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 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 air-
craft 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 refuel-
ing points such as near gas pumps at service stations. Observe
restrictions on the use of radio equipment in fuel depots, stor-
age, and distribution areas; chemical plants; or where blasting
operations are in progress. Areas with a potentially explosive
atmospheres are often, but not always, clearly marked. They
include below deck on boats, chemical transfer or storage
facilities, vehicles using liquefied petroleum gas (such as pro-
pane or butane), and areas where the air contains chemicals or
particles such as grain, dust or metal powders.
