Activating the Screen
Lock
When you activate the screen lock, you can lock access
to normal phone functions and to applications. This
feature is useful for preventing unwanted use of the unit
while you are away from your seat.
Phone numbers set beforehand as emergency
numbers can still be dialed, and calls can still be
received.
Notice
•If an unlock pattern, PIN, or password has not
been set, the screen lock cannot be activated,
so be sure to set one beforehand (Page 111).
1. Tap [Screen lock now] in the application dock.
•The screen lock will be activated and the screen
saver will start.
Note
•To dial an emergency number, see page 49.
Unlocking the Screen Lock
1. Touch the display or key sheet, or press an
alphanumeric or symbol key on an attached USB
keyboard.
Or, lift the handset off its cradle.
2. Trace the unlock pattern, enter the PIN, or enter the
password.
Note
•The lock is activated according to the method
you selected for [Set up screen lock] in the
[Security] settings (Page 111).
•If you selected [Pattern] in the lock settings,
trace the unlock pattern in a single stroke
without lifting your finger off the display.
•If the unlock pattern, PIN, or password is input
incorrectly 5 times in a row, a message will be
displayed, and you will not be able to unlock the
unit for 30 seconds.
