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
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.
