opposite side of the pacemaker and do not carry the device in
your front pocket.
Potentially Explosive Atmosphere
Power off your device in any area with a potentially explosive
atmosphere, and comply with all signs and instructions. Areas that
may have potentially explosive atmospheres include the areas
where you would normally be advised to turn off your vehicle
engine. Triggering of sparks in such areas could cause an
explosion or a fire, resulting in bodily injuries or even deaths. Do
not power on your device at refueling points such as service
stations. Comply with restrictions on the use of radio equipment in
fuel depots, storage, and distribution areas, and chemical plants.
In addition, adhere to restrictions in areas where blasting
operations are in progress. Before using the device, watch out for
areas that have potentially explosive atmospheres that are often,
but not always, clearly marked. Such locations include areas below
the deck on boats, chemical transfer or storage facilities, and areas
where the air contains chemicals or particles such as grain, dust,
29
or metal powders. Ask the manufacturers of vehicles using
liquefied petroleum gas (such as propane or butane) whether this
device can be safely used in their vicinity.
Traffic Security
Observe local laws and regulations while using the device. In
addition, if using the device while driving a vehicle, comply with
the following guidelines:

Concentrate on driving. Your first responsibility is to drive safely.

Do not talk on the device while driving. Use hands-free
accessories.

When you have to make or answer a call, park the vehicle at
the road side before using your device.

RF signals may affect electronic systems of motor vehicles. For
more information, consult the vehicle manufacturer.

In a motor vehicle, do not place the device over the air bag or
in the air bag deployment area. Otherwise, the device may hurt
you owing to the strong force when the air bag inflates.

Do not use your device while flying in an aircraft. Power off

accessories of other manufacturers or vendors with this device
model may invalidate any approval or warranty applicable to the
device, result in the non-operation of the device, and cause danger.
Battery and Charger

Unplug the charger from the electrical plug and the device
when not in use.

The battery can be charged and discharged hundreds of times
before it eventually wears out. When the standby time and the
talk time are shorter than the normal time, replace the battery.

Use the AC power supply defined in the specifications of the
charger. An improper power voltage may cause a fire or a
malfunction of the charger.

Do not connect two poles of the battery with conductors, such
as metal materials, keys, or jewelries. Otherwise, the battery
may be short-circuited 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
32
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.
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.

Do not place your device, battery, and charger in places where
they 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
33
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 be 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.
Emergency Call
You can use your device for emergency calls in the service area.
The connection, however, cannot be guaranteed in all conditions.
You should not rely solely on the device for essential
communications.

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 independent scientific
organization International Commission on Non-Ionizing Radiation
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/kilogram
(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 1.080/kg, and when properly worn on the body is
0.569 W/kg.
