deployment area.
Potentially explosive environments
Switch off your device in any area with a potentially explosive atmo-
sphere, for example near gas pumps at service stations. Sparks in such
areas could cause an explosion or fi re resulting in bodily injury or death.
Observe restrictions in fuel service stations, storage, and distribution
areas; chemical plants; or where blasting operations are in progress.
Areas with a potentially explosive atmosphere are often, but not always,
clearly marked. They include areas where you would be advised to turn
off your vehicle engine, below deck on boats, chemical transfer or stor-
age facilities and where the air contains chemicals or particles such as
grain, dust, or metal powders. You should check with the manufacturers
of vehicles using liquefi ed petroleum gas (such as propane or butane) to
determine if this device can be safely used in their vicinity.
Certifi cation information (SAR)
This mobile device meets guidelines for exposure to radio waves. Your
mobile device is a radio transmitter and receiver. It is designed not to
exceed the limits for exposure to radio waves recommended by interna-
tional guidelines. These guidelines were developed by the independent
scientifi c organization ICNIRP and include safety margins designed to
assure the protection of all persons, regardless of age and health.
The exposure guidelines for mobile devices employ a unit of measure-
ment known as the Specifi c Absorption Rate or SAR. The SAR limit
stated in the ICNIRP guidelines is 2.0 watts/kilogram (W/kg) averaged
over 10 grams of tissue. Tests for SAR are conducted using standard
operating positions with the device transmitting at its highest certifi ed
power level in all tested frequency bands. The actual SAR level of an
operating device can be below the maximum value because the device
is designed to use only the power required to reach the network. That
amount changes depending on a number of factors such as how close
you are to a network base station.
The highest SAR value under the ICNIRP guidelines for use of the device
at the ear is 0.79 W/kg.
Chapter 18
Use of device accessories may result in diff erent 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 certifi cation 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 scientifi c 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 eff ects (by heating
tissue), exposure to low level RF that does not produce heating eff ects
causes no known adverse health eff ects. Many studies of low level RF
exposures have not found any biological eff ects. Some studies have
suggested that some biological eff ects may occur, but such fi ndings
have not been confi rmed by additional research. In some cases, other
researchers have had diffi culty 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
