Troubleshooting
Other electronic products can cause interference
to your telephone. Try installing your telephone as
far away as possible from the following electronic
devices: wireless routers, radios, radio towers, pager
towers, cellular telephones, digital telephones, room
monitors, televisions, VCRs, personal computers,
kitchen appliances, wireless routers, and other cordless
telephones.
If you have a headset plugged into the telephone, try
unplugging it and firmly plugging it in again.
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 solves the
problem, relocate your telephone or modem farther
apart from each other, or use a different surge
protector.
Disconnect the telephone base from the modular jack
and plug in another corded telephone. If calls are still
not clear, the problem is probably in the wiring or local
service. Contact your local service company (charges
may apply).
Do you have DSL service? If yes, you need to have a
DSL filter installed. Contact your DSL service provider
for a DSL filter.
My calls fade out
or cut in and out
when I am using
the telephone.
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.
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, you need to have a DSL
filter installed. Contact your DSL service provider for a
DSL filter.
My caller ID
features are not
working properly.
