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.
Emergency calls
This phone, like any wireless phone, operates using
radio signals, wireless and landline networks, as
well as user-programmed functions, which cannot
guarantee connection in all conditions. Therefore,
you should never rely solely on any wireless phone
for essential communications (medical
emergencies, for example).
Remember, to make or receive any calls the phone
must be switched on and in a service area with
adequate signal strength. Emergency calls may not
be possible on all wireless phone networks or when
