Troubleshooting
I cannot dial out. First, try all suggestions in There is no dial tone on
page 53.
Make sure there is a dial tone before dialing. It
is normal if the telephone takes a second or two
before producing a dial tone. Wait an extra second
before dialing.
Check that all the telephones connected to the same
telephone line are hung up.
Make sure to set the
DIAL TYPE to the correct
setting (pulse dialing or tone dialing) for the service
in your area (see
Feature summary on page 16).
If any of your other telephones are having the same
problem, the problem is in the wiring or local 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 14).
Make sure the telephone line cord and power adapter
are plugged in properly (see
Telephone installation
on page 7).
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 malfunctioning. Try
installing a new telephone line cord.
