Troubleshooting
Problem Suggestion
I hear other calls when
using the telephone.
Disconnect the telephone base from the telephone jack. Plug in a different telephone. If
there are still other calls, the problem is probably in the wiring or local service. Call your local
telephone company.
Press CHAN/REMOVE to switch to a clearer channel when on a call.
I hear noise in the
handset, and none of
the keys or buttons
work.
Make sure the telephone line cord is plugged in securely.
Remove and re-insert the battery.
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 high-speed Internet service (Digital Subscriber Line - DSL) through your
telephone lines, you must install a DSL lter between the telephone base and the telephone
wall jack. The lter will prevent noise and caller ID problems caused by DSL interference.
Please contact your DSL service provider for more information about DSL lters.
