MANDATORY SAFETY INSTRUCTIONS TO INSTALLERS AND USERS
• Use only manufacturer or dealer supplied antennas.
• Antenna Minimum Safe Distance: 40 cm (16 inches), 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. 40 cm (16 inches) , 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 40 cm (16 inches), 50% duty Cycle.
“This transmitter is authorized to operate with a maximum duty factor of 50%, in
typical push-to-talk mode, for satisfying FCC RF exposure compliance requirements.”
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,
