Chapter 10 - System
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
at the beginning of this "Security" section.
The new code must be 5 digits long. The Lock
code can also be changed in the phone inter-
face Security options menu (Menu 5 6 1).
The lock code is needed to lock (except when
the autolock period is in use) and unlock the
communicator. The device can be locked in
both the communicator interface (System,
Security: Lock system) and the phone inter-
face (System Lock, Menu 5 8). The lock code is
also required when you change the SIM
change security setting and turn the Autolock
period on or off. You can find the lock code on
a sticker in the sales package of your commu-
nicator. Keep it secret and in a safe place,
separate from the communicator.
If you key in an incorrect lock code (you get a
code error message) several times in succes-
sion, the communicator must be sent back to
the dealer to unlock the device.
Barring password
When the phone interface is switched on, this
setting allows you to change the barring
password. The new code must be 4 digits long.
The Barring password can also be changed in
the phone interface Security options menu
(Menu 5 6 4).
The barring password is needed to change call
barrings, see chapter 4 "Telephone: Telephone
settings". You obtain the password from your
network operator when you subscribe to the
service.
If the password is changed correctly, the
communicator requests the network to per-
form the desired operation (see chapter 4
"Telephone: Telephone settings - Changing
the settings of network services").
Booking password
You can give your calendar booking password
to those whom you allow to send event reser-
vations to your own Calendar. The maximum
length of the booking password is 8 charac-
ters, and it may contain letters, numbers,
spaces, "-" and "_". See chapter 9 "Calendar:
Calendar booking".
