IMPORTANT SAFETY INSTRUCTIONS

This warning symbol means danger. You are in a situation that could cause bodily injury. Before you
work on any equipment, be aware of the hazards involved with electrical circuitry and be familiar
with standard practices for preventing accidents. Use the statement number provided at the end of
each warning to locate its translation in the translated safety warnings that accompanied this
device.

SAVE THESE INSTRUCTIONS

In order to comply with FCC radio frequency (RF) exposure limits, antennas should be located at a
minimum of 7.9 inches (20 cm) or more from the body of all persons.

Statement 1071

Statement 332

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.

For your safety, and to help you achieve a good installation, please read and follow these safety
precautions. They may save your life!

1. If you are installing an antenna for the first time, for your own safety as well as others, seek

professional assistance. Your Cisco sales representative can explain which mounting method to use
for the size and type antenna you are about to install.

2. Select your installation site with safety, as well as performance in mind. Remember: electric power

lines and phone lines look alike. For your safety, assume that any overhead line can kill you.

3. Call your electric power company. Tell them your plans and ask them to come look at your proposed

installation. This is a small inconvenience considering your life is at stake.

4. Plan your installation carefully and completely before you begin. Successful raising of 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.

5. When installing your antenna, remember:

a. Do not use a metal ladder.

b. Do not work on a wet or windy day.

c. Do dress properly—shoes with rubber soles and heels, rubber gloves, long sleeved shirt or

jacket.

6. If the assembly starts to drop, get away from it and let it fall. Remember, 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 complete an electrical path through the antenna and the installer: you!
