Possible Solution / Cause
•
Check the power connection.
•
Check the telephone line cord connections.
•
Check the batteries for proper installation.
•
The Caller ID unit will not function until you have Caller ID
service provided by your local phone company. Call your
local phone company to have Caller ID installed on your
telephone line.
•
Check your telephone line connections. Make sure all
connections are secure and connected.
•
If you pick up the phone before the second ring, the caller
information will not be correctly received. If you have
telephone answering device (TAD) connected with the unit,
set the TAD to answer after two rings or more.
•
If it is a blocked call or an out-of-area call, the caller's name
and / or phone number will not appear on the display.
•
If only the caller's phone number appears on the display, it
may be a Single Data Message Format (SDMF) call, as
opposed to a Multiple Data Message Format (MDMF) call.
Please call your local phone company to see which service
you have.
•
On rare occasions, the Caller ID information sent by the
telephone company may have an error in the transmission.
This is not the fault of your Caller ID unit. It can only capture
and store the data that was received.
•
Subscription to Caller ID Call Waiting (CIDCW) is required
from your local phone company for the CIDCW function to
operate properly. Call you local phone company for details.
