Safety Information

This section contains important information about
the operation of your device. It also contains
information about how to use the device safely.
Read this information carefully before using your
device.

Electronic device

Do not use your device if using the device is
prohibited. Do not use the device if doing so causes
danger or interference with other electronic
devices.

Interference with medical equipment

• Follow rules and regulations set forth by hospitals

and health care facilities. Do not use your device
where prohibited.

• Some wireless devices may affect the

performance of hearing aids or pacemakers.
Consult your service provider for more
information.

• Pacemaker manufacturers recommend that

a minimum distance of 15 cm be maintained
between a device and a pacemaker to prevent
potential interference with the pacemaker. If
using a pacemaker, hold the device on the side
opposite the pacemaker and do not carry the

device in your front pocket.

Protecting your hearing when using a headset

•

• Using a headset at high volumes may damage

your hearing. To reduce this risk, lower the
headset volume to a safe and comfortable level.

• Exposure to high volumes while driving may

cause distraction and increase your risk of an
accident.

Areas with flammables and explosives

• Do not use the device where flammables or

explosives are stored (in a gas station, oil depot,
or chemical plant, for example). Using your
device in these environments increases the
risk of explosion or fire. In addition, follow the
instructions indicated in text or symbols.

• Do not store or transport the device in containers

with flammable liquids, gases, or explosives.

Traffic security

• Observe local laws and regulations while using

the device. To reduce the risk of accidents, do not
use your wireless device while driving.

• Concentrate on driving. Your first responsibility is

to drive safely.

To prevent possible hearing damage,
do not listen at high volume levels for
long periods.

• Do not hold the device while driving. Use hands-

free accessories.

• When you must make or answer a call, pull off the

road safely and park the vehicle first.

• RF signals may affect the electronic systems of

motor vehicles. For more information, consult the
vehicle manufacturer.

• Do not place the device over the air bag or in the

air bag deployment area in a motor vehicle. Doing
so may hurt you because of the strong force
when the air bag inflates.

• Do not use your device while flying in an aircraft

or immediately before boarding. Using wireless
devices in an aircraft may disrupt wireless
networks, present a hazard to aircraft operation,
or be illegal.

Operating environment

• Avoid dusty, damp, or dirty environments. Avoid

magnetic fields. Using the device in these
environments may result in circuit malfunctions.

• Do not use your device during thunderstorms to

protect your device against any danger caused
by lightning.

• Ideal operating temperatures are 32 °F to 95°F.

Ideal storage temperatures are -4 °F to 140 °F.
Extreme heat or cold may damage your device or
accessories.

• Do not expose your device to direct sunlight (such

as on a car dashboard) for prolonged periods.

• To protect your device or accessories from fire or

electrical shock hazards, avoid rain and moisture.

• Keep the device away from sources of heat and

fire, such as a heater, microwave oven, stove,
water heater, radiator, or candle.

• Do not place sharp metal objects, such as pins,

near the earpiece or speaker. The earpiece may
attract these objects and result in injury.

• Stop using your device or applications for a while

if the device is overheated. If skin is exposed to
an overheated device for an extended period, low
temperature burn symptoms, such as red spots
and darker pigmentation, may occur.

• Do not use your device's camera flash directly in

the eyes of people or pets. Otherwise temporary
loss of vision or damage to the eyes may occur.

• Do not touch the device's antenna. Otherwise,

communication quality may be reduced.

• Do not allow children or pets to bite or suck the

device or accessories. Doing so may result in
damage or explosion.

• Observe local laws and regulations, and respect

the privacy and legal rights of others.

Child's safety

• Comply with all precautions with regard to child's

safety. Letting children play with the device or
its accessories may be dangerous. The device
includes detachable parts that may present a
choking hazard. Keep away from children.

• The device and its accessories are not intended

for use by children. Children should only use the
device with adult supervision.

Accessories

• Using an unapproved or incompatible power

adapter, charger, or battery may cause fire,
explosion or other hazards.

• Choose only accessories approved for use with

this model by the device manufacturer. The use
of any other types of accessories may void the
warranty, may violate local regulations and laws,
and may be dangerous. Please contact your
retailer for information about the availability of
approved accessories in your area.

Charger safety

• For pluggable devices, the socket-outlet shall

be installed near the devices and shall be easily
accessible.

• Unplug the charger from electrical outlets and

the device when not in use.

• Do not drop or cause an impact to the charger.

• If the power cable is damaged (for example, the

cord is exposed or broken), or the plug loosens,
stop using it at once. Continued use may lead to
electric shocks, short circuits, or fire.

• Do not touch the power cord with wet hands or

pull the power cord to disconnect the charger.

• Do not touch the device or the charger with

wet hands. Doing so may lead to short circuits,
malfunctions, or electric shocks.

• If your charger has been exposed to water,

other liquids, or excessive moisture, take it to an
authorized service center for inspection.

• Ensure that the charger meets the requirements

of Clause 2.5 in IEC60950-1/EN60950-1/
UL60950-1 and has been tested and approved
according to national or local standards.

• Connect the device only to products with the

USB-IF logo or with USB-IF compliance program
completion.

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 skin
or eyes. If the electrolyte touches your skin 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

• Do not drop the device or battery. If the device or

battery is dropped, especially on a hard surface, it
may be damaged.

• Use the battery only with a charging system that

is IEEE-Std-1725 standard qualified. The use of
an unqualified battery or charger may lead to fire,
explosion, leakage, or other hazards.

• Replace the battery only with an IEEE-Std-1725

standard qualified battery. The use of an
unqualified battery may lead to fire, explosion,
leakage, or other hazards.

• 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.
