Trouble Hearing Called Party
Possible Cause 1: If a speakerphone is being used, there may be
environmental factors that affect the performance of the speaker or microphone
(for example, too much background noise).
What to do: Eliminate the background noise or other interference. If the problem
persists or if a speakerphone is not being used, go to Possible Cause 2.
Possible Cause 2: The telephone handset may be defective.
What to do: Replace the handset with a handset from the same type of
telephone. If you can now hear the called party, contact your AT&T
representative to order a new handset. If you still have trouble hearing, go to
Possible Cause 3.
Possible Cause 3: The telephone may be defective.
What to do: Test the telephone by replacing it with a similar telephone that you
know is working properly.
■
If you can hear the called party on the replacement telephone, then
replace it with the original telephone and check again. If you still have
trouble hearing the called party on the original telephone, then the
original telephone may be defective. Call the AT&T Helpline at
1 800 628-2888.
■
If you cannot hear the called party on the replacement telephone, there
may be a problem with the system wiring or the control unit. Call the
AT&T Helpline at 1 800 628-2888.
Programmed Button Fails
NOTE:
Extension programming is
not stored in the telephone itself. Therefore, if you
move a telephone to a different extension, the programming for the previous
telephone at that extension remains in effect. The extension must be
reprogrammed as appropriate.
Possible Cause 1: The programmed button may be incorrectly programmed or
may not be programmed at all.
