Nokia Lumia 822: Safety and Warranty
Chapter 16
The highest SAR value under the ICNIRP guidelines for use of the device
at the ear is 0.79 W/kg.
Use of device accessories may result in different SAR values. SAR values
may vary depending on national reporting and testing requirements
and the network band. Additional SAR information may be provided
under product information at
www.nokia.com
.
Your mobile device is also designed to meet the requirements for expo-
sure to radio waves established by the Federal Communications Com-
mission (USA) and Industry Canada.
These requirements set a SAR limit of 1.6 W/kg averaged over one gram
of tissue. The highest SAR value reported under this standard during
product certification for use at the ear is 1.23 W/kg and when properly
worn on the body is 1.03 W/kg.
Message from the FDA
The U.S. Food and Drug Administration (FDA) provides the following
consumer information about wireless phones.
See
http://www.fda.gov/cellphones
for updated information.
Do wireless phones pose a health hazard?
The available scientific evidence does not show that any health prob
-
lems are associated with using wireless phones. There is no proof, how-
ever, that wireless phones are absolutely safe. Wireless phones emit
low levels of radio frequency energy (RF) in the microwave range while
being used. They also emit very low levels of RF when in the stand-by
mode. Whereas high levels of RF can produce health effects (by heating
tissue), exposure to low level RF that does not produce heating effects
causes no known adverse health effects. Many studies of low level RF
exposures have not found any biological effects. Some studies have
suggested that some biological effects may occur, but such findings
have not been confirmed by additional research. In some cases, other
researchers have had difficulty in reproducing those studies, or in deter
-
mining the reasons for inconsistent results.
What is the FDA’s role concerning the safety of wireless
phones?
Under the law, FDA does not review the safety of radiation emitting
consumer products such as wireless phones before they can be sold,
as it does with new drugs or medical devices. However, the agency
has authority to take action if wireless phones are shown to emit radio
frequency energy (RF) at a level that is hazardous to the user. In such a
case, FDA could require the manufacturers of wireless phones to notify
users of the health hazard and to repair, replace or recall the phones so
that the hazard no longer exists. Although the existing scientific data
do not justify FDA regulatory actions, FDA has urged the wireless phone
industry to take a number of steps, including the following:
• Support needed research into possible biological effects of RF of
the type emitted by wireless phones;
•
Design wireless phones in a way that minimizes any RF exposure to
the user that is not necessary for device function;
•
Cooperate in providing users of wireless phones with the best
possible information on possible effects of wireless phone use on
human health.
FDA belongs to an interagency working group of the federal agencies
that have responsibility for different aspects of RF safety to ensure
coordinated efforts at the federal level.
The following agencies belong to this working group:
•
National Institute for Occupational Safety and Health
•
Environmental Protection Agency
•
Federal Communications Commission
•
Occupational Safety and Health Administration
•
National Telecommunications and Information Administration
The National Institutes of Health participates in some interagency
working group activities, as well.
FDA shares regulatory responsibilities for wireless phones with the
Federal Communications Commission (FCC). All phones that are sold in
the United States must comply with FCC safety guidelines that limit RF
exposure. FCC relies on FDA and other health agencies for safety ques-
