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.
