FCC Safety Compliance Statement
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 antennas, Cisco
Catalyst 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.

• If any part of the antenna system comes in contact with a power line, do not touch it or remove it yourself.
If an accident should occur, call for qualified emergency help immediately.
Avoiding Damage to Radios in a Testing Environment
The radios on outdoor units (bridges) have higher transmit power levels than radios on indoor units (APs).
When you test high-power radios in a link, you must avoid exceeding the receiver's maximum receive input
level. At levels above the normal operating range, packet error rate (PER) performance is degraded. At even
higher levels, the receiver can be permanently damaged. To avoid receiver damage and PER degradation, you
can use one of the following techniques:
• Separate the omnidirectional antennas by at least 2 ft (0.6 m) to avoid receiver damage or by at least 25
