Requirements
When in a hospital or other health care facility, observe the restrictions about the use of
mobiles. Switch the cellular terminal or mobile off, medical equipment may be sensitive and
not operate normally due to RF energy interference.
Switch off the cellular terminal or mobile before boarding an aircraft. Make sure it is switched
off. The operation of wireless appliances in an aircraft is forbidden to prevent interference with
communication systems. Forgetting to think much of these instructions may impact the flight
safety, or offend local legal action, or both.
Do not operate the cellular terminal or mobile in the presence of flammable gases or fumes.
Switch off the cellular terminal when you are near petrol stations, fuel depots, chemical plants
or where blasting operations are in progress. Operation of any electrical equipment in
potentially explosive atmospheres can constitute a safety hazard.
Your cellular terminal or mobile receives and transmits radio frequency energy while switched
on. RF interference can occur if it is used close to TV sets, radios, computers or other electric
equipment.
Road safety comes first! Do not use a hand-held cellular terminal or mobile when driving a
vehicle, unless it is securely mounted in a holder for hands free operation. Before making a
call with a hand-held terminal or mobile, park the vehicle.
Mobiles operate over radio frequency signals and cellular networks and cannot be guaranteed
to connect in all conditions, especially with a mobile fee or an invalid SIM card. While you are
in this condition and need emergent help, please remember to use emergency calls. In order
to make or receive calls, the cellular terminal or mobile must be switched on and in a service
area with adequate cellular signal strength.
Some networks do not allow for emergency call if certain network services or phone features
are in use (e.g. lock functions, fixed dialing etc.). You may have to deactivate those features
before you can make an emergency call.
Also, some networks require that a valid SIM card be properly inserted in the cellular terminal
or mobile.
