Changing home base station
authentication code
The home base station can handle up to 8 cordless phones.
An authentication code makes sure that only the cordless
phones you want can use the home base station. This code is
a secret number of between 4 and 8 digits. Only cordless
phones that have been subscribed can connect to the home base
station.
To subscribe a cordless phone to the home base station
you need:
• The authentication code.
• The PARK code (on the home base station).
• To press the Search/Subscribe button.
The default authentication code is preset to
12345678. We recommend that you change this code
directly after installing the cordless telephone system.
Do not forget the authentication code!
You can reset the authentication code to its default
value (12345678) by clearing all home base station
settings. How to proceed is described in “Clearing all
home base station settings” under “Settings”.
