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.
