Safety in Aircraft
Due to the possible interference caused by this product to an aircraft’s navigation system and its
communications network, using this device’s phone function on board an airplane is against the law in most
countries. If you want to use this device when on board an aircraft, remember to turn off your phone by

Do not use this product in gas stations, fuel depots, chemical plants or where blasting operations are in
progress, or in potentially explosive atmospheres such as fuelling areas, fuel storehouses, below deck on
boats, chemical plants, fuel or chemical transfer or storage facilities, and areas where the air contains
chemicals or particles, such as grain, dust, or metal powders. Please be aware that sparks in such areas
could cause an explosion or fire resulting in bodily injury or even death.
When in any area with a potentially explosive atmosphere or where flammable materials exist, the product
