Warnings and Precautions 18
● Do not connect two poles of the battery with conductors, such as metal materials, keys,
or jewelries. Otherwise, the battery may be short-circuited and may cause injuries and
burns on your body.
● Do not disassemble the battery or solder the battery poles. Otherwise, it may lead to
electrolyte leakage, overheating, fire, or explosion.
● If battery electrolyte leaks out, ensure that the electrolyte does not touch your skin and
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 battery deformation, color change, or abnormal heating while you
charge or store the battery, remove the battery immediately and stop using it. Otherwise,
it may lead to battery leakage, overheating, 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 batteries in fire as they may explode. Batteries may also explode if
damaged.
● Danger of explosion if battery is incorrectly replaced. Recycle or dispose of used
batteries according to the local regulations or reference instruction supplied with your
device.
Cleaning and Maintenance
● The device, battery, and charger are not water-resistant. Keep them dry. Protect the

with a wet hand. Otherwise, it may lead to a short circuit, a malfunction of the device,
and an electric shock to the user.
● Do not place your device, battery, and charger in places where they can get damaged
because of collision. Otherwise, it may lead to battery leakage, device malfunction,
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 stored on them.
● Do not leave your device, battery, and charger in a place with an extreme high or low

explosion.
● Do not place sharp metal objects such as pins near the earpiece. The earpiece may
attract these objects and hurt you when you are using the device.
