Hearing aids:
Some digital wireless phones may
interfere with some hearing aids. In the

to consult your network operator.
Other medical devices:
Operation of any radio transmitting
equipment, including cellular phones, may
interfere with the functionality 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.
