
The density of the materials used in a building's construction determines the number of walls the signal must pass through
and still maintain adequate coverage. Consider the following before choosing the location to install your antenna:
— Paper and vinyl walls have very little effect on signal penetration.
— Solid and precast concrete walls limit signal penetration to one or two walls without degrading coverage.
— Concrete and wood block walls limit signal penetration to three or four walls.
— A signal can penetrate five or six walls constructed of drywall or wood.
— A thick metal wall or wire-mesh stucco walls causes signals to reflect back and cause poor penetration.

Avoid mounting the antenna next to a column or vertical support that could create a shadow zone and reduce the coverage
area.

Keep the antenna away from reflective metal objects such as heating and air-conditioning ducts, large ceiling trusses,
building superstructures, and major power cabling runs. If necessary, use an extension cable to relocate the antenna away
from these obstructions.
CAUTION: Install the EHWIC and any antennas away from appliances that share the same frequency bands. Microwave ovens,
cordless telephones, and security monitors can temporarily interfere with wireless performance.
CAUTION: We recommend you avoid installing wireless antennas in or near rack-mounted installations that include networking
equipment and computer servers whose radiated noise emissions can severely degrade radio performance.

Safety Instructions

Follow these safety instructions when installing your antenna:

Plan your installation procedure carefully and completely before you begin.

If you are installing an antenna for the first time, for your own safety as well as that of others, seek professional assistance.
Consult your dealer, who can explain which mounting method to use for the location where you intend to install the antenna.

Choose your installation site with safety as well as performance in mind. Remember that electric power cables and
telephone lines look alike. For your safety, assume that any line is an electric power line until determined otherwise.

Call your local power company or building maintenance organization if you are unsure about cables close to your mounting
location.

When installing your antenna, do not use a metal ladder. Do dress properly: shoes with rubber soles and heels, rubber
gloves, and a long-sleeved shirt or jacket.

If an accident or emergency occurs with the power lines, call for qualified emergency help immediately.
WARNING: 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 332
CAUTION: Do not work on the system or connect or disconnect cables during periods of lightning activity. Statement 1001
CAUTION: This equipment must be grounded. Never defeat the ground conductor or operate the equipment in the absence of
a suitably installed ground conductor. Contact the appropriate electrical inspection authority or an electrician if you are uncertain
that suitable grounding is available. Statement 1024
CAUTION: Only trained and qualified personnel should be allowed to install, replace, or service this equipment. Statement 1030
