Troubleshooting
I hear other calls when
using the telephone.
My caller ID features are
not working properly.
COVM line indicator
remains on.
• 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.
• Make sure you are using the round black cords
that came with the phone. These cords help
prevent crosstalk (hearing other calls).
• 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.
• Make sure the area codes are set correctly
on the telephone (page 42 of the installation
guide).
• Reset the phone. See Common cure for
electronic equipment on the next page.
• Make sure you have reviewed all messages on
that line.
• You might have received a false signal from
the central office. To clear the signal, see
COVM RESET on page 58.
