Problem Suggestion
I hear other calls when
using the telephone.
Disconnect the telephone base from the telephone jack. Plug in a different telephone. If you
still hear other calls, the problem is probably in the wiring or local service. Call your local
telephone company.
I hear noise in the
cordless handset, and
none of the keys or
buttons work.
Make sure the telephone line cord is plugged in securely.
My caller ID features are
not working properly.
Caller ID is a subscription service. You must subscribe to this service from your local telephone
company for this feature to work on your telephone.
The caller may not be calling from an area which supports caller ID.
Both you and the caller’s telephone companies must use equipment which are compatible
with caller ID service.
If you subscribe to DSL service, install a DSL lter to the telephone line between the telephone
base and the telephone line jack. Contact your DSL service provider for lter information.
The system does not
receive caller ID or
the system does not
display caller ID during
call waiting.
Make sure you subscribe to Caller ID with Call Waiting features services provided by the local
telephone company.
