About Home Area Code and Local Area Codes
Always program your Home Area Code, and, if you need them, up to four
Local Area Codes. (See “Program Home Area Code”on page 7 for
information about the Home Area Code). Programming these area codes
changes how numbers are displayed in the call history, and allows for
correct operation of the Display Dial feature.
Refer to the chart below to determine whether you will need to program
Local Area Codes after you install your phone.
If for You dial Then enter
All calls outside 11 digits No Local Area Codes
your Home Area Code ( 1 + area code
+ phone number)
Some calls outside 10 digits Area codes that do
your Home Area Code (area code not require a “1”
+ phone number)
If you dial 10 digits (area code plus phone number) for calls within
your own area code, include your area code as a Local Area Code.
Use the softkeys to select the area code you want to program
(
LOCAL1–LOCAL4), then use the keypad to enter each area code.
Use the softkey to select DONE.
If you don’t program your Home Area Code, the system will continue
to display the Home Area Code entry screen, and will be unable to display
Caller ID information. If you try to exit area code programming without
entering a Home Area Code, you will hear an error tone.
