Important safety information

Other medical devices
Operation of any radio transmitting equipment, including PC cards, may interfere
with the functionality of inadequately protected medical devices. Consult a
physician or the manufacturer of the medical device to determine if they are
adequately shielded from external RF energy or if you have any questions. Power
off your PC card in health care facilities when any regulations posted in these
areas instruct you to do so. Hospitals or health care facilities may be using
equipment that could be sensitive to external RF energy.
Vehicles
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.
Posted facilities
Ensure the Nokia D311 PC card is not powered on in any facility where posted
notices so require.
Potentially explosive atmospheres
Power off your PC card when located 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 power off the PC card when at a refuelling point (service
station). Users are reminded of the need to observe restrictions on 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. These include below deck on boats; chemical transfer or storage facilities;
vehicles using liquified 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 normally be advised to turn off your vehicle
engine.
Vehicles
For vehicles equipped with an air bag, remember that an air bag inflates with great
force. Do not place objects in the area over the air bag or in the air bag deployment
area. Serious injury could result if the PC card is improperly placed and the air bag
inflates.
