Phone Does Not Ring
Possible Cause 1: Volume set too low (system phone) or turned off (standard phone).
What to do: Press the volume control button to increase ringer volume, or turn ringer on.
■
If the phone rings increasingly louder, the problem is solved.
■
If the phone still does not ring, go to Possible Cause 2.
Possible Cause 2: Phone’s Line Ringing may be set to No Ring.
What to do: Check to see if the phone’s Line Ringing is set to No Ring.
■
If Line Ringing is set for No Ring, change it if necessary.
■
If Line Ringing is set to Ring, the phone may be faulty. Follow the procedure for
“Other Problems with Phones.”
Calls Are Answered Automatically
A call rings once, then disappears as if it were answered.
Possible Cause: An auxiliary device answers when it should not (could occur with a fax
machine, answering machine, or modem).
What to do: Be sure the device is set to answer correctly. If the device answers before it
should, adjust it to answer on a later ring. If the device should not answer calls at all, turn
its auto-answer feature off. Refer to the device’s user manual.
■
If the auxiliary device no longer answers calls automatically, then the problem is
solved.
■
If the problem remains, call the hotline.*
Trouble Hearing Called Party
Possible Cause: If you are using a speakerphone, the volume may be too low or there may
be environmental factors that affect the performance of the speaker or microphone (for
example, too much background noise).
What to do: Try increasing the speakerphone volume. Also see “Speakerphone
Performance Tips” in Chapter 3 for suggestions on the proper use of the speakerphone.

If the problem remains, call the hotline.*
