Menu functions

• 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.
Restore factory settings (Menu 6-4)
You can reset the menu settings to their original values. This function has no effect, for example, on
the names and phone numbers in the phone book. Also, your FM radio and Music player settings should
not be affected.
■ Call divert (Menu 7)
You can direct your incoming calls to your voice mailbox or some other phone
number (network service).
To access this menu: In standby mode, press ( Menu ), scroll to Call divert , and press ( Select ).
1. Scroll with or to the desired divert option, and press ( Select ). For example, select
Divert when busy to divert calls when you are in a call or when you want to reject a call.
