Appendix
If your telephone is plugged in with a modem or a surge protector, plug the
telephone (or modem/surge protector) into a different location. If this doesn’t
solve the problem, relocate your telephone or modem farther apart from each
other, or use a different surge protector.
The location of your telephone base can impact the performance of your cordless
phone. For better reception, install the telephone base in a centralized location
within your home or office, away from walls or other obstructions. In many
environments, elevating the telephone base improves overall performance.
Disconnect the telephone base from the telephone wall jack and plug in a corded
telephone. If calls are still not clear, the problem is probably in the wiring or
telephone service. Contact your telephone service provider (charges may apply).
If other telephones in your home are having the same problem, the problem is in
the wiring or telephone service. Contact your telephone service provider (charges
may apply).
I hear other calls when using the telephone.
Disconnect the telephone base from the telephone wall jack. Plug in a different
telephone. If you still hear other calls, the problem is probably in the wiring or
telephone service. Contact your telephone service provider.
I hear noise on the cordless handset and the keys do not work.
Make sure the telephone line cord is plugged in securely.
The caller ID features are not working properly.
Caller ID is a subscription service. You must subscribe to this service from your
telephone service provider for this feature to work on your telephone.
The caller may not be calling from an area which supports caller ID.
Both your and the caller’s telephone service providers must use equipment
compatible with the caller ID service.
The caller ID information displays after the first or second ring.
If you subscribe to high-speed Internet service (DSL - digital subscriber line)
through your telephone line, you must install a DSL filter between the telephone
line cord and the telephone wall jack. The filter prevents noise and caller ID
problems caused by DSL interference. Contact your DSL service provider for
more information about DSL filters.
The telephone does not receive caller ID or the telephone does not
show caller ID during call waiting.
Make sure you subscribe to caller ID with call waiting features provided by your
telephone service provider.
