service stations. Sparks in such areas
could cause an explosion or fire
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 switch
your vehicle engine off, below deck on
boats, chemical transfer or storage
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 liquefied petroleum
gas (such as propane or butane) to
determine if this device can be safely
used in their vicinity.
Certification 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 international
guidelines. These guidelines were
developed by the independent
scientific organisation 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
measurement known as the Specific
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 certified 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 0.93 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
