4Important Information
ˆImportant
Information
• To use this Caller ID (CID), you must
be in an area where Caller ID service
is available, and you must subscribe
to the service.
• Where Caller ID is offered, one or
more of the following options are gen-
erally available:
– caller’s number only
– caller’s name only
– caller’s name and number
Your CID displays the caller’s name
only if that option is available in your
area.
• The actual number of Caller ID
records your CID will store depends
on the amount of Caller ID informa-
tion sent by the phone company.
Your 2-Line CID is ETL listed to UL stan-
dards and meets all applicable FCC re-
quirements.

Important Information
FCC INFORMATION
We have designed your Caller ID (CID) to
conform to federal regulations, and you
can connect it to most telephone lines.
However, each CID (and each device,
such as a telephone or answering ma-
chine) that you connect to the telephone
line draws power from the line. We refer to
this power draw as the device’s
ringer
equivalence number,
or REN. The REN is
on the bottom of your CID.
If you use more than one phone or other
device on the line, add up all the RENs. If
the total is more than five (three in
rural areas), your phones might not ring. If
ringer operation is impaired, remove a de-
vice from the line.
Your CID complies with Part 68 of the
FCC Rules
. You must, upon request, pro-
vide the FCC registration number and the
REN to your phone company. Both num-
bers are on the bottom of the CID.
You must not connect your CID to:
• coin-operated systems
• party-line systems

6Important Information
• most electronic key telephone sys-
tems
In the unlikely event that your CID causes
problems on the phone line, the phone
company can temporarily disconnect your
service. If this happens, the phone com-
pany attempts to notify you in advance. If
advance notice is not practical, the phone
company notifies you as soon as possible
and advises you of your right to file a com-
plaint with the FCC.
Also, the phone company can make
changes to its lines, equipment, opera-
tions, or procedures that could affect the
operation of this CID. The phone company
notifies you of these changes in advance,
so you can take the necessary steps to
prevent interruption of your phone service.
This CID complies with the limits for a
Class B digital device as specified in Part
15 of the
FCC Rules
. These limits provide
reasonable protection against radio and
TV interference in a residential area. How-
ever, your equipment might cause TV or
radio interference even when it is operat-
ing properly.

7
Important Information
To eliminate interference, you can try one
or more of the following corrective mea-
sures:
• Reorient or relocate the TV or radio’s
receiving antenna.
• Increase the distance between the
CID and the radio or TV.
• Use outlets on different electrical cir-
cuits for the equipment and the radio
or TV.
Consult your local RadioShack store if the
problem continues.
LIGHTNING
Your CID has built-in protection circuits to
reduce the risk of damage from surges in
telephone and power line current. These
protection circuits meet or exceed the
FCC requirements. However, lightning
striking the telephone or power lines can
damage your CID.
Lightning damage is not common. Never-
theless, if you live in an area that has se-
vere electrical storms, we suggest that
you unplug your CID when storms
approach to reduce the possibility of dam-
age.

8Features
ˆ Features
Your RadioShack 2-Line Caller ID (CID) is
a combination of two Caller IDs. Its two
separate displays and function keys for
each line let you view call records easily. It
stores and displays up to 100 multiple
(name and number) or number-only Caller
ID records for two telephone lines (50 for
each line). The CID displays the caller’s
telephone number (and name, if available
in your area) and the date and time the
call was received, as provided by your lo-
cal phone company to Caller ID service
subscribers.
Note: Check with your local phone com-
pany regarding name service availability.
Your CID includes these features:
Three-Line Liquid Crystal Display —
makes it easy to see the caller information
and the current time and date simulta-
neously.
Trilingual Operation — lets you select
English, French, or Spanish as the mes-
sage display.

9
Features
Call Counter — shows the number of
calls you have received.
New Call Indicator — lets you see at a
glance that you have new calls.
Clock — displays the current time and
date as provided to Caller ID service sub-
scribers by your local telephone company.
Reviewing Scrolling — lets you easily
scroll through all records in Caller ID
memory.
Contrast Control — lets you adjust the
display contrast to match your preference.
Message Waiting — tells you when you
have received a voice mail message (if
you subscribe to the message waiting ser-
vice from your local phone company).
Note: The Message Waiting feature does
not work with stutter dial tone service.
Check with your telephone company for
the type of service you have.

INSTALLING BATTERIES/
SETUP
You need six AAA batteries (not supplied)
to power the CID. For the longest opera-
tion and best performance, we recom-
mend alkaline batteries, available at your
local RadioShack store.
Cautions:
• Always use fresh batteries of the
required size and recommended
type.
• Do not mix old and new batteries, dif-
ferent types of batteries (alkaline,
standard, or rechargeable), or
rechargeable batteries of different
capacities.
Follow these steps to install batteries.
1. Use a Phillips screwdriver to remove
the battery compartment screw on
the bottom of the CID and slide off the
cover.
