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 rmly 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 lter between the
telephone line cord and the telephone wall jack (see Telephone installation
on page 6). The lter prevents noise and caller ID problems caused by DSL
interference. Please contact your DSL service provider for more information
about DSL lters.
I hear other calls when using the telephone.
Disconnect the telephone base from the telephone wall jack. Plug in a
dierent 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).
