Note: When security features that restrict calls are in use (call barring, closed user group and fixed dialling), calls may be possible to certain emergency numbers in some networks (e.g. 112, 911 or other official emergency numbers).

Press Menu and select Settings > Security settings. Select

• PIN code request to set the phone to ask for your PIN code every time the phone is switched on. Some SIM cards do not allow turning this function off.
• Call barring service (network service) to restrict incoming calls to and outgoing calls from your phone.
• Fixed dialling to restrict your outgoing calls to selected phone numbers if this function is supported by your SIM card.
• Closed user group. With this network service you can specify a group of people whom you can call and who can call you.
• Security level. The preset security code is 12345. Select Phone to set the phone to ask for the security code when a new SIM card is inserted. Select Memory and the phone will ask for the security code when the SIM card’s memory is selected and you want to change the memory in use.
• Access codes to change the security code, PIN code, PIN2 code or barring password.
