Your 

KIRISUN

 radio generates RF electromagnetic energy during 

transmit mode. This radio is designed for and classified as “Occupational Use Only”, meaning it must be 
used only during the course of employment by individuals aware of the hazards, and the ways to minimize 
such hazards. This radio is NOT intended for use by the “General Population” in an uncontrolled 
environment. 
This radio has been tested and complies with the FCC RF exposure limits for “Occupational Use Only”. In 
addition, your 

KIRISUN

 radio complies with the following Standards and Guidelines with regard to RF 

energy and electromagnetic energy levels and evaluation of such levels for exposure to humans: 
 FCC OET Bulletin 65 Edition 97-01 Supplement C, Evaluating Compliance with FCC Guidelines for 
Human Exposure to Radio Frequency Electromagnetic Fields.     
American National Standards Institute (C95.1-1992), IEEE Standard for Safety Levels with Respect to 
Human Exposure to Radio Frequency Electromagnetic Fields, 3 kHz to 300 GHz.  American National 
Standards Institute (C95.3-1992), IEEE Recommended Practice for the Measurement of Potentially 
Hazardous Electromagnetic Fields– RF and Microwave.     
The following accessories are authorized for use with this product. Use of accessories other than those (listed 
in the instruction) specified may result in RF exposure levels exceeding the FCC requirements for wireless 
RF exposure. 

To ensure that your expose to RF electromagnetic energy is within the 

FCC allowable limits for occupational use, always adhere to the following guidelines 

DO NOT

 operate the radio without a proper antenna attached, as this may damaged the radio and may also 

cause you to exceed FCC RF exposure limits. A proper antenna is the antenna supplied with this radio by the 
manufacturer or antenna specifically authorized by the manufacturer for use with this radio. 

DO NOT

 transmits for more than 50% of total radio use time (“50%duty cycle”). Transmitting more than 

50% of the time can cause FCC RF exposure compliance requirements to be exceeded. The radio is
