Caller ID and CIDCW (Caller ID on Call Waiting)
You must subscribe to Caller ID service through your local telephone provider to use this feature. When the telephone rings, the Caller ID feature allows you to view the caller’s name, phone number, date and time of call. With CIDCW (Caller ID on Call Waiting), you will hear a Call Waiting tone while you are on a call, and the Caller ID data is displayed. To accept the waiting call, press the talk/flash key (see page 18).
Additionally, you can dial a number stored in the Caller ID list or save data to your Memory dial list.
When the Telephone Rings
When the Caller ID message is received, the display shows the caller´s phone number along with the date and time. The incoming call information is stored in the Caller ID record. If the Caller ID service includes the caller´s name, the caller´s name appears on the display (up to 15 letters).
