● 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.
Using your device while flying in aircraft is prohibited. Switch off your device before
boarding an aircraft. The use of wireless teledevices in an aircraft may be dangerous to
the operation of the aircraft, disrupt the wireless telephone network, and may be illegal.
Potentially explosive environments
Switch off your device when in any area with a potentially explosive atmosphere, and
obey all signs and instructions. Potentially explosive atmospheres include areas where
you would normally be advised to turn off your vehicle engine. Sparks in such areas
could cause an explosion or fire resulting in bodily injury or even death. Switch off the
device at refuelling points such as near gas pumps at service stations. Observe
restrictions on the use of radio equipment in fuel depots, storage, and distribution
areas; chemical plants; or where blasting operations are in progress. Areas with a
potentially explosive atmosphere are often, but not always, clearly marked. They include
below deck on boats, chemical transfer or storage facilities and areas where the air
