Antenna
Use only the supplied integrated antenna. Unauthorized antenna modifications or
attachments could damage the smartphone.
Interference with electronic equipment
Most modern electronic equipment is shielded from radio frequency signals.
However, certain electronic equipment might not be shielded against the radio
frequency signals from your smartphone.
Pacemakers: Consult a physician or the manufacturer of your pacemaker if
you have any questions regarding the effect of radio frequency signals on your
pacemaker. Verify that you are using your smartphone in accordance with the safety
requirements associated with your particular pacemaker, which might include
the following requirements: always keep your smartphone more than 7.88 inches
(20 cm) from the pacemaker when your smartphone is turned on, do not carry
your smartphone in your breast pocket, and use the ear opposite the pacemaker
for making and receiving calls on your smartphone to minimize the potential
interference. If you have any reason to suspect that interference is taking place,
turn off all wireless connections on your smartphone immediately, stop using your
smartphone, and consult a physician.
Hearing aids: Some digital wireless devices might interfere with some hearing aids.
In the event of such interference, consult your wireless service provider or contact
the manufacturer of your hearing aid to discuss alternatives.
Your smartphone includes a magnetometer, which is used by applications such as
the Compass. If an application that uses the magnetometer causes interference with
your hearing aid, close the application.
Other medical devices: If you use any other personal medical device, consult the
manufacturer to determine if your medical device is adequately shielded from
external radio frequency energy. Your physician might be able to assist you in
obtaining this information.
Health care facilities: Turn off all wireless connections on your smartphone in health
care facilities when any regulations posted in these areas instruct you to do so.
Hospitals or health care facilities might be using equipment that could be sensitive
to external radio frequency energy.
Aircraft: Turn off all wireless connections on your smartphone before boarding an
aircraft. The effect of using the smartphone with wireless connections turned on in an
aircraft is unknown. Such use might affect aircraft instrumentation, communication,
and performance, might disrupt the network, might otherwise be dangerous to the
operation of the aircraft, and might be illegal. With all wireless connections on your
smartphone turned off, use only nonradio based device applications in accordance
with airline regulations for electronic devices.
Dangerous areas
Your smartphone is not an intrinsically safe device and is not suitable for use in
hazardous environments, where intrinsically safe devices are required, including
without limitation, in the presence of gas fumes, explosive dust situations, operation of
nuclear facilities, aircraft navigation or communication services, air traffic control, and
life support or weapons systems.
Potentially explosive atmospheres: If you are in any area with a potentially explosive
atmosphere, turn off all wireless connections on your smartphone and obey all signs
and instructions. Sparks in such areas could cause an explosion or fire resulting in
bodily injury or even death.
Areas with a potentially explosive atmosphere are often, but not always, clearly
marked. They include fueling areas such as gasoline or petrol stations; below deck
on boats; fuel or chemical transfer or storage facilities; vehicles using liquefied
petroleum gas, such as propane or butane; areas where the air contains chemicals
or particles, such as grain, dust, or metal powders; and any other area where you
would normally be advised to turn off your vehicle engine.
Do not use the smartphone to report a gas leak in the vicinity of the leak. Leave the
area and make the call from a safe location, if the phone is available and active on
your smartphone.
Blasting areas: When in a "blasting area" or an area that indicates that two-way
radios should be turned off, to avoid interfering with blasting operations, turn off all
wireless connections on your smartphone and obey all signs and instructions.
