Pacemakers
Pacemaker manufacturers recommend that a minimum separation of 6 inches
(20 cm) should be maintained between a handheld 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 pacemakers:
•
Should always keep the phone more than 6 inches (20 cm) from their
pacemakers 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.
Caution: If you have any reason to suspect that interference is
taking place, switch off your phone immediately.
Hearing aids
Some digital wireless phones could interfere with some hearing aids. In the
event of such interference, you might want to consult your service provider.
Other medical devices
Operation of any radio transmitting equipment, including cellular phones,
could 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. Also
contact these authorities if you have any questions.
Switch off your phone in health care facilities or where any posted regulations
instruct you to do so. Hospitals or health care facilities could be using
equipment that is sensitive to external RF energy.
Vehicles
RF signals could improperly affect installed or inadequately shielded
electronic systems in motor vehicles. These could include electronic fuel
injection systems, electronic anti-skid (anti-lock) braking systems, electronic
speed control systems, or air bag systems.
