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.

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.
