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 (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 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 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 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.
