Pacemakers
Pacemaker manufacturers recommend that a minimum separation of 20 cm 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 20 cm 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 minimise 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.
Vehicles
RF signals may affect improperly installed or inadequately shielded electronic systems in
motor vehicles (e.g. electronic fuel injection systems, electronic anti-skid (anti-lock) braking
