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 minimise the potential
for interference.
• Turn the wireless device off immediately if there is any reason to suspect that
interference is taking place.

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. Do not store or carry flammable liquids, gases, or explosive materials in the same
compartment as the device, its parts, or enhancements.
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 contains chemicals or particles such as grain, dust, or metal
powders. You should check with the manufacturers of vehicles using liquefied petroleum gas
