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 depends on the type of the 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 you are requested to do 
so in hospitals, clinics or healthcare 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.
