CAUTION
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 and is authorised 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 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 requirements. 
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.
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
