INSTRUCTIONS IN THE OWNER'S MANUAL.
• 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.
• 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
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.
