PIN2
Some functions on the SIM card can be protected by a
secondary code feature.
The PIN2 lock cannot be deactivated. The code can be changed
by a user who knows the old code. Some SIM cards do not have
a PIN2 lock.
Device lock
The device lock protects your P800 and the data in it against
unauthorized use. If the device lock is set to
When SIM changed , it
means that normally the P800 is not locked. However, if the
SIM is changed, the P800 asks you to enter the code to unlock
the P800 before you can use it. Thus, if someone steals your
P800 and puts another SIM card into it, they will not be able to
use it.
The device lock is not on when you buy your P800. You can
change the device lock code to any four to eight digit personal
code.
To activate the device lock
1. Select Phone > Edit > Preferences > Locks
2. Select a lock option.
3. Select Done .
You can choose to have the P800 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 saver device lock to have the device lock activated
when the screen saver goes on.
When using the screen saving device lock, make sure you have
set the device lock to activate at Power on. Otherwise your P800
is unprotected, after Power on, until the screen saver goes on.
Change code
To change a code
1. Select Phone> Edit> Preferences> Locks.
2. Select Change Codes.
3. Select the code you want to change.
4. First enter the old code, then the new one. (To ensure that
you have typed the new code correctly you have to enter it
twice.)
Automatic key lock
This option locks the keys on your P800. This is to protect the
device if the keys are accidentally pressed. When this setting is
active, the flip closed keypad will become automatically locked
after a period of inactivity.
