Additional safety information
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 contains chemicals or particles such as
grain, dust, or metal powders. You should check with the manufacturers of
vehicles using liquefied petroleum gas (such as propane or butane) to determine
if this device can be safely used in their vicinity.
