Glossary
Caller ID: Caller identification is a subscriber service available from most local
telephone companies for a fee. When you subscribe to caller identification, you
can see the name and telephone number of the caller before answering the
telephone, if you and the caller are both in areas offering caller ID service with
compatible equipment.
Caller ID with call waiting: This is a single, combined subscriber service which
may be available from your telephone service provider. If you subscribe to
this service, you can use your 993 telephone to see the name and telephone
number of the caller even while on another call (as long as the caller is in
an area with caller ID service and both telephone companies use compatible
equipment).
COVM: Central office voicemail is a subscriber voice message service which
may be available from the telephone service provider. This service may be
called by another name in your area (e.g., call answering or voicemail).
Home area code: This is the area code for your telephone number. Most
users simply dial the seven digits of a telephone number to make a call within
their own area code and  digits outside of their area code. If this applies
to you, enter your own area code into the unit as the home area code. After
programming, if there is a call from within your home area code, the screen
will display the seven digits of the telephone number.
You may, however, live in a region where you are required to dial 0 digits for
calls within your area code (area code and telephone number). If this applies
to you, enter
000 for the home area code and enter your area code as a local
area code. After programming, if there is a call from within your area code,
the screen displays the 0 digits of the telephone number. Be sure to follow
the directions under
Program home and local area codes on page 26 during
feature setup.
Local area code: Most users dial  digits to make calls outside their own
area codes. If this applies to you, you do not need to program any local area
codes.
However, if you dial only 0 digits to make calls to areas outside your
own area code (without dialing ), then program these local area codes
into the telephone. Up to four local area codes can be programmed. After
programming, if there is an incoming call from one of these local area codes,
the screen displays the 0 digits of the telephone number. See
Program
home and local area codes on page 26 for instructions.
Navigation buttons: These are the buttons used when setting up your 993
telephone and for scrolling through the feature options (
ENTER, , , , ).
Primary Line: This is the line on your telephone designated to be selected
automatically when you lift the handset, press
SPEAKER, or press HEADSET.
