Problem Cause/solution
Caller information is not displayed. RYou must subscribe to Caller ID service. Contact your
service provider/telephone company for details.
RIf your unit is connected to any additional telephone
equipment such as a Caller ID box or cordless telephone

RIf 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.

areas. Contact your service provider/telephone company for
details.
