Electronic Devices
Most modern electronic equipment is shielded from
radio frequency (RF) signals. However, certain
electronic equipment may not be shielded against
the RF signals from your mobile phone.
Pacemakers
Pacemaker manufacturers recommend that a
minimum separation of 6 inches (20 cm) be
maintained between a hand-held mobile 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 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 mobile 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 (for example, 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.
Posted Facilities
Switch your phone off in any facility where posted
notices so require.
