Status
).
Note: When calls are barred, calls may be possible to certain emergency numbers in some networks (e.g.
112 or other official emergency number).

Closed user group
: With this network service, you can specify a group of people whom you can call
and who can call you.
Note: When calls are limited to Closed User Groups, calls may be possible to certain emergency numbers
in some networks (e.g. 112 or other official emergency number).
•
Security level
: You can set the phone to ask for the security code when a new SIM card is inserted in
the phone (option
Phone
) or when you select the internal phone book (
Memory
). When you change
this setting, the numbers in Menus 4-1 to 4-3 (Call register) are cleared.
•
Change access codes
: You can change the security code, PIN code, PIN2 code, or barring password.
These codes can include the numbers 0 to 9 only.
Avoid using access codes similar to emergency numbers, such as 112, to prevent accidental dialling of
the emergency number.
