■ 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. Turn 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.
