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, 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
sa f el y.
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.

For more information, consult the vehicle manufacturer.
In a motor vehicle, do not place the device over the air bag or
13
Page 14
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
your device before boarding an aircraft. Using wireless
devices in an aircraft may cause danger to the operation of
the aircraft and disrupt the wireless telephone network. It
may also be considered illegal.

components. Keep your device 1.5 cm away from your body
to meet the requirement earlier mentioned.
On a stormy day with thunder, do not use your device when it
is being charged, to prevent any danger caused by lightning.
When you are on a call, do not touch the antenna. Touching
the antenna affects the call quality and results in increase in
power consumption. As a result, the talk time and the
standby time are reduced.
While using the device, observe the local laws and
regulations, and respect others' privacy and legal rights.
Keep the ambient temperature between 0°C and 45°C while

16
Page 17
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 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.
