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.
