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.
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 like medical emergencies.
To make or receive 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 certain network services and/
or phone features are in use. Check with local service
providers.
To make an emergency call:
1. Switch on the phone.
2. Key in the emergency number for your present
location. Emergency numbers vary by location.
3. Press [ ].
