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 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 accessories. 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 in any area with a potentially explosive atmosphere. Obey all posted instructions. Sparks in such
areas could cause an explosion or fire resulting in bodily injury or death. Switch off the device at refuelling points such
as near gas pumps at service stations. Observe restrictions 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 areas where you would be advised to turn off your vehicle engine, below deck on boats,
chemical transfer or storage facilities and 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.
