1.3. Usage limitations
It is essential to turn off the smartphone in
the following situations:
• Before boarding an aircraft or before
packing it in your luggage. The use of
radio devices in aircraft can have
dangerous effects on the flight controls
and interrupt radio contact and is thus
prohibited.
• In hospitals, clinics or other health
centres and in any locations in the direct
vicinity of medical devices.
• In all locations where there is a risk of
explosion (e.g. petrol stations; in
dust-filled environments, e.g. where
there is metal dust).
• In locations where the use of radio-
controlled devices is prohibited, e.g. on
construction sites or locations where
people are working with explosives.
• While driving a motor vehicle (if no
hands-free car kit is available).
