Electronic devices
Most modern electronic equipment is
shielded from RF signals. However, cer-
tain electronic equipment may not be
shielded against the RF signals from
your mobile phone.
Pacemakers
The Health Industry Manufacturers As-
sociation recommends that a minimum
separation of 2.5 cm be maintained 
between a handheld mobile phone 
and a pacemaker to avoid potential 
interference with the pacemaker. 
These recommendations are consistent
with the independent research by and
recommendations of Wireless Tech-
nology Research.
Persons with pacemakers:
- Should always keep the phone more
than 2.5 cm from their pacemaker
when the phone is turned on.
- Should not carry the phone in a breast
pocket.
- Should use the ear opposite the pace-
maker to minimize the potential for 
interference.
- If you have any reason to suspect that
interference is taking place, turn your
phone off immediately.
Hearing aids
Some digital mobile phones may inter-
fere with some hearing aids. In the
event of such interference, you may
want to consult your network operator
or service provider or call the customer
service line to discuss alternatives. 
Other medical devices
If you use any other personal medical
device, consult the manufacturer of
your device to determine if it is 
adequately shielded from external RF
signals. Your physician may be able to 
assist you in obtaining this information.
Turn your phone off in health care facil-
ities when any regulations posted in
these areas instruct you to do so. 
Hospitals or health care facilities may
be using equipment that could be sen-
sitive to external RF signals.
Potentially explosive atmospheres
Turn your phone off when in any area
with a potentially explosive atmosphere
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 potentially explosive atmo-
sphere are often but not always clearly
marked. They include fuelling areas
such as petrol stations, below deck on
boats, fuel or chemical transfer or stor-
age facilities, vehicles using liquefied
petroleum gas (such as propane or bu-
tane), 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.
Airbags
An airbag inflates with great force. 
Do not place objects, including in-
stalled or portable mobile equipment in
the area over the airbag or in the airbag
deployment area. If in-vehicle mobile
equipment is improperly installed and
the airbag inflates, serious injury could
result.
