Menu 5 2, Security Level
The three levels of security are None, Memory and Phone.
The following table summarizes the security levels.
The phone keeps a list of up to five different SIM cards
used with the phone. When the phone asks for a
security code and you enter the correct code, the SIM
card is added to the phone's SIM card list and the SIM
card becomes an 'Owner's card'. The phone also
memorizes which memory - A or B - is selected for use.
Regardless of the selected security level, all temporarily
stored phone numbers are erased when a new SIM
card is installed. On the other hand, these phone
numbers are not erased when a previously used SIM
card is inserted, regardless of the selected security level.
Note: Whenever you change the security level, all
temporarily stored phone numbers are erased.
