ENTERING YOUR AREA CODE  
If you enter a 3-digit area code number in  
the Area Code” option, your local area  
code does not appear in Caller ID messages.  
For calls received from outside your local  
area code, you will see a full 10-digit  
number.  
AREA CODE allows you to enter your local  
area code so CID will not show the area  
code from local callers. See the next page  
for area code instructions.
