You can protect your phone against unauthorised use with the
security code (security code). To do this, you need to set the menu
function Security level (4-5-5) to Phone or Memory.
• When set to Phone, the phone will ask for the security code
whenever a new SIM card is inserted into the phone. When set
to Memory, the security code is required to enter the phone’s
internal phone book.
The security code is also required for using some functions, for
example, to clear a the phone book or to restore the factory settings.
The security code is usually supplied with the phone (on an
identification sticker). If not, contact your local dealer.
The factory setting for the security code is 12345. Change the code
within the menu 4-5-6 Change of access codes. Keep the
new code secret and in a safe place which is separate from the
phone.
Note: If you enter an incorrect security code five times in
succession, the phone is blocked and will not accept the
correct security code for the next five minutes.
Tip: You can also restrict calls made from or to your phone if
supported by your network. See also Call barring
service (4-5-2), Fixed dialling (4-5-3) and
Closed user group (4-5-4) in the Settings chapter.
