Some digital wireless phones may interfere
with some hearing aids. In the event of such
interference, you may want to consult your
network operator.
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.
Posted facilities:
Switch your phone off in any facility where
posted notices so require.
Potentially explosive atmospheres:
Switch off your phone 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 off the phone
when at a refuelling point (service station).
