FEATURES  
Your RadioShack TAD-797 Digital An-  
swering System 900MHz Cordless  
Speakerphone combines a 900MHz  
cordless telephone with a 50-memory  
Caller ID unit and a digital TAD (Tele-  
phone Answering Device).  
Telephone Features  
900 MHz Operation — provides longer  
range and less interference than many  
other cordless phones.  
Spread Spectrum Technology  
The TAD-797’s telephone uses ad-  
vanced digital spread spectrum technol-  
ogy to give you superior audio quality  
and the utmost security. Its cordless op-  
eration lets you move freely around your  
home or office.  
spreads the signal across several fre-  
quencies, providing additional security  
for your phone conversations.  
Caller ID Memory — stores up to 50  
Caller ID records.  
The TAD-797’s Caller ID unit records  
each caller’s telephone number (and  
name, if available in your area) and the  
day and time of the call, as provided by  
your local phone company to Caller ID  
service subscribers. If you have Call  
Waiting with Caller ID, the TAD-797  
shows you the incoming caller informa-  
tion, even when you are already on the  
phone.  
Call Waiting ID — you can set the TAD-  
797 to display Caller ID information  
about an incoming call when you are on  
the phone (if you subscribe to this ser-  
vice from your local phone company).  
Easy-to-Read Liquid Crystal Display  
— lets you see who is trying to reach  
you before you answer the phone.  
Speakerphone — lets you talk without  
The TAD stores up to 15 minutes of  
messages on a computer chip and  
records each message’s day and time.  
This gives you advanced capabilities  
over tape-based answering machines:  
using the handset.  
Two-Way Intercom/Paging System —  
lets you send a signal from the base to  
the handset, or from the handset to the  
base, to page someone or locate the  
handset when it is away from the base. If  
someone answers, you can use the  
TAD-797 as an intercom.  
• You can delete individual messages  
and save the rest.  
• There are no tapes to bother with  
and no tape mechanisms to wear  
out.  
Volume Controls — let you adjust the  
volume you hear through the handset  
and speakerphone.  
The remote operation feature lets you  
operate your TAD from a touch-tone  
phone (or from a rotary phone with a  
pocket tone dialer).

Security Access-Protection Code —  
helps prevent other cordless phone us-  
ers from using your phone line while the  
handset is off the base.  
COM-LOK® — ensures that other cord-  
less phone users cannot use your phone  
line when the handset is on the base.  
Remote Answer-ON— lets you call the  
TAD from a remote location even when  
it is not set to answer calls.  
Auto Talk — lets you set the handset so  
you can answer a call by simply lifting  
the handset from the base or by press-  
ing any key when the handset is away  
from the base.  
Digital Volume Control — lets you pre-  
cisely adjust the speakerphone and  
message playback.  
Prerecorded Messages — give you the  
option one of using one of two prere-  
corded outgoing messages or recording  
your own.  
Redial — lets you quickly redial the last  
number dialed.  
Flash — sends an electronic switch-  
hook signal for use with special phone  
services, such as Call Waiting.  
Announcement Only — lets you play  
an announcement for callers to hear,  
without recording their messages.  
Tone/Pulse Dialing — lets you use ei-  
ther type of service, and you can easily  
switch from pulse to tone dialing for  
long-distance, bank-by-phone, or other  
special services.

