Troubleshooting
The telephone does not ring when there is an incoming call.
Make sure the ringer is on (see page 16).
Make sure the telephone line cord is plugged in properly (see Telephone
installation on page 6).
There may be too many extension telephones on the telephone line to allow
all of them to ring simultaneously. Try unplugging one telephone at a time
until the telephones start ringing.
Test a working telephone at the same telephone jack. If another telephone
has the same problem, the problem is in the telephone jack. Contact your
telephone service provider (charges may apply).
The telephone line cord may be defective. Try installing a new telephone
line cord.
My calls fade out or cut in and out when I am using the telephone.
If you are using the handset when this problem occurs, try unplugging the
coiled handset cord and firmly plugging it in the handset and telephone
base again.
If you are using the speakerphone when this problem occurs, eliminate any
background noise. Noise from the television, radio, or other appliances may
cause the speakerphone to cut in and out. Try pressing MUTE when you are
not speaking to eliminate the background noise.
Disconnect the telephone base from the telephone wall jack and plug
in another 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 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 (see Telephone
installation on page 6). The filter prevents noise and caller ID problems
caused by DSL interference. Please contact your DSL service provider for
more information about DSL filters.
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
(charges may apply).
