Home area code: This is the area code for your telephone number. Users
simply dial the seven digits of a telephone number to make a call within their
own area code and 11 digits outside of their area code. If this applies to you,
you should enter your own area code into the telephone as the home area
code. After setting, if you receive a call from within your home area code, the
screen displays the last seven digits of the telephone number.
You might, 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-
telephone system.
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 (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.
Mailbox: A place to store answering system messages. The 1080 phone can
have separate mailboxes for private messages, central messages, and system
extension messages.
Memory loss protection: Even if the telephone has no AC power or battery,
all programming and messages are retained.
Navigation keys: These are the buttons you use to program your 1080 phone
and for scrolling through feature options ([ENTER], [ ], [ ], [ ], [ ]).
Prime line: This is the line on the telephone you assign to be selected
automatically when you lift the handset, press [ SPEAKER] or press
[HEADSET] to answer or make a call.
