FCC Safety Compliance Statement
FCC Compliance 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
publication results in user exposure substantially below the FCC recommended limits.

Safety Precautions
Each year hundreds of people are killed or injured when attempting to install an antenna. In many of
these cases, the victim was aware of the danger of electrocution but did not take adequate steps to avoid
the hazard.

Plan your installation carefully and completely before you begin. Successfully raising a mast or
tower is largely a matter of coordination. Each person should be assigned to a specific task and
should know what to do and when to do it. One person should be in charge of the operation to issue
instructions and watch for signs of trouble.

If the assembly starts to drop, get away from it and let it fall. Remember that the antenna, mast,
cable, and metal guy wires are all excellent conductors of electrical current. Even the slightest touch
of any of these parts to a power line completes an electrical path through the antenna and the
installer: you!
