Cause/solution
L You must subscribe to a Caller ID service.
Contact your service provider/telephone
company for details.
L If your unit is connected to any additional
telephone equipment, remove and 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 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 Move closer to the base unit.
L Incorrect time information from incoming
Caller ID changes the time. Set the time
adjustment to "Manual" (off) (page 21).
