Electronic devices
Most modern electronic equipment is shielded from radio frequency (RF)
signals. However, certain electronic equipment may not be shielded against
the RF signals emanating from your wireless phone.
Posted facilities
Switch your phone off in any facility where posted notices so require.
Potentially explosive atmospheres
Switch off your phone when in any area with a potentially explosive
atmosphere and obey all signs and instructions. Sparks in such areas could
cause an explosion or fire resulting in bodily injury or even death.
Users are advised to switch off the phone when at a refuelling point (service
station). Users are reminded of the need to observe restrictions regarding
the use of radio equipment in fuel depots (fuel 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/
storage facilities, vehicles using liquefied petroleum gas (such as propane
or butane), areas where the air contains chemicals or particles, such as
grain, dust or metal powders, and any other area where you would be
advised to turn off your vehicle engine.
Vehicles
Only qualified personnel should install or service the phone in a vehicle.
Faulty installation or service may be dangerous and invalidate the warranty.
RF signals may affect improperly installed or inadequately shielded electronic
systems in motor vehicles (for example, electronic fuel injection systems,
electronic anti-skid (anti-lock) braking systems, electronic speed control
systems, air bag systems).
Check with the manufacturer or its representative regarding your vehicle.
You should also consult the manufacturer of any equipment that has been
added to your vehicle.
