When bringing an electronic key onto an aircraft, make sure you do not press any but- tons on the electronic key while inside the ai rcraft cabin. If you are carrying an electronic
key in your bag etc., ensure that the buttons are not likely to be pressed accidentally. Pressing a button may cause the electronic key to emit radio waves that could interferewith the operation of the aircraft.
