About caller ID
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 might 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 answering 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 on another call. This service might be called by 
different names (such as caller ID with visual call waiting) by different local 
telephone companies and might 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 
telephone company for its availability.
The format of telephone numbers displayed depends 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, you see the 
following:
Phone numbers with 10 or more digits automatically have a 1 inserted and 
displayed before the number.
Phone numbers with fewer than 10 digits are displayed without a 1.
