MANDATORY SAFETY INSTRUCTIONS
FOR INSTALLERS AND USERS
Use only manufacturer or dealer supplied antennas.
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.
The term “IC:” before the certification/registration number only signifies that the Industry Canada technical
specifications were met.
Base Station Antenna minimum safe distance: 7.9 inches (20 cm) at 100% duty cycle.
Base Station Antenna gain: This device has been designed to operate with an antenna having a maximum
gain of up to 2dBi.
Antenna mounting: The antenna(s) used for the base transmitter must be installed to provide a separation
distance of at least 7.9 inches (20 cm) from all persons and must not be co-located or operating in conjunction
with any other antenna or transmitter.
Antenna substitution: Do not substitute any antenna for the one supplied 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 Base Station transmit antenna to a person(s) of at least
7.9 inches (20 cm) at 100% 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.
