Cause/solution
L You must subscribe to Caller ID service. Contact
your service provider/telephone company for
details.
L If your unit is connected to any additional
telephone equipment such as a Caller ID box or
cordless telephone line jack, plug the unit directly
into the wall jack.
L If you use a DSL/ADSL service, we recommend
connecting a DSL/ADSL filter between the base
unit and the telephone line jack. Contact your
DSL/ADSL provider for details.
L The name display service may not be available in
some areas. Contact your service provider/
telephone company for details.
L Other telephone equipment may be interfering
with this unit. Disconnect the other equipment and
try again.
L Depending on your service provider/telephone
company, the unit may display the caller's
information at the 2nd ring or later.

L The Caller ID number auto edit feature is turned
off. Turn it on and try again (page 21).

activate Caller ID number auto edit.
L The phone number you dialed might have been
edited incorrectly (for example, the long distance
"1" or the area code is missing). Edit the phone
number with another pattern (page 25).
L In order to use Caller ID, call waiting, or Call
Waiting Caller ID (CWID), you must first contact
your service provider/telephone company and
subscribe to the desired service.

subscribed to both Caller ID and Call Waiting with
Caller ID services (CWID).
