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 phone 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. You should also
consult the manufacturer of any equipment that has
been added to your vehicle.
Posted Facilities
Switch your phone off in any facility where posted
notices require you to do so.
Potentially Explosive Environments
Switch your phone 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 phone 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.
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 areas or
circumstances. Therefore, you should never rely
solely on any wireless phone for essential
communications (medical emergencies, for example).
Before traveling in remote or underdeveloped areas,
plan an alternate method of contacting emergency
services personnel.
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
certain network services and/or phone features are in
use. Check with local service providers.
