designed, or otherwise configured for electromagnetic 
compatibility.

Turn off your mobile device in any facility where posted notices

health care facilities that may be using equipment that is sensitive 
to external RF energy.

Some mobile devices may interfere with some hearing aids. In the 
event of such interference, you may want to consult your hearing 
aid manufacturer or physician to discuss alternatives.

Other Medical Devices

manufacturer of your device to determine if it is adequately 
shielded from RF energy. Your physician may be able to assist you
