*Hearing Aids
Some digital wireless phones may interfere with some hearing aids. In the event of such
interference, you may wish to consult your hearing aid manufacturer to discuss
alternatives.
*Other Medical Devices
If you use any other personal medical devices, consult the manufacturer of your device
to determine
if it is adequately shielded from external RF energy. Your physician may be able to assist
you in obtaining this information. Switch off your phone 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. 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
Switch off your phone in any facility where posted notices require you to do so.
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 while at a refueling 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.
They include below deck on boats, chemical transfer or 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 normally be advised to turn off your vehicle engine.
