied or replacement antennas, batteries, and
accessories. Use of non-manufacturer-name approved antennas, batteries, and accessories may
exceed the FCC RF exposure guidelines.
• For a list of Hytera’s approved accessories (see the user manual), or (visit the following website
