Certification Information
(SAR)
THIS DEVICE MEETS THE
GOVERNMENT'S REQUIREMENTS FOR
EXPOSURE TO RADIO FREQUENCY
ELECTROMAGNETIC FIELD.
Your wireless device is a low-power radio
transmitter and receiver. When it is running, it
emits low levels of radio frequency energy
(also known as radio waves or radio frequency
fields).
Governments around the world have adopted
comprehensive international safety guidelines,
developed by scientific organizations, e.g.
ICNIRP (International Commission on
4
Non-Ionizing Radiation Protection) and IEEE
(Institute of Electrical and Electronics
Engineers Inc.), through periodic and thorough
evaluation of scientific studies. These
guidelines establish permitted levels of radio
wave exposure for the public. The levels
include a safety margin designed to assure the
safety of all persons, regardless of age and
health, and to account for any variations in
measurements.
Specific Absorption Rate (SAR) is the unit of
measurement for the amount of radio frequency
energy absorbed by the body when you use a
wireless device. The SAR value is determined
at the highest certified power level in
laboratory conditions, but the actual SAR level
of the wireless device while operating can be
well below the value. This is because the
wireless device is designed to use the minimum
power required to reach the network.
All models of Huawei's wireless device are
designed to meet radio frequency exposure
guidelines such as European Council
Recommendation and Federal Communications
Commission Notice (United States).
European Council Recommendation: Before
a wireless device model is available for sale to
the public, it must be tested according to the
technical standard-EN 50361 and not exceed
the limit established by the European Council
Recommendation: 1999/519/EC for safe
exposure.
The SAR limit adopted by the 1999/519/EC is
2.0 watts/kilogram (W/kg) averaged over ten
gram of tissue.
[EN 50361 scope states "This basic standard
applies to any electromagnetic field (EM)
transmitting devices intended to be used with
the radiating part of the equipment in close
proximity to the human ear including mobile
phones, cordless phones, etc. The frequency
range is 300 MHz to 3 GHz. Therefore, the
above text does not address primary use of the
wireless device product.]
Federal Communications Commission
Notice (United States): Before a wireless
device model is available for sale to the public,
it must be tested and certified to the FCC that it
does not exceed the limit established by the
government-adopted requirement for safe
exposure.
The SAR limit adopted by the USA and Canada
is 1.6 watts/kilogram (W/kg) averaged over one
gram of tissue. [There is no reference to the
specific reference standard or its applicability
to the intended use of the product.]
