• Use only manufacturer or dealer supplied antenna. 
• Antenna Minimum Safe Distance: 60 cm (2 feet), 50% duty Cycle. 
• Antenna Gain: 0 dBd referenced to a dipole. 
 
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. 
60 cm (2 feet) , 50% duty Cycle. 

• 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. 

• Vehicle installation: The antenna can be mounted at the center of a vehicle metal roof 

or trunk lid, if the minimum safe distance is observed. 

• Base  Station Installation: The antenna should be  fixed-mounted  on an outdoor 

permanent structure. RF Exposure compliance must be addressed at the time of 
installation. 

 
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. 
 

 

 

 

Maintain a separation distance from the antenna to person(s) of at least 
60 cm (2 feet) , 50% duty Cycle. 

 

 
 
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. Transmit 
only when people outside the vehicle are at least the recommended minimum lateral 
distance away from the antenna/vehicle
