by a user who knows the old code.
Device lock
The device lock protects your P910a and the data in it against
unauthorized use.
If the device lock is set to When SIM changed , it means that the
P910a is not normally locked. However, if the SIM has been
changed, the P910a asks you to enter the code to unlock the
P910a before you can use it. This means that if someone steals
your P910a and puts another SIM card into it, they will not be
able to use it.
Note Your operator can block your SIM, if you report that your
phone has been stolen.
The device lock is not on when you buy your P910a. You can
change the device lock code to any four to eight digit personal
code.
The default device lock code is 0000.
To activate the device lock
1. Select Control panel > Device > Locks.
2. Select a lock option.
3. Select
Done .
You can choose to have the P910a locked every time you turn it
on, locked when the SIM card has been changed, or unlocked.
It is also possible to use the device lock in combination with the
screen saver. Just mark the checkbox
Control panel > Device >
Display > Screen > Screen saver device lock to have the device lock
activated when the screen saver goes on.
Note When using the screen saving device lock, make sure you
have set the device lock to activate at Power on. Otherwise your
P910a will be unprotected after Power on, until the screen saver
goes on.
Note You will not be able to browse the contents of your P910a
from a PC, or synchronize items using the SyncStation, when the
P910a device lock is enabled and active.
