not press any buttons on the elec-
tronic key while inside the aircraft
cabin. If you are carrying an elec-
tronic key in your bag, etc., ensure
that the buttons are not likely to be
pressed accidentally. Pressing a
button may cause the electronic key

fere with the oper ation of the air-
craft.
■Electronic key battery depletion
●The standard battery life is 1 to 2
years.
●If the battery becomes low, an
alarm will sound in the cabin when

●To reduce key battery depletion when the electronic key is to not
be used for long periods of time,
set the electronic key to the bat-
tery-saving mode. (
P.133)
●As the electronic key always
receives radio waves, the battery
will become depleted even if the
electronic key is not used. The fol-
lowing symptoms indicate that the
electronic key battery may be
depleted. Replace the battery
when necessary.
• The smart key system or the wire- less remote contro l does not oper-
ate.

cal appliances that produce a
magnetic field:
•TVs
• Personal computers
• Cellular phones, cordless phones and battery chargers
• Recharging cellular phones or cordless phones

out, resulting in death or serious
injury.
●Ensure that all doors are prop-
erly closed and locked.

■When opening or closing a
door

open and whether a strong wind
is blowing. When opening or clos-
ing the door, hold the door handle
tightly to prepare for any unpre-
dictable movement.
