The Federal Communications Commission has adopted a safety standard for human exposure to RF (Radio 
Frequency) energy which is below the OSHA (Occupational Safety and Health Act) limits. 

 
Antenna Mounting:  The antenna supplied by the manufacturer or radio dealer must not be mounted at a 

location such that during radio transmission, any person or persons can come closer than the above 
indicated minimum safe distance to the antenna i.e. 70cm. 

 
To comply with current FCC RF Exposure limits, the antenna must be installed at or exceeding the 

minimum safe distance shown above, and in accordance with the requirements of the antenna 
manufacturer or supplier. 

 
Antenna Substitution:  Do not substitute any antenna for the one supplied or recommended by the 
manufacturer or radio dealer.  You may be exposing person or persons to excess radio frequency radiation.  

You may contact your radio dealer or the manufacturer for further instructions. 
 

Warning: Maintain a separation distance from the antenna to a person(s) of at least 70cm. 
 

You, as the qualified end-user of this radio device must control the exposure conditions of bystanders to 
ensure the minimum separation distance (above) is maintained between the antenna and nearby persons 

for satisfying RF Exposure compliance.  The operation of this transmitter must satisfy the requirements of 
Occupational/Controlled Exposure Environment, for work-related use.  Transmit only when person(s) are at 

least the minimum distance from the properly installed, externally mounted antenna.
