Assigning an MSN
Your telephone can manage up to 5 Multiple Subscriber Numbers (MSN). You must have
at least one MSN programmed in order to use your telephone.
1. Press the softkey under MENU . Press to scroll to
SETTINGS
and press OK to confirm.
2. Select the relevant MSN in the menu MSN SETTINGS . Program the MSNs and associated
user names, and activate/deactivate the functions “Anonymous call” and “Call waiting”.
If you are already on the telephone, the “Call waiting” function emits an acoustic signal
to alert you to an incoming call.
Note • You can also use the installation assistant to set up your MSNs and define
the associated settings.
• The MSNs must be programmed without a prefix (e.g. 031).
