• Do not solder battery poles or dismantle the battery. Doing so may lead to
electrolyte leakage, excessive heat, fire, or explosion.
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.
• Before you clean or maintain the device, stop using it, stop all applications, and
disconnect all cables connected to it.
• 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 place magnetic stripe cards, such as credit cards and phone cards, near the
device for extended periods of time. Otherwise the magnetic stripe cards may be
damaged.
• 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 an authorized service center for assistance or repair.
• If the device screen is broken in a collision, immediately stop using the device. Do
not touch or attempt to remove the broken parts. Promptly contact an authorized
service center.
Emergency calls
The availability of emergency calls is subject to your cellular network quality, service
provider policy, and local laws and regulations. Never rely solely on your device for
critical communications like medical emergencies.
Environmental protection
• The device and its accessories (if included), such as the power adapter, headset,
and battery should not be disposed of with household garbage.
