4.18 Defining the local area code
The local area code is the prefix without the national or international prefix
("0" or "00", see also 4.16). For Kiel, for example, the local area code is 431.
The prefix must be entered to be able to compare incoming telephone
numbers (always with the prefix) against the telephone book whenever
telephone numbers in your own local area are stored without a prefix.

4.19 Editing the PIN
Before certain procedures, you must enter a 4-digit code number (PIN)
that protects your telephone against unauthorised use/reprogramming. On
delivery, this PIN is set to "0000". Change the PIN to set up effective pro-
tection, but also take a note of your modified PIN because otherwise you
will no longer be able to use some of the functions.
If you have ever forgotten your PIN, it can only be reset by our after-sales
service.
