Pressing Close will close the security settings
view and return to the Security main view.
The security settings list is as follows:
PIN code request — On / Off (default)
If you set the PIN (Personal Identity Number)
code request on, the system requests the code
every time when the phone interface is turned
on by pressing . You can also turn the PIN
code request on or off in the phone interface
Security options menu (Menu 5 1). This set-
ting cannot be changed if the phone interface
is switched off.
Note: Some SIM cards do not allow you to turn
the PIN code request off.
If you enter the PIN code incorrectly three
times in a row, you will need a PUK code to
unblock the SIM card. When the SIM card is
blocked, you cannot make or receive any calls
(including faxes, short messages, mail, etc.),
except emergency calls. Otherwise, the com-
municator can be used normally.
Autolock period — Autolock off (default) / 1 / 2 / 5
/ 10 / 15 minutes
This setting determines the security time-out
period, after which the system will lock. The
timer is reset by any input, calls or data trans-
fer/printing activity.
SIM change security — On (default) / Off
When active, this security option checks
whether the SIM card in the communicator
has been changed. The check is made every
time the phone interface is switched on. The
SIM change security option can also be acti-
vated in the phone interface Security options
menu (Menu 5 2).
If the SIM card has been changed and the
new SIM card has not previously been used
with your communicator, the communicator
locks itself until the lock code, supplied with
the phone, is correctly entered. The communi-
cator recognises five different SIM cards as
the owner’s cards.
PIN code
When the phone interface is switched on, this
setting allows you to change the PIN code.
The changing procedure is as described at the
beginning of this "Security" section. The new
PIN code must be 4 to 8 digits long. The PIN
code can also be changed in the phone inter-
face Security options menu (Menu 5 6 2).
The PIN code is supplied with the SIM card.
When the PIN code request is enabled, the
code is required each time the phone inter-
face is switched on. The PIN code request
must be turned on to change the code.
If you enter a wrong PIN code three times in
succession, the PIN code is disabled and can-
not be used any more. At the prompt, key in
the PUK code (see below) and follow the in-
structions on the display.
Lock code
This setting allows you to change the lock
code. The changing procedure is as described

The new code must be 5 digits long. The lock
code can also be changed in the phone inter-
