RF energy or if you have any questions. Switch off your device 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.
Implanted medical devices
Manufacturers of medical devices recommend that a minimum separation of 15.3 centimeters
(6 inches) should be maintained 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 inches) from the medical
device when the wireless device is turned on.
• Not carry the wireless device in a breast pocket.
• Hold the wireless device to the ear opposite the medical device to minimize the potential
for interference.
• Turn the wireless device off immediately if there is any reason to suspect that
interference is taking place.
• Read and follow the directions from the manufacturer of their 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. If interference occurs,
consult your service provider.

Vehicles
RF signals may affect improperly installed or inadequately shielded electronic systems in
motor vehicles such as electronic fuel injection systems, electronic antiskid (antilock)
braking systems, electronic speed control systems, and air bag systems. For more information,
check with the manufacturer, or its representative, of your vehicle or any equipment that
has been added.
Only qualified personnel should service the device or install the device in a vehicle. Faulty
installation or service may be dangerous and may invalidate any warranty that may apply to
the device. Check regularly that all wireless device equipment in your vehicle is mounted and
operating properly. Do not store or carry flammable liquids, gases, or explosive materials in
the same compartment as the device, its parts, or enhancements. For vehicles equipped with
an air bag, remember that air bags inflate with great force. Do not place objects, including
installed or portable wireless equipment in the area over the air bag or in the air bag deployment
area. If in-vehicle wireless equipment is improperly installed and the air bag inflates, serious
injury could result.
