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.
