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. Please consult your doctor and the device
manufacturers to determine if the operation of your phone may interfere with the
operation of your medical devices.
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 Equipment
Turn off your wireless device when requested to do so in hospitals, clinics or healthcare
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 airplane mode, this must be enabled prior to boarding an aircraft.
