Safety warnings and instructions

Road safety comes first

Do not use a hand-held phone while driving. Use hands-free
fittings when calls are unavoidable while driving. In some
countries, dialing or receiving calls while driving is illegal!

Switch off in aircraft

Wireless devices can cause interference in aircraft. Using a
mobile phone during flight is illegal and risky.
Please make sure that your mobile phone is powered off in

flight.

Switch off before entering risky areas

Strictly observe the relevant laws, codes, and regulations on
the use of mobile phones in risky areas. Turn off your mobile
phone before entering a place susceptible to explosion, such
as an oil station, oil tank, chemical plant or a place where a
blasting process is under way.
Follow any special regulations at any area such as hospitals
and always switch off your phone whenever it is forbidden to
use it or, when it may cause interference or danger. Properly
use your mobile phone near medical equipment, such as
pacemakers, hearing aids and some other electronic medical
devices, as it may cause interference.
