Cleaning and maintenance
• During storage, transportation, and operation of
the device, keep it dry and protect it from collision.
• 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.
• If the device is not going to be used for an extended
period of time, power it off, and remove all cables
connected to it.
• If anything unusual occurs (for example, if the
device emits smoke or any unusual sound or smell),
immediately stop using it, power it off, remove
all cables connected to it, and contact a Huawei
authorized service center.
• Do not trample, pull, or excessively bend any cable.
Doing so may damage the cable, causing the
device to malfunction.
• 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 a Huawei authorized service center
for assistance or repair.
