6 RF ENERGY EXPOSURE
6.1 RF ENERGY EXPOSURE AWARENESS, CONTROL INFORMATION, AND
OPERATIONAL INSTRUCTIONS FOR COMPLIANCE WITH FCC RF EXPOSURE
LIMITS
NOTE: This power amplifier product is intended for use in environments in which personnel
have full knowledge of their exposure and can exercise control over their exposure to
meet FCC limits. This power amplifier is NOT authorized for use by the general
population, consumer, or for use under conditions where unintended or accidental
exposure may occur.
This power amplifier product generates electromagnetic energy in the radio frequency (RF)
spectrum to provide communications between users over a distance. RF energy is one specific
form of electromagnetic energy. Other forms include, but are not limited to, sunlight and x-rays. RF
energy, however, should not be confused with these other forms of electromagnetic energy, which
when used improperly, can cause biological damage. Very high levels of x-rays, for example, can
damage tissues and genetic material.
Experts in science, engineering, medicine, health, and industry work with organizations to develop
standards for safe exposure to RF energy. These standards provide recommended acceptable
levels for personnel who may be exposed to RF energy. The RF exposure levels described therein
include substantial margins of protection.
When properly installed and used, Crescend power amplifier products meet all government-
established RF exposure levels. In addition, Crescend recommends specific operating instructions
for users of its power amplifier products. These instructions are important because they inform
users about RF energy exposure and provide simple procedures on how to control it.
Please refer to the following Web sites for more information on the nature of RF energy exposure
and how to control your exposure to assure compliance with established RF exposure limits.

6.2 FEDERAL COMMUNICATION COMMISSION REGULATIONS
The FCC rules require manufacturers to comply with the FCC RF energy exposure limits for
communication devices before they can be marketed in the U.S. The FCC further requires users to
be fully aware of and able to control their exposure to meet RF energy exposure limits. This
document includes operating instructions and information required to control your RF exposure and
to satisfy compliance requirements.
6.3 RF EXPOSURE COMPLIANCE, CONTROL GUIDELINES AND OPERATING
INSTRUCTIONS
To control exposure to yourself and others and to ensure compliance with the RF exposure limits,
always adhere to the following guidelines.
1. Crescend power amplifier products are intended for use in fixed communication locations
(e.g. base station sites). The antenna installation must comply with the following
requirements to ensure optimum performance and compliance with the RF energy
exposure limits required by the FCC.
