You may, however, live in a region where you must dial 10 digits (area code
and telephone number) for calls within your own area code. If this applies to
you, enter 000 for the home area code and enter your area code as a local
area code. After setting, if you receive a call from within your area code, the
screen displays the 10 digits of the telephone number.
For details, see the AREA CODES section (page 42 of the installation guide).
Line group: A group of system telephones sharing some lines within a multi-

Local area code: Most users dial 11 digits to make calls outside their home
area codes. If this applies to you, you 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 set these local area codes on the
telephone. Up to five local area codes can be set. For details, see the AREA
CODES section on page 42 of the installation guide. After setting, if you
receive a call from one of these local area codes, the screen displays the 10
digits of the telephone number.
