1.3. Usage limitations
It is essential to turn off the telephone 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).
