RF Radiation Information
RF Radiation Profile
Radio Frequency (RF) is a frequency of electromagnetic radiation in the range at which radio
signals are transmitted. RF technology is widely used in communication, medicine, food
processing and other fields. It may generate radiation during use.
RF Radiation Safety
In order to ensure user health, experts from relevant industries including science, engineering,
medicine and health work with international organizations to develop standards for safe
exposure to RF radiation. These standards consist of:
United States Federal Communications Commission, Code of Federal Regulations; 47CFR part 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;
International Commission on Non-Ionizing Radiation Protection (ICNIRP) 1998;
FCC Regulations
Federal Communication Commission (FCC) requires that all radio communication products should
meet the requirements set forth in the above standards before they can be marketed in the U.S,
and the manufacturer shall post a RF label on the product to inform users of operational
instructions, so as to enhance their occupational health against exposure to RF energy.
Operational Instructions and Training Guidelines
To ensure optimal performance and compliance with the Population/Uncontrolled Exposure environment
RF energy exposure limits in the above standards and guidelines, users should transmit no more
than 50% of the time and always adhere to the following procedures:
a. Your radio radiates measurable RF energy only while it is transmitting (during talking), not
when it is receiving (listening) or in standby mode.
b. Keep the radio at least 2.5 centimeters away from your body during transmission.
