About Caller Identification
This product is designed to store and display
information about incoming telephone calls. It must
be used 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 product 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 product with Caller ID service,
you can see who’s calling before you answer the
phone. The unit keeps a record of the names and
numbers of the last 70 calls,whether you answer
the phone or not. Each call is numbered in the
call history,with older calls having lower numbers.
When the first call is received,the current time and
date are set automatically (you cannot set them),
and are reset each time a new call comes in.
About Home Area Code and
Local Area Codes
Always program your home area code and,if you
need them,up to four local area codes. Make sure
you read and follow all the directions in “Set Home
Area Code”and “Set Local Area Codes”on pages 7
and 8. Programming these area codes will change
how numbers are displayed in the call history, and
will allow for correct operation of the Display Dial
feature.
