SECURITY LEVEL (Menu 5 2)
The phone is provided with a security system which allows
you to prevent unauthorised use of the phone. The system is
based on three levels of security: None, Memory and Phone.
The selected level determines whether the security code,
supplied with the phone, is required to start up the phone
and to access certain memory functions, such as selecting
the phone memory (memory B).
The phone keeps a list of the SIM cards which are used with
the phone. This list may contain the information on up to five
different SIM cards.
When the phone asks for a security code and you enter the
correct code, the SIM card’s information is added to the SIM
card list and the SIM card becomes an ‘owner’s card’. Be-
sides this information, the phone also memorises which
memory - SIM card or phone memory - is selected for use.
Regardless of the selected security level, all temporarily
stored phone numbers are erased when a new SIM card is in-
stalled. On the other hand, these phone numbers are not
erased when a previously used SIM card is inserted, regard-
less of the selected security level.
Note: Whenever you change the security level, all temporarily
stored phone numbers will be erased.
