Always switch off your phone:
Before boarding an aircraft and or when packing the
phone in your luggage.
In hospitals, clinics, other health care centres and anywhere
else where you may be in the close vicinity of medical
equipment.
If you are a user of a pacemaker or hearing aid, or expect to
use your cellular phone in the immediate vicinity of
someone who does, then take the following precautionary
steps:
• Consult your physician and pacemaker or hearing aid manufacturer to
learn whether your particular device is susceptible to cellular phone
interference.
• Carry and hold your cellular phone at safe distance from the implanted
pacemaker device and electrode (20 centimetres is generally accepted as
a "safe distance", however it is advisable to check with your physician and
pacemaker manufacturer).
Always switch off your phone
and do not remove the battery in:
• Areas with a potentially explosive atmosphere (e.g. petrol
stations and also areas where the air contains dust
particles, such as metal powders).
• A vehicle transporting flammable products (even if the
vehicle is parked) or a vehicle powered by liquefied
petroleum gas (LPG), check first that the vehicle complies
with the applicable safety rules.
• Areas where you are requested to turn off radio
transmitting devices, such as quarries or other areas
where blasting operations are in progress.
