Troubleshooting
If your CID stops operating properly, these
suggestions might help.
Problem Suggestion
Display is blank. Make sure the batteries
are correctly installed and
the AC adapter is plugged
in.
Adjust the contrast (see
“Adjusting the Display
Contrast” on Page 17).
You have an
incoming call,
but do not
receive any
Caller ID infor-
mation. You answered the call
before the CID received
the call information. Wait
until your phone rings at
least once before answer-
ing a call.
Be sure that the CID is cor-
rectly and securely con-
nected.
Call your phone company
to verify that your Caller ID
service is active.
