Troubleshooting
Make sure the telephone line cord connected
to line jack L1/L2 was the one provided with
the telephone.
Make sure that the LINE GROUP assignment is
correct. See page 43 of the installation guide.
Check to make sure that each telephone set
has a unique extension number. If the sets
receive AC power at the same time, either at
initial installation or after a power failure, the
extension numbers might be the same. Refer
to the EXTENSION NUMBER section on page
32 of the installation guide.

The telephone does not
ring when there is an
incoming call.
Make sure the ringer is on (page 14).
Make sure the telephone line cord(s) and the
power adapter are plugged in properly (See
the installation guide).
There might be too many extension telephones
on the telephone line to allow all of them to
ring simultaneously. Try unplugging one phone
at a time until the phones start ringing.
Test a working telephone at the same
telephone jack. If the other telephone has the
same problem, the problem is in the telephone
jack. Contact your local telephone company
(charges may apply).
The telephone line cord might be
malfunctioning. Try installing a new telephone
line cord.
Make sure the Do Not Disturb feature is not
activated (page 15).
If you are on a call, a beep alerts you of
incoming calls on the other lines.
