Agency/Regulatory Information
The wireless device is approved for use in many regions of the world. In
these regions, the device meets all radio frequency exposure requirements.
The following approvals and notices apply in specific regions as noted.
CE Approval (European Union)
The wireless device is approved to be used in the member states of the EU.
Huawei declares that the wireless device is in compliance with the essential
requirements and other relevant provisions of the Radio and
Telecommunications Terminal Equipment Directive 1999/5/EC (R&TTE
Directive).
Radio Frequency Exposure
To ensure compliance at all times with the R&TTE Directive* 1999/5/EC,
the wireless device can be held in the hand but still requires a minimum
distance of 1.5 cm from the body when in operation.
* The general public RF exposure limits referenced in the R&TTE Directive
are consistent with the published Guidelines of the International
Commission on Non-Ionizing Radiation Protection (ICNIRP) 1998. ICNIRP
is a formally recognized non-governmental organization in Non-Ionising
Radiation Protection for the World Health Organisation (WHO), the
International Labour Organisation (ILO) and the European Union (EU). For
more information, visit the ICNIRP website at www.icnirp.de.
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 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.

10
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.]
