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
Switch 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
Switch 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 on board 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 to electronic
equipment, some vehicle manufacturers forbid the use of mobile phones
in their vehicles unless a handsfree kit with an external antenna is
included in the installation.
