Caller ID operation

This telephone has a Caller ID feature that works with caller identification

service provided by your local telephone company. There is a fee for this

service, and it may not be available in all areas. This telephone can provide

information only if both you and the caller are in areas offering caller

identification service, and if both telephone companies use compatible

equipment.

When you use this telephone with caller ID service, you can see who's calling

before you answer the call. If you subscribe to caller ID with call waiting, a

combined service available through many local telephone companies, you

can see who's calling even when you are on another call. This service may

be called by different names (such as caller ID with visual call waiting) by

different local telephone companies and may not be available in all areas.

NOTE: You must subscribe to combined caller ID with call waiting as a single

service to see caller ID information for a call waiting call. Check with your tele-

phone company for its availability.

The format of telephone numbers displayed will depend on the home and

local area codes you set (See the AREA CODES section on page 42 of the

installation guide for explanations and setting instructions of area codes):

• If the call came from within your home area code, the screen displays only the

seven-digit number (without an area code).

• If the call came from one of your local area codes, the screen displays 10 digits

(area code plus the seven-digit number).

• If the call did not come from any of the area codes you set.

a. Phone numbers with 10 or more digits will automatically have a 1

inserted and displayed before the number;

b. Phone numbers with fewer than 10 digits will be displayed without a 1.
