eyes. When the electrolyte touches your skin or splashes into your eyes, wash your eyes with
clean water immediately and consult a doctor.
• If there is a case of ba+ery deforma[on, color change, or abnormal hea[ng while you
charge or store the ba+ery, remove the ba+ery immediately and stop using it.
Otherwise, it may lead to ba+ery leakage, overhea[ng, explosion, or fire.
• If the power cable is damaged (for example, the cord is exposed or broken), or the plug
loosens, stop using the cable at once. Otherwise, it may lead to an electric shock, a short circuit
of the charger, or a fire.
• Do not dispose of ba+eries in fire as they may explode. Ba+eries may also explode if
damaged.
• Do not modify or remanufacture, a+empt to insert foreign objects into the ba+ery,
immerse or expose to water or other liquids, expose to fire, explosion or other hazard.
• Avoid dropping the device or ba+ery. If the device or ba+ery is dropped, especially on a
hard surface, and the user suspects damage, take it to a qualified service center for inspec[on.
• Improper ba+ery use may result in a fire, explosion or other hazard.
• Promptly dispose of used ba+eries in accordance with local regula[ons.
• The device should only be connected to products that bear the USB-‐IF logo or have
completed the USB-‐IF compliance program.
• Only use the ba+ery with a charging system that has been qualified with the system per
this standard, IEEE-‐Std-‐1725-‐2006. Use of an unqualified ba+ery or charger may present a risk of
fire, explosion, leakage, or other hazard.
• Replace the ba+ery only with another ba+ery that has been qualified with the system per
this standard, IEEE-‐Std-‐1725-‐2006. Use of an unqualified ba+ery may present a risk of fire,
explosion, leakage or other hazard.
Cleaning and Maintenance
• The device, ba+ery, and charger are not water-‐resistant. Keep them dry. Protect the
device, ba+ery, and charger from water or vapor. Do not touch the device or the charger with a
wet hand. Otherwise, it may lead to a short circuit, a malfunc[on of the device, and an electric
shock to the user.
• Do not place your device, ba+ery, and charger in places where they can get damaged
because of collision. Otherwise, it may lead to ba+ery leakage, device malfunc[on, overhea[ng,
fire, or explosion.
• Do not place magne[c storage media such as magne[c cards and floppy disks near the
device. Radia[on from the device may erase the informa[on stored on them.
• Do not leave your device, ba+ery, and charger in a place with an extreme high or low
temperature. Otherwise, they may not func[on properly and may lead to a fire or an explosion.
When the temperature is lower than 0°C, performance of the ba+ery is affected.
• Do not place sharp metal objects such as pins near the earpiece. The earpiece may a+ract
these objects and hurt you when you are using the device.
• Before you clean or maintain the device, power off the device 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 and the charger. Otherwise, parts of the device may be damaged or
a fire can be caused. You can clean the device and the charger with a piece of damp and sog
an[sta[c cloth.
• Do not dismantle the device or accessories. Otherwise, the warranty on the device and
accessories is invalid and the manufacturer is not liable to pay for the damage.
• If the device screen is broken by colliding with hard objects, do not touch or try to remove
the broken part. In this case, stop using the device immediately, and then contact an authorized
service center in [me.
Emergency Call
You can use your device for emergency calls in the service area. The connec[on, however,
