Troubleshooting
If any of your other telephones are having the
same problem, the problem is in the wiring
or telephone service. Contact your telephone
service provider (charges may apply).
If you are using the speakerphone, eliminate
any background noise. Noise from a television,
radio, or other appliances might cause the
telephone to not dial out properly. If you
cannot eliminate the background noise, first try
muting the telephone before dialing, or dialing
from another room in your home with less
background noise.
The telephone does not
ring when there is an
incoming call.
Make sure the ringer is on (see Ringer volume
on page 13).
Make sure the telephone line cord is plugged in
properly (see Telephone installation on page 8).
There might 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 might 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 might cause the speakerphone to
cut in and out. Try pressing MUTE when you are
not speaking to eliminate the background noise.
