MANDATORY SAFETY INSTRUCTIONS TO INSTALLERS AND USERS
• 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
