CALLER ID OPERATION

Display Dial

NOTE: You must have a phone attached to the unit (see INSTALLATION) and you must lift the receiver for this feature to work.

As you review calls in call history, you can dial a displayed phone number. If the call information came from your Home Area Code (the one you programmed during Installation), the screen displays only the seven-digit number you are calling (without an area code). When you use Display Dial, the system dials the seven displayed digits. If the call information came from outside your Home Area Code, the screen displays the seven- digit number plus the area code. When you use Display Dial, the system dials the 10 displayed digits, plus the digit “1” when appropriate. (See “Home Area Code and Local Area Code Guidelines” in SET UP SYSTEM FEATURES.)
