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 Non-Ionizing Radiation Protection) and IEEE (Institute of
Electrical and Electronics Enginee rs 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 fo r
any variations in measurements.
Specific Absorption Rate (SAR) is the unit of measurement for the amount of
radio frequency energy absorbed by the body wh en using 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 frequenc y
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 does not exceed the limit established by the European
Council Recommendation: 1999 /519/EC for safe exposure. l.
The SAR limit adopted by the 1999/519/EC is 2.0 watts/kilogram (W/kg)
