Extra features
Adding extra security
The cordless telephone system has the unique advantages of 
DECT (Digital Enhanced Cordless Telecommunications); 
this means that no one can eavesdrop on your calls. In 
addition, you can also protect the cordless telephone system 
by changing the default security codes.
There are three codes for the security of the cordless 
telephone system:
Home base station Personal Identification 
Number (PIN) code: this code must be entered 
before the home base station settings can be 
changed.
Cordless phone PIN code: using this PIN code, 
you can protect the cordless phone against use 
and/or programming by other people.
Authentication Code (AC): this is a secret code of 
the home base station which is necessary to 
subscribe an extra cordless phone to the home 
base station.
Changing the home base station 
PIN code
To prevent unauthorized people accessing the settings of the 
home base station it is secured by a PIN code. Each time you 
want to change the settings of the home base station you must 
enter the PIN code. You cannot switch off this security feature 
but you can change the PIN code on the home base station. 
You change the settings on the home base station using a 
cordless phone connected to this base station.
When entering the PIN code you enter the unique 
combination of numbers using the numeric keys on 
the cordless phone, within the range of the home base 
station. The default home base station PIN code is 
1111.
Do not forget the PIN code of the home base station! 
If you do, ask your dealer to reset the default PIN 
code.
To change the PIN code of the home base station:
1. Press   and then press the R key for 2 seconds.
Four dashes are displayed.
