Huawei C2800 User Manual page 17

Use the AC power supply defined in the specifications of the charger.
An improper power voltage can cause fire or malfunction of the charger.
Do not place any heavy object on the power cord of the charger. Do not
damage, change, or pluck the power cord. Otherwise electric shock or
fire may occur.
When you are charging the battery with the charger, do not touch the
plug, power cord or the charger with a wet hand. Otherwise, electric
shock can be caused.
Once the liquid such as water leaks into the charger, remove the plug of
the charger from the socket immediately. Otherwise, overheating, fire
and other malfunction may occur.
Certification Information (SAR)
THIS DEVICE MEETS THE GOVERNMENT'S REQUIREMENTS FOR
EXPOSURE TO RADIO FREQUENCY ELECTROMAGNETIC FIELD.
Your mobile phone is a low-power radio transmitter and receiver. When it is
turned on, 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 general population. 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 using a mobile
phone. The SAR value is determined at the highest certified power level in
laboratory conditions, but the actual SAR level of the mobile phone while
operating can be well below the value. This is because the mobile phone is
designed to use the minimum power required to reach the network.
All models of Huawei's mobile phone are designed to meet radio frequency
exposure guidelines. Before a phone 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 tests are performed in positions and locations (that is, at the
ear and worn on the body) as required by the FCC for each model. For
