Pacemakers
Pacemaker manufacturers recommend that a minimum distance of 15 cm (6 inches) be maintained
between a wireless phone and a pacemaker to avoid potential interference with the pacemaker.
These recommendations are consistent with the independent research and recommendations of
Wireless Technology Research.
Persons with pacemakers:
• should always keep the phone more than 15 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 potential interference.
If you have any reason to suspect that interference is taking place, switch your phone off immediately.
Other Medical Devices
If you use any other personal medical devices, consult the manufacturer of your device to determine if
it is adequately shielded from external RF energy. Your physician may be able to assist you in obtaining
this information. Switch your phone off 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. 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 require you to do so.
Potentially Explosive Environments
Switch your phone off when in any area with a potentially explosive atmosphere and obey all signs and
instructions. Sparks in such areas could cause an explosion or fire resulting in bodily injury or even death.
Users are advised to switch the phone off while at a refueling point (service station). Users are reminded
of the need to observe restrictions on the use of radio equipment in fuel depots (fuel storage and
distribution areas), chemical plants or where blasting operations are in progress.
