Security in both directions
You can prevent the misuse of your telephone by others by means of various
security functions. You can protect your telephone’s settings by means of a code
(telephone PIN).
Change telephone PIN (personal identification number)
You can protect the settings programmed at your telephone against unautho-
rised or unintended changes by assigning a PIN. In the factory pre-set, the PIN
(personal identification number) is "0000".
Press the R-key and the redial key at the same time. (The
„P“ for „Programming-mode“ appears in the display.)
Select the function „Change PIN“ using the arrow keys and
confirm with the
key.
Enter 4-digit PIN.
Enter new 4-digit-PIN two time one after the other and
confirm with the
key.
Select another function using the arrow keys or exit the
programming menu with the C-key.
Causion:
If you change the PIN, please make sure that you do not forget
this code as it is used as an "access key" to the programming level
of your telephone. Should you have forgotten your PIN, it can only
be reset to the factory pre-set by the manufacturer. Ask your dealer.
Dialling restrictions
At your telephone, you can set two different types of dialling restrictions:
a)
Number restriction
: The dialling procedure is restricted for individual
telephone numbers (e. g. a specific prefix number). You have to enter
restricted numbers to use this function.
