Safety Information
The FCC, with its action in ET Docket 96-8, has adopted a safety standard for
human exposure to RF electromagnetic energy emitted by FCC-certified
equipment. When used with approved Cisco Aironet antennas, Cisco Aironet
products meet the uncontrolled environmental limits found in OET-65 and
ANSI C95.1, 1991. Proper operation of this radio device according to the
instructions in this document and the installation and configuration guide will
result in user exposure substantially below the FCC recommended limits.
•Do not hold any component containing a radio such that the antenna is
very close to or touching any exposed parts of the body, especially the
face or eyes, while transmitting.
•The use of wireless devices in hazardous locations is limited to the
constraints posed by the safety directors of such environments.
