Battery safety
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.
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.
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.
Do not put batteries in fire as they may explode. Damaged batteries may also explode.
Dispose of used batteries in accordance with local regulations. Improper battery use may
lead to fire, explosion, or other hazards.
Do not allow children or pets to bite or suck the battery. Doing so may result in damage or
explosion.
Do not smash or pierce the battery, or expose it to high external pressure. Doing so may
lead to a short circuit or overheating.
Cleaning and maintenance
Keep the device and accessories dry. Do not attempt to dry it with an external heat
source, such as a microwave oven or hair dryer.
Do not expose your device or accessories to extreme heat or cold. These environments
may interfere with proper function and may lead to fire or explosion.
Avoid collision, which may lead to device malfunctions, overheating, fire, or explosion.
Do not use any chemical detergent, powder, or other chemical agents (such as alcohol
and benzene) to clean the device or accessories. These substances may cause damage
to parts or present a fire hazard. Use a clean, soft, and dry cloth to clean the device and
accessories.
Do not dismantle or remanufacture the device and its accessories. This voids the warranty
and releases the manufacturer from liability for damage. In case of damage, contact a
Huawei authorized service center for assistance or repair.
