Device lock
The device lock protects your P900 and the data in it against
unauthorized use.
If the device lock is set to
When SIM changed
, it means that the
P900 is not normally locked. However, if the SIM has been
changed, the P900 asks you to enter the code to unlock the P900
before you can use it. This means that if someone steals your
P900 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 P900. 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

.
You can choose to have the P900 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
P900 will be unprotected after Power on, until the screen saver
goes on.
