Battery safety

Do not connect battery poles with conductors, such as keys, jewelry, or other
metal materials. Doing so may short-circuit the battery and cause injuries or
burns.

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.

In case of battery deformation, color change, or overheating while charging or
storing, immediately stop using the device and remove the battery. Continued
use may lead to battery leakage, fire, or explosion.

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.

Do not drop the device or battery. If the device or battery is dropped, especially
on a hard surface, and may be damaged.

If the device standby time shortens significantly, replace the battery.

When the device has a built-in, non-removable battery, do not attempt to remove
the battery, otherwise the device may be damaged. To replace the battery, take
the device to an authorized service center.
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.
Disposal and recycling information
This symbol (with or without a solid bar) on the device, batteries (if
included), and/or the packaging, indicates that the device and its electrical
accessories (for example, a headset, adapter, or cable) and batteries should not be
disposed of as household garbage. These items should not be disposed of as
unsorted municipal waste and should be taken to a certified collection point for
recycling or proper disposal.
For more detailed information about device or battery recycling, contact your local
city office, household waste disposal service, or retail store.
Disposal of the device and batteries (if included) is subject to WEEE Directive
Recast (Directive 2012/19/EU) and Battery Directive (Directive 2006/66/EC). The
purpose of separating WEEE and batteries from other waste is to minimize the
potential environmental impacts and human health risk of any hazardous
substances that may be present.
Reduction of hazardous substances
This device is compliant with the REACH Regulation [Regulation (EC) No
1907/2006] and RoHS Directive Recast (Directive 2011/65/EU). Batteries (if
included) are compliant with the Battery Directive (Directive 2006/66/EC). For

EU regulatory conformance
RF exposure requirements
Important safety information regarding radio frequency (RF) radiation exposure:
RF exposure guidelines require that the device be used at a minimum of 1.5 cm
from the human body. Failure to observe this guideline may result in RF exposure
exceeding limits.
Certification information (SAR)
This device meets guidelines for exposure to radio waves.
Your device is a low-power radio transmitter and receiver. As recommended by
international guidelines, the device is designed not to exceed the limits for exposure
to radio waves. These guidelines were developed by the International Commission
on Non-Ionizing Radiation Protection (ICNIRP), an independent scientific
organization, and include safety measures designed to ensure the safety of all
users, regardless of age and health.
The Specific Absorption Rate (SAR) is the unit of measurement for the amount of
radio frequency energy absorbed by the body when using a device. The SAR value
is determined at the highest certified power level in laboratory conditions, but the
actual SAR level during operation can be well below the value. This is because the
device is designed to use the minimum power required to reach the network.
The SAR limit adopted by Europe is 2.0 W/kg averaged over 10 grams of tissue,
and the highest SAR value for this device complies with this limit.
Statement
Hereby, Huawei Technologies Co., Ltd. declares that this device is in compliance
with the essential requirements and other relevant provisions of Directive
