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 2014/53/EU. Please
