Home Area Code Guidelines

Most users simply dial the seven digits of a phone number to make a call within their Home Area Code and 11 digits outside of their Home Area Code. If this applies to you, you should program your Home Area Code into the unit. After programming, if you receive a call from within your Home Area Code, the screen will display the seven digits of the phone number. When you use Display Dial, the unit will know to ignore the Home Area Code, and dial only the seven digits of the phone number.

You may, however, live in a region where for calls within your Home Area Code you must dial 10 digits (that is, the three-digit area code and the seven digits of the phone number) or even 11 digits (the digit “1” plus the area code and phone number). If you must dial 10 digits for calls within your Home Area Code, you should program “000”as your Home Area Code into the unit, and program your Home Area Code as a Local Area Code (see Local Area Code guidelines). After programming, if you receive a call from within your Home Area Code, the screen displays the 10 digits of the phone number. When you use Display Dial, the unit will know to dial your Home Area Code along with the seven digits of the telephone number.

If you must dial “1” for calls within your Home Area Code, you should program “000” instead of your Home Area Code into the unit (and do not program your Home Area Code as a Local Area Code). After programming, if you receive a call from within your Home Area Code, the screen displays the 10 digits of the phone number. When you use Display Dial, the unit will know to dial the digit “1”, along with your Home Area Code and the seven digits of the telephone number.

Local Area Code Guidelines

Most users dial 11 digits to make calls outside their Home Area Code. These users do not need to program any Local Area Codes.

However, if you dial only 10 digits to make calls to some areas outside your Home Area Code (without dialing “1”), then program these Local Area Codes into the unit (up to four codes can be programmed). After programming, if you receive a call from one of these Local Area Codes, the screen displays the 10 digits of the phone number. When you use Display Dial, the unit will know to dial the 10 digits without inserting a “1”before the area code.
