Charger
Use the charger approved by the phone manufacturer only.
Any violation of this rule may result in fire or malfunction of
the charger.
Do not short-circuit the charger. Short-circuiting the
charger may cause fire or malfunction of the charger.
If the power cord is damaged (for example, the lead is
exposed or broken), or the plug becomes loose, stop
using the cable at once. Otherwise, electric shock,
short-circuit of the charger, or fire may occur.
Keep the charger dry. Once water or other liquid leaks into
the charger, electrical leakage or other faults may occur.
Do not use the charger in a dusty and damp environment.
Keep the power cord away from any heating appliance.
Ensure the charger is properly plugged into the power
socket properly when charging the battery. Improper
insertion may result in electric shock, fire, or explosion. To
unplug the charger, pull the plug off rather than tear the
power cord.
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
