• 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.
• 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.
• Do not modify or remanufacture, attempt to insert foreign objects into the battery, immerse or
expose to water or other liquids, expose to fire, explosion or other hazard.
• Avoid dropping the device or battery. If the device or battery is dropped, especially on a hard
surface, and the user suspects damage, take it to a qualified service center for inspection.

Cleaning and Maintenance
• The device, battery, and charger are not water-resistant. Keep them dry. Protect the device,
battery, 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 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
temperature. Otherwise, they may not function properly and may lead to a fire or an explosion.
When the temperature is lower than 0°C, performance of the battery is affected.
• 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.
• Before you clean or maintain the device, power off the device and disconnect it from the
charger.
