RF Radiation Information
RF Radiation Profile
Your 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 occupational/controlled RF exposure environment at operating duty factors of up to 50% transmitting. 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 in PTT mode), not when it is receiving (listening) or in standby mode.
The device complies with SAR and/or RF field strength limits of RSS-102 requirement
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 SHAIL 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.
Part 15 Compliance
This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules.
These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment
generates uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause
harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular
installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning
the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:
● Reorient or relocate the receiving antenna.
● Increase the separation between the equipment and receiver.
● Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
● Consult the dealer or an experienced radio/TV technician for help. Note: “Changes or modifications to this unit not expressly
approved by the party responsible for compliance could void the user’s authority to operate the equipment.”
EU Regulatory Conformance
As certified by the qualified laboratory, the product is in compliance with the essential requirements and other relevant
provisions of the Directive 1999/5/EC. Please note that the above information is applicable to EU countries only.
