Radio Frequency Interference

General Statement on Interference
Care must be taken when using the phone in close proximity to personal medical devices,
such as pacemakers and hearing aids.
Pacemakers
Pacemaker manufacturers recommend that a minimum separation of 15 cm be
maintained between a mobile phone and a pacemaker to avoid potential interference
with the pacemaker. To achieve this, use the phone on the opposite ear to your
pacemaker and do not carry it in a breast pocket.
Hearing Aids
People with hearing aids or other cochlear implants may experience interfering noises
when using wireless devices or when one is nearby. The level of interference will depend
on the type of hearing device and the distance from the interference source. Increasing
the separation between them may reduce the interference. You may also consult your
hearing aid manufacturer to discuss alternatives.
Medical Devices
Please consult your doctor and the device manufacturer to determine if operation of your
phone may interfere with the operation of your medical device.
Hospitals
Turn off your wireless device when requested to do so in hospitals, clinics or health care
facilities. These requests are designed to prevent possible interference with sensitive
medical equipment.

Aircraft
Turn off your wireless device whenever you are instructed to do so by airport or airline
staff. Consult the airline staff about the use of wireless devices onboard the aircraft. If
your device offers a 'flight mode' , this must be enabled prior to boarding an aircraft.
Interference in Cars
Please note that because of possible interference with electronic equipment, some
vehicle manufacturers forbid the use of mobile phones in their vehicles unless a hands-
free kit with an external antenna is included in the installation.

Explosive Environments

Gas Stations and Explosive Atmospheres
In locations with potentially explosive atmospheres, obey all posted signs to turn off
wireless devices such as your phone or other radio equipment. Areas with potentially
explosive atmospheres include fueling areas, below decks on boats, fuel or chemical
transfer or storage facilities, areas where the air contains chemicals or particles, such as
grain, dust, or metal powders.
Blasting Caps and Areas
Power off your mobile phone or wireless device when in a blasting area or in areas posted
power off "two-way radios" or "electronic devices" to avoid interfering with blasting operations.
