MANDATORY SAFETY INSTRUCTIONS TO INSTALLERS AND USERS
• 
Use only manufacturer or dealer supplied antenna.
• 
Antenna Minimum Safe Distance:  180 cm (6 feet), 50% duty Cycle.
• 
Antenna Gain:  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. 180 cm (6 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 fi xed-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 
180 cm (6 feet) 50% duty Cycle.
You, as the qualifi ed 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.
