FEATURES
Your RadioShack System 440 99-Number Memory Call Waiting Caller ID
module lets you decide whether or not to interrupt your current call when a
new call comes in. If Call Waiting/Caller ID service is available in your area
and you subscribe to it, you can see information about your incoming call
and choose whether or not you want to answer it.
The telephone company sends the caller’s telephone number (and name, if
available in your area) and the date and time of the call between the first
and second rings. During an incoming call, a Call Waiting signal sounds if
you are already on another call and the module displays the Caller ID infor-
mation to help you identify the caller and avoid unwanted calls.
The module stores and displays up to 99 single (number only) or multi-
ple (name and number) Caller ID records.
Your module includes these features:
Easy Installation
— the module easily connects to your telephone line
so you can quickly begin using it.
Call Summary
— displays the number of new calls you received.
Large Display
— makes it easy to see caller information and the current
time and date.
3
43-974.fm Page 4 Monday, August 16, 1999 4:27 PM
Clock and Date Display — displays the current time and date as provid-
ed to Caller ID service subscribers by your local telephone company.
Message Received Indicator — flashes when you get an anonymous
call, when you have at least one new call you have not reviewed, or when
you have received a voice mail message (if you have message waiting
service).
Bilingual Operation — lets you set the module to display messages in
English or Spanish.
Contrast Control — lets you adjust the display contrast for the best read-
ability.
Two Mounting Options — you can place the module on a desk, shelf,
or table, or mount it on a wall.
You need one 9-volt battery (not supplied) to protect the module’s mem-
ory if power fails.
We recommend you record the module’s serial number here. The number
is on the module’s bottom panel.
Serial Number: _________________________

This module has been tested and found to comply with all applicable UL
and FCC standards.
Important Information:
• To use this module, you must be in an area where Caller ID service
is available, and you must subscribe to the service.
• Your module displays the caller’s name only if this feature is avail-
able in your area and you subscribe to it.
• You must connect the supplied AC adapter to the module to receive
Caller ID/Call Waiting information.

43-974.fm Page 6 Monday, August 16, 1999 4:27 PM
FCC INFORMATION
We have designed your module to conform to federal regulations, and
you can connect it to most telephone lines. However, each module (and
each device, such as a telephone or answering machine) that you con-
nect to the telephone line draws power from the line. We refer to this
power draw as the module’s ringer equivalence number or REN. The
REN is shown on the bottom of the module.
If you use more than one telephone or other device on the line, add up
all of the RENs. If the total is more than five, your telephone might not
ring. In rural areas, a total REN of three might impair ringer operation. If
ringer operation is impaired, remove a device from the line.
Your module complies with Part 68 of FCC Rules. You must, upon re-
quest, provide the Federal Communications Commission (FCC) regis-
tration number and the REN to your telephone company. Both numbers
are shown on the bottom of the module.
Note:
You must not connect your module to:
• Coin-operated systems
• Party-line systems
• Most electronic key telephone systems
6
43-974.fm Page 7 Monday, August 16, 1999 4:27 PM
In the unlikely event that your module causes problems on the phone line,
the phone company can temporarily disconnect your service. If this hap-
pens, the phone company attempts to notify you in advance. If advance no-
tice is not practical, the phone company notifies you as soon as possible
and advises you of your right to file a complaint 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 module. The
phone company notifies you of these changes in advance, so you can take
the necessary steps to prevent interruption of your telephone service.
This module complies with the limits for a Class B device as specified in
Part 15 of FCC Rules. These limits provide reasonable protection against
radio and TV interference in a residential area. However, your module
might cause TV or radio interference even when it is operating properly.
To eliminate interference, you can try one or more of the following:
• Reorient or relocate the radio or TV receiving antenna
• Increase the distance between the module and the radio or TV
• Use outlets on different electrical circuits for the module and the
radio or TV
Consult your local RadioShack store if the problem continues.

OPERATION
RECEIVING AND STORING CALLS
Your System 440 allows you to see information about an incoming call
whether or not you are on the phone.
As you receive each call, your module saves a call record so you can re-
view it later. Your module saves up to 99 call records before it begins to
replace the oldest call record with a new one.
Each call record includes:
• Date and time of the call
• Call number (order the call
is received)
• Telephone number
• Caller’s name (if avail-
able)
Note:
If you have a telephone that has a HOLD feature, we do not rec-
ommend using HOLD for very long. A caller on hold might be discon-
nected if a new call comes in.

CARE AND MAINTENANCE
Your RadioShack System 440 99-Number Memory Call Waiting Caller ID
module is an example of superior design and craftsmanship. The follow-
ing suggestions will help you care for the module so you can enjoy it for
years.
• Keep the module dry. If it gets wet, wipe it dry immediately. Liquids
can contain minerals that can corrode the electronic circuits.
• Handle the module gently and carefully. Dropping it can damage
circuit boards and cases and can cause the module to work improp-
erly.
• Use and store the module only in normal temperature environ-
ments. Temperature extremes can shorten the life of electronic
devices, damage batteries, and distort or melt plastic parts.
• Keep the module away from dust and dirt, which can cause prema-
ture wear of parts.
• Wipe the module with a damp cloth occasionally to keep it looking
new. Do not use harsh chemicals, cleaning solvents, or strong
detergents to clean it.
30
43-974.fm Page 31 Monday, August 16, 1999 4:27 PM
Modifying or tampering with your module’s internal components can
cause a malfunction and might invalidate the module’s warranty and
void your FCC authorization to operate it. If your module is not operating
as it should, take it to your local RadioShack store for assistance. If the
trouble is harming the telephone lines, the telephone company might
ask you to disconnect your module until you have resolved the problem.
LIGHTNING
Your module has built-in protection circuits to reduce the risk of damage
from surges in telephone line current. These protection circuits meet or
exceed the FCC requirements. However, lightning striking the telephone
lines can damage your module.
Lightning damage is not common. However, if you live in an area that
has severe electrical storms, we suggest you unplug your module dur-
ing storms to reduce the possibility of damage.
