Pacemakers
Pacemaker manufacturers recommend that a minimum separation of 20 cm
(6 inches) be maintained between a hand-held wireless phone and a pace-
maker to avoid potential interference with the pacemaker. These recommen-
dations 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 de-
vices. Consult a physician or the manufacturer of the medical device to de-
termine 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 electron-
ic systems in motor vehicles (e.g. electronic fuel injection systems, electronic
anti-skid (anti-lock) braking systems, electronic speed control systems, air
bag systems).
Check with the manufacturer or its representative regarding your vehicle.
You should also consult the manufacturer of any equipment that has been
added to your vehicle.
