Pacemakers
Pacemaker manufacturers recommend that a minimum separation of 20 
cm (6 inches) be maintained between a hand-held wireless phone and a 
pacemaker to avoid potential interference with the pacemaker. These 
recommendations are consistent with the independent research by and 
recommendations of Wireless Technology Research.
Persons with pacemaker:
• Should always keep the phone more than 20 cm (6 inches) from their 
pacemaker when the phone is switched on;
• Should not carry the phone in a breast pocket;
• Should use the ear opposite the pacemaker to minimize the potential 
for interference.
• If you have any reason to suspect that interference is taking place, 
switch off your phone immediately.
Hearing Aids
Some digital wireless phones may interfere with some hearing aids. In the 
event of such interference, you may want to consult your service provider.
Other Medical Devices
Operation of any radio transmitting equipment, including cellular phones, 
may interfere with the functionality of inadequately protected medical 
devices. Consult a physician or the manufacturer of the medical device to 
determine if they are adequately shielded from external RF energy or if 
you have any questions.
Switch off your phone in health care facilities when any regulations 
posted in these areas instruct you to do so. Hospitals or health care 
facilities may be using equipment that could be sensitive to external RF 
energy.
