adequately shielded from external RF energy. Switch off your device when
regulations posted instruct you to do so. Hospitals or health care facilities may use
equipment sensitive to external RF energy.
Implanted medical devices
Manufacturers of medical devices recommend a minimum separation of 15.3
centimeters (6 inches) between a wireless device and an implanted medical device,
such as a pacemaker or implanted cardioverter defibrillator, to avoid potential
interference with the medical device. Persons who have such devices should:
• Always keep the wireless device more than 15.3 centimeters (6 inch) from the
medical device.
• Not carry the wireless device in a breast pocket.
• Hold the wireless device to the ear opposite the medical device.
• Turn the wireless device off if there is any reason to suspect that interference is
taking place.
• Follow the manufactures directions for the implanted medical device.
If you have any questions about using your wireless device with an implanted
medical device, consult your health care provider.
Hearing aids
Some digital wireless devices may interfere with some hearing aids.
■ Vehicles
RF signals may affect improperly installed or inadequately shielded electronic
systems in motor vehicles such as electronic fuel injection, electronic antilock
braking, electronic speed control, and air bag systems. For more information, check
with the manufacturer of your vehicle or its equipment.
