Troubleshooting
I get noise or static when I use the telephone base.
If you subscribe to high-speed Internet service (DSL - digital subscriber
line) through your telephone line, you must install a DSL lter between the
telephone line cord and the telephone wall jack (page 4). The lter prevents
noise and caller ID problems as a result of DSL interference. Please contact
your DSL service provider for more information about DSL lters.
Do not install this phone near a microwave oven or on the same electrical
outlet. You may experience decreased performance while the microwave
oven is operating.
If you plug your phone in with a modem or a surge protector, plug the
phone (or modem/surge protector) into a dierent location. If this does not
solve the problem, relocate your phone or modem farther apart from one
another, or use a dierent surge protector.
If other phones in your home are having the same problem, contact your
telephone service provider (charges may apply).
My caller ID isn’t working.
Caller ID is a subscription service. You must subscribe to this service from
your telephone service provider for this feature to work on your phone.
The call may not be calling from an area that supports caller ID.
Both your and your callers telephone service providers must use caller ID
compatible equipment.
If you subscribe to high-speed Internet service (DSL - digital subscriber
line) through your telephone line, you must install a DSL lter between the
telephone line cord and the telephone wall jack (page 4). The lter prevents
noise and caller ID problems resulting from DSL interference. Please
contact your DSL service provider for more information about DSL lters.
System does not receive caller ID when on a call.
Make sure you subscribe to caller ID with call waiting features from your
telephone service provider. Caller ID features works only if both you and the
caller are in areas oering caller ID service, and if both telephone service
providers use compatible equipment.
Incomplete messages.
If a caller leaves a very long message, part of it may be lost when the system
disconnects the call aer the recordings exceed the maximum recording
time (page 39).
If the caller pauses for longer than three seconds, the system stops
recording and disconnects the call.
