make sure you do not press any buttons on the key while inside the aircraft
cabin. If you are carrying the key in your bag, etc., ensure th at the buttons are
not likely to be pressed accidentally. Pressing a button may cause the key to

play, airport or other facility that generates strong radio wav es or electrical
noise
● When carrying a portable radio, cellular phone or other wireles s communi-
cation devices
● When multiple wireless keys are in the vicinity
● When the wireless key is in contact with, or is covered by a me tallic object
