Cause/solution
R Make sure that you have long distance service.
Cause/solution
R You must subscribe to Call Display service.
Contact your service provider/telephone company
for details.
R If your unit is connected to any additional
telephone equipment such as a Call Display box
or cordless telephone line jack, plug the unit
directly into the wall jack.
R 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.
R The name display service may not be available in
some areas. Contact your service provider/
telephone company for details.
R Other telephone equipment may be interfering
with this unit. Disconnect the other equipment and
try again.
R Depending on your service provider/telephone
company, the unit may display or announce the
caller's information at the 2nd ring or later.
R Move closer to the base unit.
R The handset or base unit's ringer volume is turned
off. Adjust it (page 15, 25).
R The Talking Call Display feature is turned off. Turn
it on (page 25).
R The number of rings for the answering system is
set to "2 rings" or "Toll saver". Select a
different setting (page 39).
R If the base unit and another handset are having
an intercom call, your handset does not announce
caller information.
R 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 34).
R Incorrect time information from incoming Call
Display changes the time. Set the time adjustment
to "Manual" (off) (page 25).
