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 your mobile device off 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 before using
your mobile device in a motor vehicle. You should
also consult the manufacturer of any equipment that
has been added to your vehicle.
Posted Facilities
Switch your mobile device off in any facility where
posted notices require you to do so.
Potentially Explosive Environments
Switch your mobile device off 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 the mobile device
off 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.
