SOLUTION
Check the power connections.
Check the telephone line cord connections.
Check the batteries for proper installation.
The handset LCD panel will only start displaying
information after the first call is received.
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 have a 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.
On rare occasions, the Caller ID information sent by the
telephone company may have an error during the
transmission. This is not the fault of your Caller ID unit.
The DEL/CHAN button must be pressed and held for at
least two seconds.
Subscription to Caller ID Call Waiting (CIDCW) is
required from your local phone company for the CIDCW
function to operate properly. Call your local phone
company for details.
