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 regulations
posted in these areas instruct you
to do so.
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
environments
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 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. They include
the areas below decks 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.
