■When riding in an aircraft
When bringing an electronic key onto an aircraft, make sure you do not press
any buttons on the electronic key while inside the aircraft 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 interfere with the operation of the aircraft.

cate that the electronic key battery may be depleted. Replace the battery
when necessary. ( →P. 360)
