needs to be replaced.
• Remove and re-install the battery.
The telephone does not
ring when there is an
incoming call.
Troubleshooting
• Make sure the ringer is on (page 33).
• Make sure the telephone line cord(s) and the
power adapter are plugged in properly (See
pages 11-15).
• There may 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 another 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 (see the DO NOT DISTURB section on
the user’s manual).
• Make sure the ringer delay time (page 34) is not
longer than the answer delay time of the answer-
ing system (see the ANSWER DELAY section on
page 58). This would cause the answering system
to answer the call before the phone rings.
• If you are on a call, a beep alerts you of
incoming calls on the other lines.
• Make sure that the
LINE GROUP assignment is
correct. See page 43.
• All extensions must have the same outside telephone
line connected to Line 1.
• Make sure the telephone line cord connected to
line jack
L1/L2 was provided with the telephone.
• 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 may be the same. Refer
to the EXTENSION NUMBER section on page 32.
• Make sure that the LINE GROUP assignment is
correct. See page 43.
