Care must be taken when using the phone in close 

proximity to personal medical devices, such as 

pacemakers and hearing aids.

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.

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.

Please consult your doctor and the device manufacturer 

to determine if operation of your phone may interfere 

with the operation of your medical device.

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.

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.

Please note that because of possible interference to 

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.
