Troubleshooting
Cannot join a conversation
in progress.
• The call privacy feature prevents another set
on the system from interrupting a conversation.
Make sure you press the LINE button to release
privacy. (See Call privacy on page 21.)
• Make sure the ringer is on (page 13).
• 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 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 (page 15).
• Make sure the ringer delay time (page 34 of the
installation guide) is not longer than the answer
delay time of the answering system (page 58 of
the installation guide). Otherwise, the answering
system answers 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 of the installation guide.
The telephone does not
ring when there is an
incoming call.
LOW BATT appears on
screen.
• No spare battery is installed or the spare
battery needs to be replaced.
• Remove and re-install the battery.
• 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 (page 32 of
the installation guide).
