Electronic devices
Most modern electronic equipment is shielded from radio frequency (RF)
signals. However, certain electronic equipment might not be shielded
against the RF signals from your wireless phone. The following four
subsections provide more information about this topic.

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.
Note:
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.

Reference information
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.
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.
