Cleaning and Maintenance
battery may be short-circuiting and may cause injuries and 
burns on your body.
• Do not disassemble the battery or solder the battery poles. 
Otherwise, it may lead to electrolyte leakage, overheating, 
fire, or explosion.
• 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.
• Danger of explosion if battery is incorrectly replaced. 
Recycle or dispose of used batteries according to the local 
regulations or reference instruction supplied with your 
device.
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. 
						

							Emergency Call

• Do not place your device, battery, or charger in places 
where it 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. 
• Do not use any chemical detergent, powder, or other 
chemical agents (such as alcohol and benzene) to clean 
the device and the charger. Otherwise, parts of the device 
may get damaged or a fire can be caused. You can clean 
the device and the charger with a piece of damp and soft 
antistatic cloth.
• Do not dismantle the device or accessories. Otherwise, the 
warranty on the device and accessories is invalid and the 
manufacturer is not liable to pay for the damage.

Certification Information (SAR)
conditions. You should not rely solely on the device for essential 
communications.
Certification Information (SAR)
This mobile device meets guidelines for exposure to radio 
waves.
Your device is a low-power radio transmitter and receiver. As 
recommended by international guidelines, the mobile device is 
designed not to exceed the limits for exposure to radio waves. 
These guidelines were developed by the independent scientific 
organization International Commission on Non-Ionizing Radia-
tion Protection (ICNIRP) and include safety measures designed 
to ensure safety for 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 of the device when being operated 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 USA and Canada is 1.6 watts/kilo-
gram (W/kg) averaged over one gram of tissue. The highest 
SAR value reported to the FCC and IC for this device type when 
tested for use at the ear is 0.853 W/kg, and when properly worn 
on the body is 0.778 W/kg.
The SAR limit also adopted by Europe is 2.0 W/kg averaged 
over 10 grams of tissue. The highest SAR value for this device 
type when tested at the ear is 0.761 W/kg, and when properly 
worn on the body is 0.576 W/kg.

FCC Statement
This equipment has been tested and found to comply with the 
limits for a Class B digital device, pursuant to Part 15 of the FCC 
Rules. These limits are designed to provide reasonable protec-
tion against harmful interference in a residential installation. This 
equipment generates, uses and can radiate radio frequency 
energy and, if not installed and used in accordance with the 
instructions, may cause harmful interference to radio communi-
cations. However,there is no guarantee that interference will not 
occur in a particular installation.If this equipment does cause 
harmful interference to radio or television reception,which can 
be determined by turning the equipment off and on, the user is 
encouraged to try to correct the interference by one or more of 
the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and 
receiver.
• Connect the equipment into an outlet on a circuit different 
from that to which the receiver is connected.
• Consult the dealer or an experienced radio/TV technician 
for help.
This device complies with Part 15 of the FCC Rules. Operation 
is subject to the following two conditions: (1) this device may not 
cause harmful interference, and (2) this device must accept any 
interference received, including interference that may cause 
undesired operation.
Warning: Changes or modifications made to this device not 
expressly approved by Huawei Technologies Co., Ltd. may void 
the FCC authorization to operate this device.
