Security options (Menu 5)
The purpose of the security system is to prevent
unauthorised use or the altering of important
settings. Activating or changing the security op-
tions requires, in most cases, the appropriate ac-
cess code (see chapter 10 "System: Security" on
page 10-2).
Note: When call barring, fixed dialling, closed
user group, or system lock is in use, calls
may be possible to certain emergency
numbers in some networks (e.g., 112 or
other official emergency number).

Fixed dialling (Menu 5 5)
You may restrict your outgoing calls to a pre-

dialling’ function works only with SIM cards

need not necessarily be assigned numbers

selected group only.