43-797.fm Page 5 Monday, August 16, 1999 9:20 AM  
Call Screening — lets you listen as a  
caller leaves a message so you can de-  
cide whether or not to answer the call.  
If you are using more than one phone or  
other device on the line, add up all the  
RENs. If the total is more than five, your  
phones 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.  
Memo Recording — lets you leave  
messages for yourself or others in your  
home or office. You can also record your  
phone conversation.  
Adjustable Ring Number — lets you  
set the TAD to answer after three or five  
rings.  
FCC STATEMENT  
Your TAD-797 complies with Part 68 of  
FCC Rules. You must, upon request,  
provide the FCC registration number  
and the REN to your phone company.  
These numbers are on the bottom of the  
base.  
Toll-Saver — lets you avoid unneces-  
sary charges when you call by long  
distance to check your messages.  
Phone Pick-Up Detection — stops re-  
cording when you pick up any phone on  
the same line as the TAD, and resets to  
answer the next call.  
You must not connect your phone to any  
of the following:  
• coin-operated systems  
• party-line systems  
READ THIS BEFORE  
INSTALLATION  
• most electronic key phone systems  
Note: Your telephone operates on stan-  
dard radio frequencies, as allocated by  
the FCC. Even though the security  
access-protection code prevents unau-  
thorized use of your phone line, it is pos-  
sible for other radio units operating on  
similar frequencies within a certain area  
to unintentionally intercept your conver-  
sations and/or cause interference. This  
lack of privacy can occur with any cord-  
less phone.  
We have designed your phone to con-  
form to federal regulations, and you can  
connect it to most telephone lines. How-  
ever, each device that you connect to  
the phone line draws power from the  
phone line. We refer to this power draw  
as the device’s ringer equivalence num-  
ber, or REN. The REN is on the bottom  
of the base.

TAD OPERATION  
SELECTING THE  
OUTGOING MESSAGE  
RECORDING/DELETING  
AN OUTGOING MESSAGE  
The TAD has two prerecorded outgoing  
messages. One asks the caller to leave  
a message: “Hello, no one is available to  
take your call. Please leave a message  
after the tone.” The TAD uses this mes-  
sage when REC TIME is set to 1 or 4 (see  
“Setting the Record Time” on Page 29).  
To record your outgoing message (up to  
30 seconds long), hold down OGM until  
the TAD beeps and --appears. When  
you finish your message, press STOP.  
The TAD plays back your message.  
The other is simply an announcement  
and does not let the caller leave a mes-  
sage: “Hello, no one is available to take  
your call.” The TAD uses this message  
when REC TIME is set to ANN (an-  
nouncement only)  
Hint: Do not tell callers that you are not  
home. Instead, say that you cannot  
come to the phone right now.  
You can also record your own message  
(see “Recording/Deleting an Outgoing  
Message”). When you record your own  
outgoing message, the TAD uses it for  
all REC TIME settings.  
Note:  
The TAD-797 cannot record an  
outgoing message less than two sec-  
onds long.  
To switch between your outgoing mes-  
sage and the TAD’s prerecorded mes-  
sage, press OGM. When the current  
message begins to play, press OGM  
again. The TAD switches to the other  
message and plays it.  
To delete your outgoing message and  
use the TAD’s prerecorded messages,  
hold down OGM until the TAD beeps.  
Then press OGM again within two sec-  
onds.

CARE AND MAINTENANCE  
Your TAD-797 Digital Answering System 900MHz Cordless Speakerphone is an ex-  
ample of superior design and craftsmanship. The following suggestions will help you  
care for your TAD-797 so you can enjoy it for years.  
Keep the TAD-797 dry. If it gets wet, wipe it dry immediately. Liquids  
might contain minerals that can corrode the electronic circuits.  
Use and store the TAD-797 only in normal temperature environments.  
Temperature extremes can shorten the life of electronic devices, dam-  
age battery packs, and distort or melt plastic parts.  
Keep the TAD-797 away from dust and dirt, which can cause premature  
wear of parts.  
Handle the TAD-797 gently and carefully. Dropping it can damage cir-  
cuit boards and cases and can cause the TAD-797 to work improperly.  
Use only a fresh battery pack of the required size and recommended  
type. Battery packs can leak chemicals that damage your TAD-797’s  
electronic parts.  
Wipe the TAD-797 with a damp cloth occasionally to keep it looking  
new. Do not use harsh chemicals, cleaning solvents, or strong deter-  
gents to clean the TAD-797.  
Modifying or tampering with the TAD-797’s internal components can cause a mal-  
function and might invalidate its warranty and void your FCC authorization to operate  
it. If your TAD-797 is not performing as it should, take it to your local RadioShack  
store for assistance. If the trouble is affecting the telephone lines, the phone company  
can ask you to disconnect your TAD-797 until you have resolved the problem.

