Charger safety
• Unplug the charger from electrical outlets and the device when
not in use.
• Do not drop or cause an impact to the charger.
• Do not touch the power cord with wet hands or pull the power
cord to disconnect the charger.
• If the power cable is damaged (for example, the cord is exposed
or broken), or the plug loosens, stop using it at once. Continued
use may lead to electric shocks, short circuits, or fire.
• If your device has been exposed to water, other liquids, or
excessive moisture, take it to an authorized service center for
inspection.
• Connect the device only to products with the USB-IF logo or with
USB-IF compliance program completion.
• For pluggable devices, the socket-outlet shall be installed near
the devices and shall be easily accessible.
Battery safety
• Do not connect battery poles with conductors, such as keys,
jewelry, or other metal materials. Doing so may short-circuit the
battery and cause injuries or burns.

• Do not solder battery poles or dismantle the battery. Doing so
may lead to electrolyte leakage, excessive heat, fire, or
explosion.
• Do not attempt to modify or remanufacture the battery, insert
foreign objects into it, or immerse or expose it to water or other
liquids. Doing so may lead to fire, explosion, or other hazards.
• Keep the battery away from excessive heat and direct sunlight.
Do not place it on or in heating devices, such as microwave
ovens, stoves, or radiators. Batteries may explode if overheated.
• If the battery leaks, ensure that the electrolyte does not make
direct contact with your skins or eyes. If the electrolyte touches
your skins or splashes into your eyes, immediately flush with
clean water and consult a doctor.
• In case of battery deformation, color change, or overheating
while charging or storing, immediately stop using the device and
remove the battery. Continued use may lead to battery leakage,
fire, or explosion.
• Do not put batteries in fire as they may explode. Damaged
batteries may also explode.
• Do not drop the device or battery. If the device or battery is
dropped, especially on a hard surface, and may be damaged,
take it to an authorized service center for inspection.
• Improper battery use may lead to fire, explosion, or other
hazards.

Using or charging your device in these environments may result
in circuit malfunctions.
• Do not use your device during thunderstorms to protect your
device against any danger caused by lightning.
• Observe local laws and regulations, and respect the privacy and
legal rights of others.
• Avoid touching the antenna when you are on a call. Touching the
antenna affects call quality, increases power consumption, and
reduces talk and standby time.
• Ideal operating temperatures are 0 °C to 45 °C. Ideal storage
temperatures are 0 °C to 45 °C. Extreme heat or cold may
damage your device or accessories.
• Do not expose your device to direct sunlight (such as on a car
dashboard) for prolonged periods.
• Do not place your device or batteries on or in heating devices,
such as microwave ovens, stoves, water heaters, or radiators.
Batteries may explode if overheated.
• Stop using your device or applications for a while if the device is
overheated. If skin is exposed to an overheated device for an
extended period, low temperature burn symptoms, such as red
spots and darker pigmentation, may occur.
• If your device has a camera flash, do not use it directly in the eyes
of people or pets. Otherwise temporary loss of vision or damage
to the eyes may occur.
• Do not allow children or pets to bite or suck the device or battery.
Doing so may result in damage or explosion.

Protecting your hearing when using a headset
•
To prevent possible hearing damage, do not listen at high
volume levels for long periods.
• Using a headset at high volumes may damage your hearing. To
reduce this risk, lower the headset volume to a safe and
comfortable level.
• Exposure to high volumes while driving may cause distraction
and increase your risk of an accident.
Child's safety
• Comply with all precautions with regard to child's safety. Letting
children play with the device or its accessories may be
dangerous. The device includes detachable parts that may
present a choking hazard. Keep away from children.
• The device and its accessories are not intended for use by
children. Children should only use the device with adult
supervision.
Interference with medical equipment
• Follow rules and regulations set forth by hospitals and health
care facilities. Do not use your device where prohibited.
• Pacemaker manufacturers recommend that a minimum
distance of 15 cm be maintained between a device and a
pacemaker to prevent potential interference with the pacemaker.
If using a pacemaker, hold the device on the side opposite the
pacemaker and do not carry the device in your front pocket.
• Some wireless devices may affect the performance of hearing
aids or pacemakers. Consult your service provider for more
information.

Areas with flammables and explosives
• Do not use the device where flammables or explosives are
stored (in a gas station, oil depot, or chemical plant, for example).
Using your device in these environments increases the risk of
explosion or fire. In addition, follow the instructions indicated in
text or symbols.

• When you must make or answer a call, pull of the road safely and
park the vehicle first.
• RF signals may affect the electronic systems of motor vehicles.
For more information, consult the vehicle manufacturer.
• Do not place the device over the air bag or in the air bag
deployment area in a motor vehicle. Doing so may hurt you
because of the strong force when the air bag inflates.
• Do not use your device while flying in an aircraft. Power off your
device before boarding. Using wireless devices in an aircraft may
disrupt wireless networks, present a hazard to aircraft operation,
or be illegal.
Cleaning and maintenance
• Before you clean or maintain the device, power it off, and
disconnect it from the charger.
• Do not use any chemical detergent, powder, or other chemical
agents (such as alcohol and benzene) to clean the device or
charger. These substances may cause damage to parts or
present a fire hazard. Use a clean, soft, and dry cloth to clean the
device and charger.

• Keep the device and accessories dry. Protect them from water
and humidity. Do not touch the device or the charger with wet
hands. Doing so may lead to short circuits, malfunctions, or
electric shocks.
• Avoid collision, which may lead to battery leakage, device
malfunctions, overheating, fire, or explosion.
• Do not place magnetic storage media, such as magnetic cards
and floppy disks, near the device. Radiation from the device may
erase the information on magnetic storage media.
• Do not expose your device, battery, or charger to extreme heat
or cold. These environments may interfere with proper function
and may lead to fire or explosion. Battery performance is affected
at temperatures lower than 0°C.
