Caller ID
Caller ID operation
Memory match
If the incoming telephone number exactly matches 
a telephone number in your directory, the name that 
appears on the screen will match the corresponding 
name in your directory. 
For example, if Christine Smith calls, her name will 
appear as Chris if this is how you entered it into your 
directory.
NOTE: The number shown by your caller ID will be in the 
format sent by the phone company. The phone company 
usually delivers ten-digit phone numbers (area code plus 
phone number). If the telephone number of the caller 
does not exactly match a number in your directory, the 
name will appear as it is delivered by the phone company. 
For example, if the phone company includes the area code 
and the directory number does not, the name will appear 
as delivered by the phone company.