REPLACING THE  
BATTERY PACK  
If you follow the instructions in “Connect-  
ing and Charging the Battery Pack” on  
Page 12, the battery pack should last  
about one year. If the battery pack does  
not hold a charge for more than 2 hours  
after an overnight charge, replace it with  
a new 3.6-volt, 600 mAh battery pack  
with a connector that fits the socket in  
the battery compartment. You can order  
a replacement battery pack through your  
local RadioShack store.  
4. Replace the cover.  
If you have trouble replacing the battery  
pack, take the phone to your local Ra-  
dioShack store for assistance.  
Cautions:  
Install the new battery pack as de-  
scribed below, then charge it for about  
24 hours.  
You must use a replacement battery  
pack of the same size and type.  
• Do not dispose of the battery pack in  
a fire because it might explode.  
Note: To avoid losing memory numbers,  
install and begin charging the new bat-  
tery pack within 1 minute.  
• Do not open or mutilate the battery  
pack.  
1. Press down and slide off the battery  
pack compartment cover as shown.  
• Be careful not to short the battery  
pack by touching the connector’s  
pins with conducting materials, such  
as rings, bracelets, and keys. The  
battery pack or conductor might  
overheat and burn.  
Important: This product contains a re-

chargeable nickel-cadmium  
battery  
pack. At the end of the battery pack’s  
useful life, it must be recycled or dis-  
posed of properly. Contact your local,  
county, or state hazardous waste man-  
agement authorities for information on  
recycling or disposal programs in your  
area. Some options that might be avail-  
able are: municipal curb-side collection,  
drop-off boxes at retailers such as your  
local RadioShack store, recycling collec-  
tion centers, and mail-back programs.  
3. Insert the new battery pack’s con-  
nector into the socket in the com-  
partment, place the battery pack into  
the compartment, and refasten the  
retainer strap.

If you cannot eliminate the interference,  
the FCC requires that you stop using  
your phone.  
THE FCC WANTS YOU TO  
KNOW  
In the unlikely event that your phone  
causes problems on the phone line, the  
phone company can temporarily discon-  
tinue your service. If this happens, the  
phone company attempts to notify you in  
advance. If advance notice is not practi-  
cal, the phone company notifies you as  
soon as possible and advises you of  
your right to file a complaint with the  
FCC.  
Some cordless telephones operate on  
frequencies that might cause interfer-  
ence to nearby TVs and VCRs. To mini-  
mize or prevent such interference, the  
base of the cordless telephone should  
not be placed near or on top of a TV or  
VCR.  
LIGHTNING  
Also, the phone company can make  
changes to its lines, equipment, opera-  
tions, or procedures that could affect the  
operation of this telephone. The tele-  
phone company notifies you of these  
changes in advance, so you can take  
the necessary steps to prevent interrup-  
tion of your telephone service.  
Your telephone has built-in lightning pro-  
tection to reduce the risk of damage  
from surges in telephone line and power  
line current. This lightning protection  
meets or exceeds FCC requirements.  
However, lightning striking the tele-  
phone or power lines can damage your  
telephone.  
Your phone might cause TV or radio in-  
terference even when it is operating  
properly. To determine whether your  
phone is causing the interference, turn  
off your phone. If the interference goes  
away, your phone is causing it. Try to  
eliminate the interference by:  
Lightning damage is not common. Nev-  
ertheless, if you live in an area that has  
severe electrical storms, we suggest  
that you unplug your phone during  
storms to reduce the possibility of dam-  
age.  
• moving your phone away from the  
receiver  
• connecting your phone to an AC  
outlet that is on a different electrical  
circuit from the receiver  
• contacting your local RadioShack  
store for help
