Single-Line Telephone Problems
11-10
Possible Cause 3: Line Ringing is programmed for No Ring or Delayed Ring.
What to do: Check the Line Ringing setting for the extension.
■ If Line Ringing is set for No Ring or Delayed Ring, change the setting if appropriate.
■ If Line Ringing is set for Immediate Ring and this telephone is part of a combination
extension, see “Problems with Combination Extensions” on page 11-16.
■ If Line Ringing is set for Immediate Ring and the telephone is on an extension by itself, go to
Possible Cause 4.
Possible Cause 4: Telephone is faulty.
What to do: Unplug the problem telephone. Plug in a single-line telephone that you know rings
properly.
■ If the replacement telephone rings properly, the problem telephone is defective. Replace it.
■ If the replacement telephone does not ring properly, call the helpline number listed on the
front, inside cover.
Single-Line Telephone Rings Back after
Intercom Call with No One at Other End 11

back.
What to do: Replace the handset carefully. If the problem is not solved, go to Possible Cause 2.
Possible Cause 2: Automatic Line Selection is programmed incorrectly.
What to do: If one of the telephones involved is a single-line rotary or touch-tone telephone, set its
Automatic Line Selection to intercom first. If the problem is not solved, call the helpline number
listed on the front, inside cover.
Single-Line Telephone’s Message Waiting Light Does
Not Light 11
Possible Cause 1: The telephone is part of a combination extension which includes a system
telephone that has Background Music on.
What to do: Check to see if the system telephone has Background Music on. A single-line
telephone’s message waiting light will not light if Background Music is on at the system telephone.
■ If Background Music is on, turn it off. If the single-line telephone’s message waiting light
lights properly, the problem is solved.
■ If Background Music is not on, go to Possible Cause 2.
